| 1 | Comparison of the effect and safety of Kuntai capsule and hormone replacement therapy in patients with perimenopausal syndrome:a systematic review and Meta-analysis显示文摘OBJECTIVE: To assess the effectiveness and safety of Kuntai capsule and hormone replacement therapy in treatment of perimenopausal syndrome.METHODS: Articles were retrieved from the databases Cochrane Database of Systematic Reviews,Pub Med, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database. Only randomized controlled trials were included; 15 trials involving1243 patients were identified from January 2005 to April 2015. A systemic review and Meta-analysis of publications was performed. The review was limit-ed to randomized controlled trials that compared Kuntai capsule and hormone replacement therapy to treat perimenopausal syndrome for at least 3months. The primary outcome assessed was the treatment efficacy at 3 months, including effective rate of Kupperman menopausal scores, Kupperman menopausal scores, and blood estradiol(E2) or blood follicle stimulating hormone(FSH) levels.Other outcomes assessed were safety or adverse events, such as gastrointestinal complaints, breast distending pain, or vaginal bleeding.RESULTS: Kupperman menopausal scores showed no significant difference in effective rate [odds ratio(OR): 1.05, 95% confidence intervals(CI): 0.71 to1.55] and changes in FSH level [mean difference(MD): 2.14, 95% CI:-2.36 to 6.65]. There was a significant statistical difference in Kupperman menopausal scores(MD:-1.14, 95% CI:-2.03 to-0.25)and changes in E2level(MD:-16.41, 95% CI:-18.83to-13.69). There were fewer adverse events in the Kuntai capsule group than in the hormone replacement therapy group(OR: = 0.35, 95% CI: 0.25 to0.48, P < 0.01).CONCLUSION: Compared with hormone replacement therapy, Kuntai capsule can improve perimenopausal symptoms and blood E2 levels, and reduce the incidence of adverse events. | Du Xiaoqin Xu Lin Wang Lijun Heng Mingli Bu Huaien Hao Yu Tian Jinhui | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 28 |
| 2 | Clinical significance of matrix metalloproteinase-9 expression in esophageal squamous cell carcinoma显示文摘AIM: To evaluate the expression of matrix metalloproteinase9 (MMP-9) and its clinical significance in esophageal squamous cell carcinoma (ESCC).METHODS: The expression of MMP-9 in 208 cases of ESCC was detected by immunohistochemistry (IHC) and its clinical significance in ESCC especially the relationship with the clinicopathological parameters was analyzed.RESULTS: The percentage of positive cases for MMP-9detected by IHC was 49.0%. MMP-9 was mainly expressed in the cytoplasm of cancer cells especially in the invasive front. Only weak expression was detected in the stromal cells and no expression in non-cancerous mucosa. The expression of MMP-9 was positively correlated with poorer differentiation (P = 0.001<0.01), existence of vessel permeation (P = 0.027<0.05) and lymph node metastasis (P = 0.027<0.05).CONCLJSION: The expression of MMP-9 correlates with the cancer cell differentiation, vessel permeation and lymph node metastasis. It may be a novel biomarker for the diagnosis and treatment of ESCC. | Zhen-DongGu Ke-NengChen MingLi JinGu Ji-YouLi | 2005 | World Journal of Gastroenterology2005，11，6： | 18 |
| 3 | Technology and Experiments of 42CrMo Bearing Ring Forming Based on Casting Ring Blank显示文摘Bearing ring is the crucial component of bearing. With regard to such problems as material waste, low efficiency and high energy consumption in current process of producing large bearing ring, a new process named 'casting-rolling compound forming technology' is researched by taking the typical 42CrMo slew bearing as object. Through theoretical analysis, the design criteria of the main casting-rolling forming parameters are put forward at first. Then the constitutive relationship model of as-cast 42CrMo steel and its mathematical model of dynamic recrystallization are obtained according to the results of the hot compression experiment. By a coupled thermal-mechanical finite element model for radial-axial rolling of bearing ring, the fraction of dynamic recrystallization is calculated and recrystallized grains size are predicated. Meanwhile, the effects of the initial rolling temperature and feed rate of idle roll on material microstructure evolution are analyzed. Finally, the industrial rolling experiment is designed and performed, based on the simulation results. In addition, mechanical and metallographic tests are conducted on rolled bearing ring to get the mechanical parameters and metallographic structure. The experimental data and results show that the mechanical properties of bearing ring produced by casting-rolling compound forming technology are up to industrial standard, and a qualified bearing ring can be successfully formed by employing this new technology. Through the study, a process of forming large bearing ring directly by using casting ring blank is obtained, which could provide an effective theoretical guidance for manufacturing large ring parts. It also has an edge in saving material, lowering energy and improving efficiency. | LI Yongtang JU Li QI Huiping ZHANG Feng CHEN Guozhen WANG Mingli | 2014 | Chinese Journal of Mechanical Engineering2014，27，2： | 16 |

| 5 | A vaccinia replication system for producing recombinant hepatitis C virus显示文摘AIM: To develop a cell culture system capable of producing high titer hepatitis C virus (HCV) stocks with recombinant vaccinia viruses as helpers.METHODS: Two plasmids were used for the generation of recombinant HCV: one containing the full-length HCV cDNA cloned between T7 promoter and T7 terminator of pOCUS-T7 vector, and the other containing the HCV polyprotein open reading frame (ORF) directly linked to a vaccinia late promoter in PSC59. These two plasmids were co-transfected into BHK21 cells, which were then infected with vTF7-3 recombinant vaccinia helper viruses.RESULTS: After 5 d of incubation, approximately 3.6×10^7 copies of HCV RNA were present per milliliter of cell culture supematant, as detected by fluorescence quantitative RT-PCR(FQ-PCR). The yield of recombinant HCV using this cell system increased 100- to 1000- fold compared to in vitrotranscribed HCV genomic RNA or selective subgenomic HCV RNA molecule method.CONCLUSION: This cell culture system is capable of producing high titer recombinant HCV. | Ying-SongWu YuFeng Wen-QiDong Yan-MingZhang MingLi | 2004 | World Journal of Gastroenterology2004，10，18： | 12 |
| 6 | Nitrogen-doped fluorescence carbon dots as multi-mechanism detection for iodide and curcumin in biological and food samples显示文摘Iodine ion is one of the most indispensable anions in living organisms,particularly being an important substance for the synthesis of thyroid hormones.Curcumin is a yellow-orange polyphenol compound derived from the rhizome of Curcuma longa L.,which has been commonly used as a spice and natural coloring agent,food additives,cosmetics as well as Chinese medicine.However,excess curcumin may cause DNA inactivation,lead to a decrease in intracellular ATP levels,and trigger the tissue necrosis.Therefore,quantitative detection of iodine and curcumin is of great significance in the fields of food and life sciences.Herein,we develop nitrogen-doped fluorescent carbon dots(NCDs)as a multi-mechanism detection for iodide and curcumin in actual complex biological and food samples,which was prepared by a one-step solid-phase synthesis using tartaric acid and urea as precursors without adding any other reagents.An assembled NCDs-Hg^(2+) fluorescence-enhanced sensor for the quantitative detection of I^(-) was established based on a fluorescence“turn-off-on”mechanism in a linear range of 0.3-15μM with a detection limit of 69.4 nM and successfully quantified trace amounts of I^(-) in water samples and urine sample.Meanwhile,the as-synthesized NCDs also can be used as a fluorescent quenched sensor for curcumin detection based on the synergistic internal filtration effect(IFE)and static quenching,achieving a good linear range of 0.1-20μM with a satisfactory detection limit of 29.8 nM.These results indicate that carbon dots are potential sensing materials for iodine and curcumin detection for the good of our health. | Xiaodan Tang Hongmei Yu Brian Bui Lingyun Wang Christina Xing Shaoyan Wang Mingli Chen Zhizhi Hu Wei Chen | 2021 | Bioactive Materials2021，6，6： | 11 |
| 7 | Adsorption of VOCs on reduced graphene oxide显示文摘A modified Hummer's method was adopted for the synthesis of graphene oxide(GO) and reduced graphene oxide(rGO). It was revealed that the modified method is effective for the production of GO and rGO from graphite. Transmission electron microscopy(TEM) images of GO and rGO showed a sheet-like morphology. Because of the presence of oxygenated functional groups on the carbon surface, the interlayer spacing of the prepared GO was higher than that of rGO. The presence of \OH and C_O groups in the Fourier transform infrared spectra(FTIR) spectrum and G-mode and 2D-mode in Raman spectra confirmed the synthesis of GO and rGO. rGO(292.6 m^2/g) showed higher surface area than that of GO(236.4 m^2/g). The prepared rGO was used as an adsorbent for benzene and toluene(model pollutants of volatile organic compounds(VOCs)) under dynamic adsorption/desorption conditions. rGO showed higher adsorption capacity and breakthrough times than GO. The adsorption capacity of rGO for benzene and toluene was 276.4 and 304.4 mg/g, respectively.Desorption experiments showed that the spent rGO can be successfully regenerated by heating at 150.0°C. Its excellent adsorption/desorption performance for benzene and toluene makes rGO a potential adsorbent for VOC adsorption. | Lian Yu Long Wang Weicheng Xu Limin Chen Mingli Fu Junliang Wu Daiqi Ye | 2018 | Journal of Environmental Sciences2018，30，5： | 10 |
| 8 | FLEXIBLE MAGNETIC WHEEL TYPE INTELLIGENT WELDING ROBOT FOR SPHERICAL TANK显示文摘An intelligent welding robot for spherical tank's all-position multi-layer welds is developed. Based on the dynamics analyzing and simulation testing, a flexible magnetic wheel mechanism is created as the robot's walking carriage. It makes the robot directly attracted to the surface of the spherical tank so as to realize the all-position walking and welding without rail. At the same time, a CCD real-time tracing system is developed for the robot to repeatedly trace the all-position and multi-layer seams. The welding tests show that the welding robot can make the all-position and multi-layer welds with high tracing accuracy, excellent quality and reliable behavior, and it can be applied for practical production. | Jiang Lipei Jiao Xiangdong Xue Long Ma Hongze Li Mingli Yang Zhaochun Department of Mechanical Engineering, Institute of Petro-chemical Technology,Beijing 102600, China | 2002 | Chinese Journal of Mechanical Engineering2002，15，2： | 9 |
| 9 | Seasonal Variations in Phytoplankton Community Structure in the Sanggou,Ailian,and Lidao Bays显示文摘The seasonal variations in phytoplankton community structure were investigated for the Sanggou Bay(SGB) and the adjacent Ailian Bay(ALB) and Lidao Bay(LDB) in Shandong Peninsula, eastern China. The species composition and cell abundance of phytoplankton in the bay waters in spring(April 2011), summer(August 2011), autumn(October 2011), and winter(January 2012) were examined using the Utermhl method. A total of 80 taxa of phytoplankton that belong to 39 genera of 3 phyla were identified. These included 64 species of 30 genera in the Phylum Bacillariophyta, 13 species of 8 genera in the Phylum Dinophyta, and 3 species of 1 genus in the Phylum Chrysophyta. During the four seasons, the number of phytoplankton species(43) was the highest in spring, followed by summer and autumn(40), and the lowest number of phytoplankton species(35) was found in winter. Diatoms, especially Paralia sulcata(Ehrenberg) Cleve and Coscinodiscus oculus-iridis Ehrenberg, were predominant in the phytoplankton community throughout the study period, whereas the dominance of dinoflagellate appeared in summer only. The maximum cell abundance of phytoplankton was detected in summer(average 8.08 × 103 cells L-1) whereas their minimum abundance was found in autumn(average 2.60 × 103 cells L-1). The phytoplankton abundance was generally higher in the outer bay than in the inner bay in spring and autumn. In summer, the phytoplankton cells were mainly concentrated in the south of inner SGB, with peak abundance observed along the western coast. In winter, the distribution of phytoplankton cells showed 3 patches, with peak abundance along the western coast as well. On seasonal average, the Shannon-Wiener diversity indices of phytoplankton community ranged from 1.17 to 1.78(autumn > summer > spring > winter), and the Pielou's evenness indices of phytoplankton ranged from 0.45 to 0.65(autumn > spring > summer > winter). According to the results of canonical correspondence analysis, phosphate level was the major factor that limited the occurrence of P. sulcata and C. oculus-iridis, whereas optimal temperature and low salinity were responsible for Prorocentrum blooms in summer. The detailed description of seasonal variations in phytoplankton community structure in the three bays provide reference data for future studies on marine ecosystems and mariculture in adjacent areas. | YUAN Mingli ZHANG Cuixia JIANG Zengjie GUO Shujin SUN Jun | 2014 | Journal of Ocean University of China2014，13，6： | 9 |
| 10 | Review of low timing jitter mode-locked fiber lasers and applications in dual-comb absolute distance measurement显示文摘Passively mode-locked fiber lasers emit femtosecond pulse trains with excellent short-term stability. The quantum-limited timing jitter of a free running femtosecond erbium-doped fiber laser working at room temperature is considerably below one femtosecond at high Fourier frequency. The ultrashort pulse train with ultralow timing jitter enables absolute time-of-flight measurements based on a dual-comb implementation, which is typically composed of a pair of optical frequency combs generated by femtosecond lasers. Dead-zone-free absolute distance measurement with sub-micrometer precision and kHz update rate has been routinely achieved with a dual-comb configuration, which is promising for a number of precision manufacturing applications, from large step-structure measurements prevalent in microelectronic profilometry to three coordinate measurements in large-scale aerospace manufacturing and shipbuilding. In this paper, we first review the sub-femtosecond precision timing jitter characterization methods and approaches for ultralow timing jitter mode-locked fiber laser design. Then, we provide an overview of the state-of-the-art dual-comb absolute ranging technology in terms of working principles, experimental implementations, and measurement precisions. Finally, we discuss the impact of quantum-limited timing jitter on the dual-comb ranging precision at a high update rate. The route to highprecision dual-comb range finder design based on ultralow jitter femtosecond fiber lasers is proposed. | Haosen Shi Youjian Song Runmin Li Yuepeng Li Hui Cao Haochen Tian Bowen Liu Lu Chai Minglie Hu | 2018 | Nanotechnology and Precision Engineering2018，1，4： | 9 |

| 12 | Toluene decomposition performance and NOx by-product formation during a DBD-catalyst process显示文摘Characteristics of toluene decomposition and formation of nitrogen oxide(NOx) by-products were investigated in a dielectric barrier discharge(DBD) reactor with/without catalyst at room temperature and atmospheric pressure. Four kinds of metal oxides, i.e., manganese oxide(Mn Ox), iron oxide(Fe Ox), cobalt oxide(Co Ox) and copper oxide(Cu O), supported on Al2O3/nickel foam, were used as catalysts. It was found that introducing catalysts could improve toluene removal efficiency, promote decomposition of by-product ozone and enhance CO2 selectivity. In addition, NOx was suppressed with the decrease of specific energy density(SED) and the increase of humidity, gas flow rate and toluene concentration, or catalyst introduction. Among the four kinds of catalysts, the Cu O catalyst showed the best performance in NOx suppression. The Mn Ox catalyst exhibited the lowest concentration of O3 and highest CO2 selectivity but the highest concentration of NOx. A possible pathway for NOx production in DBD was discussed. The contributions of oxygen active species and hydroxyl radicals are dominant in NOx suppression. | Yufang Guo Xiaobin Liao Mingli Fu Haibao Huang Daiqi Ye | 2015 | Journal of Environmental Sciences2015，27，2： | 7 |
| 13 | Highly efficient Cu/anatase TiO2 {001}-nanosheets catalysts for methanol synthesis from CO2显示文摘Anatase TiO_2 nanosheets(-ns-) with dominant exposed {001} facets were used as support to load copper,and the synthesized Cu/TiO_2-ns catalysts were evaluated for CO_2 hydrogenation to methanol. Under the reaction conditions, P = 3.0 MPa, T = 260 ℃, V(N_2):V(H_2):V(CO_2) = 8:69:23 and gas hourly space velocity(GHSV) = 3600 mL g^(-1)h^(-1), the methanol yield reached an appealing high value, 5.6%. Copper-loading amount, calcination temperature and reduction atmosphere have been investigated in this work, which significantly influence the particle sizes of copper and/or the defect concentration in TiO_2, then leading to different catalytic performance. Characterizations of XRD, EPR, CO_2-TPD and FTIR demonstrate that higher specific surface area of Cu is good for the hydrogenation of CO_2 and adequate amount of Ti^(3+) plays important roles in CO_2 activation. Both of them facilitate high turnover frequency(TOF) of methanol formation. | Yunfeng Bao Chunlei Huang Limin Chen Yu dong Zhang Long Liang Jinjun Wen Mingli Fu Junliang Wu Daiqi Ye | 2018 | Journal of Energy Chemistry2018，27，2： | 7 |
| 14 | Target delineation and dose prescription of adaptive replanning intensity-modulated radiotherapy for nasopharyngeal carcinoma显示文摘Dear Editor,Intensity-modulated radiotherapy(IMRT)has a distinct advantage of high conformity and is an appropriate tech-nique for treating nasopharyngeal carcinoma(NPC).Pre-vious studies have demonstrated that anatomical changes in the external contour,shape,and location of the target and critical structures are significant and result in dosi-metric changes[1,2].Patients’quality of life and clini-cal outcomes might be improved by IMRT replanning[3].Therefore,replanning strategies should be consid-ered instead of single-planning strategies throughout the entire course of radiotherapy.However,there are sub-stantial controversies on(1)the appropriate time for tar-get redelineation,(2)how to modify the target volumes,and(3)how to evaluate the modified plans.The present study provides a new perspective in replanning with regard to these three aspects. | Dehuan Xie Wanqin Cheng Shaowen Lv Rui Zhong Lei Wang Jiang Hu Mingli Wang Shaomin Huang Yong Su Yunfei Xia | 2019 | Cancer Communications2019，39，1： | 7 |

| 16 | Neurocognitive Graphs of First-Episode Schizophrenia and Major Depression Based on Cognitive Features显示文摘Neurocognitive deficits are frequently observed in patients with schizophrenia and major depressive disorder(MDD). The relations between cognitive features may be represented by neurocognitive graphs based on cognitive features, modeled as Gaussian Markov random fields. However, it is unclear whether it is possible to differentiate between phenotypic patterns associated with the differential diagnosis of schizophrenia and depression using this neurocognitive graph approach. In this study, we enrolled 215 first-episode patients with schizophrenia(FES), 125 with MDD, and 237 demographically-matched healthy controls(HCs). The cognitive performance of all participants was evaluated using a battery of neurocognitive tests. The graphical LASSO model was trained with aone-vs-one scenario to learn the conditional independent structure of neurocognitive features of each group. Participants in the holdout dataset were classified into different groups with the highest likelihood. A partial correlation matrix was transformed from the graphical model to further explore the neurocognitive graph for each group. The classification approach identified the diagnostic class for individuals with an average accuracy of 73.41% for FES vs HC, 67.07% for MDD vs HC, and 59.48% for FES vs MDD. Both of the neurocognitive graphs for FES and MDD had more connections and higher node centrality than those for HC. The neurocognitive graph for FES was less sparse and had more connections than that for MDD.Thus, neurocognitive graphs based on cognitive features are promising for describing endophenotypes that may discriminate schizophrenia from depression. | Sugai Liang Roberto Vega Xiangzhen Kong Wei Deng Qiang Wang Xiaohong Ma Mingli Li Xun Hu Andrew J.Greenshaw Russell Greiner Tao Li | 2018 | Neuroscience Bulletin2018，34，2： | 6 |
| 17 | Doping bioactive elements into a collagen scaffold based on synchronous self-assembly/mineralization for bone tissue engineering显示文摘Pure collagen is biocompatible but lacks inherent osteoinductive,osteoimmunomodulatory and antibacterial activities.To obtain collagen with these characteristics,we developed a novel methodology of doping bioactive elements into collagen through the synchronous self-assembly/mineralization(SSM)of collagen.In the SSM model,amorphous mineral nanoparticles(AMN)(amorphous SrCO3,amorphous Ag3PO4,etc.)stabilized by the polyampholyte,carboxymethyl chitosan(CMC),and collagen molecules were the primary components under acidic conditions.As the pH gradually increased,intrafibrillar mineralization occurred via the self-adaptive interaction between the AMNs and the collagen microfibrils,which were self-assembling;the AMNs wrapped around the microfibrils became situated in the gap zones of collagen and finally transformed into crystals.Srdoped collagen scaffolds(Sr-CS)promoted in vitro cell proliferation and osteogenic differentiation of rat bone marrow mesenchymal stromal cells(rBMSCs)and synergistically improved osteogenesis of rBMSCs by altering the macrophage response.Ag-doped collagen scaffolds(Ag-CS)exhibited in vitro antibacterial effects on S.aureus,as well as cell/tissue compatibility.Moreover,Sr-CS implanted into the calvarial defect of a rat resulted in improved bone regeneration.Therefore,the SSM model is a de novo synthetic strategy for doping bioactive elements into collagen,and can be used to fabricate multifunctional collagen scaffolds to meet the clinical challenges of encouraging osteogenesis,boosting the immune response and fighting severe infection in bone defects. | Huanhuan Liu Mingli Lin Xue Liu Ye Zhang Yuyu Luo Yanyun Pang Haitao Chen Dongwang Zhu Xue Zhong Shiqing Ma Yanhong Zhao Qiang Yang Xu Zhang | 2020 | Bioactive Materials2020，5，4： | 6 |
| 18 | Angiography for diagnosis and treatment of colorectal cancer显示文摘AIM: To evaluate the role of preoperative angiography inthe diagnosis and treatment of colorectal cancer.METHODS: The authors performed selective arterialcannulation by Seldinger's method in 47 patients to locatethe primary cancer and to diagnose metastasis to the liver.Each patient was then given intra-arterial regionalchemotherapy, and received 5-fluorouracil (5-Fu, 1 000 mg),mitomycin C (MMC, 20 mg), and cisplatinum (CDDP, 80 mg).RESULTS: The location and shape of each tumor wereobserved, including metastatic tumors in the liver, in 42 ofthe 47 (89.4 %) patients. The site of the primary tumor wasdifficult to identify in 5 cases because the patients had arecurrence of cancer. Arterial chemotherapy was performedsuccessfully in all patients. The authors recorded no partialor significant morbidity resulted from angiography. The onlyincident was bleeding from the artery puncture site in onepatient, which was successfully stopped by generalmedication.CONCLUSION: Preoperative selective arterial angiographycan help the diagnosis and locate primary tumors and todetect liver metastasis. At the same time, regional arterialchemotherapy can be an important form of preoperativetherapy. | JinGu Zhao-LaiMa YingLi MingLi Guang-WeiXu | 2003 | World Journal of Gastroenterology2003，9，2： | 6 |
| 19 | Effects of redox potential on soil cadmium solubility:Insight into microbial community显示文摘Understanding the role of microbes in the solubility of cadmium(Cd) is of fundamental importance for remediation of Cd toxicity. The present study aimed to identify the microbes that involved in regulating Cd solubility and to reveal possible mechanisms. Therefore,microbial communities were investigated through high-throughput sequencing approach, the molecular ecological network was constructed and metagenomes were predicted. Our results indicated that redox conditions affected both the solubility of soil Cd and the microbial communities. Anaerobic microbes, such as Anaerolineaceae, did not only play important roles in shaping the microbial community in soils, but might also be involved in regulating the Cd solubility. Two possible mechanisms that how Anaerolineaceae involved in Cd solubility are(1) Anaerolineaceae are important organic matter degraders under anoxic conditions and(2) Anaerolineaceae can co-exist with methane metabolism microbes, while methane metabolism promotes the precipitation of soluble Cd. Thus, application of Anaerolineaceae in bioremediation of soil Cadmium contamination is a potential approach. The study provided a novel insight into the role of microbial community in the regulation of Cd solubility under different redox conditions, and suggested a potential approach for the remediation of soil Cd contamination. | Delong Meng Juan Li Tianbo Liu Yongjun Liu Mingli Yan Jin Hu Xiaoqi Li Xueduan Liu Yili Liang Hongwei Liu Huaqun Yin | 2019 | Journal of Environmental Sciences2019，31，1： | 6 |
| 20 | Markov repairable systems with stochastic regimes switching显示文摘Compared with the classical Markov repairable system,the Markov repairable system with stochastic regimes switching introduced in the paper provides a more realistic description of the practical system.The system can be used to model the dynamics of a repairable system whose performance regimes switch according to the external conditions.For example,to satisfy the demand variation that is typical for the power and communication systems and reduce the cost,these systems usually adjust their operating regimes.The transition rate matrices under distinct operating regimes are assumed to be different and the sojourn times in distinct regimes are governed by a finite state Markov chain.By using the theory of Markov process,Ion channel theory,and Laplace transforms,the up time of the system are studied.A numerical example is given to illustrate the obtained results.The effect of sojourn times in distinct regimes on the availability and the up time are also discussed in the numerical example. | Liying Wang Lirong Cui Mingli Yu | 2011 | Journal of Systems Engineering and Electronics2011，22，5： | 5 |
