| 1 | 3D printing of bone tissue engineering scaffolds显示文摘Tissue engineering is promising in realizing successful treatments of human body tissue loss that current methods cannot treat well or achieve satisfactory clinical outcomes.In scaffold-based bone tissue engineering,a high performance scaffold underpins the success of a bone tissue engineering strategy and a major direction in the field is to produce bone tissue engineering scaffolds with desirable shape,structural,physical,chemical and biological features for enhanced biological performance and for regenerating complex bone tissues.Three-dimensional(3D)printing can produce customized scaffolds that are highly desirable for bone tissue engineering.The enormous interest in 3D printing and 3D printed objects by the science,engineering and medical communities has led to various developments of the 3D printing technology and wide investigations of 3D printed products in many industries,including biomedical engineering,over the past decade.It is now possible to create novel bone tissue engineering scaffolds with customized shape,architecture,favorable macro-micro structure,wettability,mechanical strength and cellular responses.This article provides a concise review of recent advances in the R&D of 3D printing of bone tissue engineering scaffolds.It also presents our philosophy and research in the designing and fabrication of bone tissue engineering scaffolds through 3D printing. | Chong Wang Wei Huang Yu Zhou Libing He Zhi He Ziling Chen Xiao He Shuo Tian Jiaming Liao Bingheng Lu Yen Wei Min Wang | 2020 | Bioactive Materials2020，5，1： | 20 |
| 2 | Transmission Network Expansion Planning Considering Uncertainties in Loads and Renewable Energy Resources显示文摘This paper proposes a novel method for transmission network expansion planning(TNEP)that take into account uncertainties in loads and renewable energy resources.The goal of TNEP is to minimize the expansion cost of candidate lines without any load curtailment.A robust linear optimization algorithm is adopted to minimize the load curtailment with uncertainties considered under feasible expansion costs.Hence,the optimal planning scheme obtained through an iterative process would be to serve loads and provide a sufficient margin for renewable energy integration.In this paper,two uncertainty budget parameters are introduced in the optimization process to limit the considered variation ranges for both the load and the renewable generation.Simulation results obtained from two test systems indicate that the uncertainty budget parameters used to describe uncertainties are essential to arrive at a compromise for the robustness and optimality,and hence,offer a range of preferences to power system planners and decision makers. | Jinyu Wen Xingning Han Jiaming Li Yan Chen Haiqiong Yi Chang Lu | 2015 | CSEE Journal of Power and Energy Systems2015，1，1： | 17 |
| 3 | Wnt and BMP signaling crosstalk in regulating dental stem cells:Implications in dental tissue engineering显示文摘Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling.Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance,essential oral functions and the quality of life.Regenerative dentistry holds great promise in treating oral/dental disorders.The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells,along with the signaling mechanisms governing stem cell self-renewal and differentiation.In this review,we first summarize the biological characteristics of seven types of dental stem cells,including dental pulp stem cells,stem cells from apical papilla,stem cells from human exfoliated deciduous teeth,dental follicle precursor cells,periodontal ligament stem cells,alveolar bone-derived mesenchymal stem cells(MSCs),and MSCs from gingiva.We then focus on how these stem cells are regulated by bone morphogenetic protein(BMP)and/or Wnt signaling by examining the interplays between these pathways.Lastly,we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways.We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications.Thus,we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade. | Fugui Zhang Jinlin Song Hongmei Zhang Enyi Huang Dongzhe Song Viktor Tollemar Jing Wang Jinhua Wang Maryam Mohammed Qiang Wei Jiaming Fan Junyi Liao Yulong Zou Feng Liu Xue Hu Xiangyang Qu Liqun Chen Xinyi Yu Hue H.Luu Michael J.Lee Tong-Chuan He Ping Ji | 2016 | Genes & Diseases2016，3，4： | 16 |

| 5 | Geochronology, Geochemistry and Sr-Nd-Pb-Hf Isotopes of No. I Complex from the Shitoukengde Ni–Cu Sulfide Deposit in the Eastern Kunlun Orogen, Western China: Implications for the Magmatic Source, Geodynamic Setting and Genesis显示文摘The Shitoukengde Ni-Cu deposit, located in the Eastern Kunlun Orogen, comprises three mafic–ultramafic complexes, with the No. I complex hosting six Ni-Cu orebodies found recently. The deposit is hosted in the small ultramafic bodies intruding Proterozoic metamorphic rocks. Complexes at Shitoukengde contain all kinds of mafic-ultramafic rocks, and olivine websterite and pyroxene peridotite are the most important Ni-Cu-hosted rocks. Zircon U-Pb dating suggests that the Shitoukengde Ni-Cu deposit formed in late Silurian(426–422 Ma), and their zircons have εHf(t) values of-9.4 to 5.9 with the older T_(DM1) ages(0.80–1.42 Ga). Mafic-ultramafic rocks from the No. I complex show the similar rare earth and trace element patterns, which are enriched in light rare earth elements and large ion lithophile elements(e.g., K, Rb, Th) and depleted in heavy rare earth elements and high field strength elements(e.g., Ta, Nb, Zr, Ti). Sulfides from the deposit have the slightly higher δ^(34)S values of 1.9–4.3‰ than the mantle(0 ± 2‰). The major and trace element characteristics, and Sr-Nd-Pb and Hf, S isotopes indicate that their parental magmas originated from a metasomatised, asthenospheric mantle source which had previously been modified by subduction-related fluids, and experienced significant crustal contamination both in the magma chamber and during ascent triggering S oversaturation by addition of S and Si, that resulted in the deposition and enrichment of sulfides. Combined with the tectonic evolution, we suggest that the Shitoukengde Ni-Cu deposit formed in the post-collisional, extensional regime related to the subducted oceanic slab break-off after the Wanbaogou oceanic basalt plateau collaged northward to the Qaidam Block in late Silurian. | LI Liang SUN Fengyue LI Bile LI Shijin CHEN Guangjun WANG Wei YAN Jiaming ZHAO Tuofei DONG Jun ZHANG Dexin | 2018 | Acta Geologica Sinica(English Edition)2018，92，1： | 10 |
| 6 | Alendronate loaded graphene oxide functionalized collagen sponge for the dual effects of osteogenesis and anti-osteoclastogenesis in osteoporotic rats显示文摘Graphene Oxide(GO)-related hydrogels have been extensively studied in hard tissue repair,because GO can not only enhance the mechanical properties of polymers but also promote osteogenic differentiation of mesenchymal stem cells.However,simple GO-related hydrogels are not ideal for the repair of osteoporotic bone defects as the overactive osteoclasts in osteoporosis.Alendronate(Aln)is known to inhibit osteoclasts and may bind to GO through covalent connection.Therefore,delivering Aln in GO-related hydrogels may be effective to repair osteoporotic bone defects.Here,we developed a control-released system which is constructed by collagen(Col)-GO sponges loaded with Aln(Col-GO-Aln)for osteoporotic bone defect repair.In vitro,Col-GO-Aln sponges prolonged the release period of Aln,and the sponge containing 0.05%(w/v)GO released Aln faster than sponge with 0.2%GO.Furthermore,tartrate-resistant acid phosphatase(TRAP)and F-actin staining demonstrated that Col-GO-Aln sponges effectively inhibited osteoclastogenesis of monocyte-macrophages.In vivo,micro-CT scan showed that the volume of newborn bone in defect site by 0.05%GO sponge was nearly three times larger than that of other groups.Moreover,the CT and histological examinations of rat femur proved that Col-GO-Aln sponges decreased the number of osteoclasts and suppressed the systemic bone loss in osteoporotic rats.These findings reveal that the application of GO as carriers of anti-osteoporosis drugs is a viable treatment for osteoporosis.The results also underscore the potential of GO-related hydrogels with Aln-releasing capacity for bone regeneration in osteoporosis. | Yuyang Zeng Muran Zhou Lifeng Chen Huimin Fang Shaokai Liu Chuchao Zhou Jiaming Sun Zhenxing Wang | 2020 | Bioactive Materials2020，5，4： | 10 |
| 7 | Influences of preload on the friction and wear properties of high-speed instrument angular contact ball bearings显示文摘For starved-oil or solid lubrication of high-speed instrument angular contact ball bearings, friction heating and wear are the main reasons of bearing failures. This paper presents a dynamic wear simulation model to investigate the impacts of different preload methods and the changes of preload caused by wear on bearing wear life. The integral value QV of stress and sliding velocity in the contact ellipses between a ball and the inner and outer races determines friction heating and wear. The changes of QV with the friction coefficient and the wear volume under constantforce preload and fixed-position preload are analyzed. Results show that under the same initial preload, the QV decreases with an increase of the friction coefficient for both preload methods, and the latter is slightly larger. The wear of the ball and the race is equivalent to the ball diameter reduction.The QV of constant-force preload is almost not changed with a decrease of the ball diameter, but for fixed-position preload, the value decreases firstly and then increases substantially due to insufficient preload, and slipping occurs, the ball diameter is reduced by 0.025%, while the preload is reduced by 60.33%. An estimation of the bearing wear life under different preload methods requires a consideration of the changes in the wear rate of bearing parts. | Tao ZHANG Xiaoyang CHEN Jiaming GU Zhengliang WANG | 2018 | Chinese Journal of Aeronautics2018，31，3： | 9 |
| 8 | Deep-learning-enabled dual-frequency composite fringe projection profilometry for single-shot absolute 3D shape measurement显示文摘Single-shot high-speed 3D imaging is important for reconstructions of dynamic objects.For fringe projection profilometry(FPP),however,it is still challenging to recover accurate 3D shapes of isolated objects by a single fringe image.In this paper,we demonstrate that the deep neural networks can be trained to directly recover the absolute phase from a unique fringe image that involves spatially multiplexed fringe patterns of different frequencies.The extracted phase is free from spectrum-aliasing problem which is hard to avoid for traditional spatial-multiplexing methods.Experiments on both static and dynamic scenes show that the proposed approach is robust to object motion and can obtain high-quality 3D reconstructions of isolated objects within a single fringe image. | Yixuan Li Jiaming Qian Shijie Feng Qian Chen Chao Zuo | 2022 | Opto-Electronic Advances2022，5，5： | 8 |
| 9 | Tumor-expressed B7-H3 mediates the inhibition of antitumor T-cell functions in ovarian cancer insensitive to PD-1 blockade therapy显示文摘Although PD-L1/PD-1 blockade therapy has been approved to treat many types of cancers,the majority of patients with solid tumors do not respond well,but the underlying reason remains unclear.Here,we studied ovarian cancer(OvCa),a tumor type generally resistant to current immunotherapies,to investigate PD-1-independent immunosuppression.We found that PD-L1 was not highly expressed in the tumor microenvironment(TME)of human OvCa.Instead,B7-H3,another checkpoint molecule,was highly expressed by both tumor cells and tumor-infiltrating antigen-presenting cells(APCs),which correlated with T-cell exhaustion in patients.Using ID8 OvCa mouse models,we found that B7-H3 expressed on tumor cells,but not host cells,had a dominant role in suppressing antitumor immunity.Therapeutically,B7-H3 blockade,but not PD-1 blockade,prolonged the survival of ID8 tumorbearing mice.Collectively,our results demonstrate that tumor-expressed B7-H3 inhibits the function of CD8^(+)T cells and suggest that B7-H3 may be a target in patients who are not responsive to PD-L1/PD-1 inhibition,particularly OvCa patients. | Dongli Cai Jiaming Li Dingfeng Liu Shanjuan Hong Qin Qiao Qinli Sun Pingping Li Nanan Lyu Tiantian Sun Shan Xie Li Guo Ling Ni Liping Jin Chen Dong | 2020 | Cellular & Molecular Immunology2020，17，3： | 8 |
| 10 | Industrial Spatial Agglomeration Using Distance-based Approach in Beijing, China显示文摘To study the difference of industrial location among different industries, this article is to test the spatial agglomeration across industries and firm sizes at the city level. Our research bases on a unique plant-level data set of Beijing and employs a distance-based approach, which considers space as continuous. Unlike previous studies, we set two sets of references for service and manufacturing industries respectively to adapt to the investigation in the intra-urban area. Comparing among eight types of industries and different firm sizes, we find that: 1) producer service, high-tech industries and labor-intensive manufacturing industries are more likely to cluster, whereas personal service and capital-intensive industries tend to be randomly dispersed in Beijing; 2) the spillover of the co-location of firms is more important to knowledge-intensive industries and has more significant impact on their allocation than business-oriented services in the intra-urban area; 3) the spatial agglomeration of service industries are driven by larger establishments, whereas manufacturing industries are mixed. | LI Jiaming ZHANG Wenzhong YU Jianhui CHEN Hongxia | 2015 | Chinese Geographical Science2015，25，6： | 7 |
| 11 | Top-emitting thermally activated delayed fluorescence organic light-emitting devices with weak light-matter coupling显示文摘Resonance interaction between a molecular transition and a confined electromagnetic field can lead to weak or strong light-matter coupling.Considering the substantial exciton–phonon coupling in thermally activated delayed fluorescence(TADF)materials,it is thus interesting to explore whether weak light-matter coupling can be used to redistribute optical density of states and to change the rate of radiative decay.Here,we demonstrate that the emission distribution of TADF emitters can be reshaped and narrowed in a top-emitting organic light-emitting device(OLED)with a weakly coupled microcavity.The Purcell effect of weak microcavity is found to be different for TADF emitters with different molecular orientations.We demonstrate that radiative rates of the TADF emitters with vertical orientation can be substantial increased in weakly coupled organic microcavity.These observations can enhance external quantum efficiencies,reduce efficiency roll-off,and improve color-purities of TADF OLEDs,especially for emitters without highly horizontal orientation. | Chunxiu Zang Shihao Liu Mengxin Xu Ruifang Wang Chen Cao Zelin Zhu Jiaming Zhang Hui Wang Letian Zhang Wenfa Xie Chun-Sing Lee | 2021 | Light(Science & Applications)2021，10，7： | 7 |
| 12 | Deep learning in optical metrology:a review显示文摘With the advances in scientific foundations and technological implementations,optical metrology has become versatile problem-solving backbones in manufacturing,fundamental research,and engineering applications,such as quality control,nondestructive testing,experimental mechanics,and biomedicine.In recent years,deep learning,a subfield of machine learning,is emerging as a powerful tool to address problems by learning from data,largely driven by the availability of massive datasets,enhanced computational power,fast data storage,and novel training algorithms for the deep neural network.It is currently promoting increased interests and gaining extensive attention for its utilization in the field of optical metrology.Unlike the traditional,,physics-basedH approach,deep-learning-enabled optical metrology is a kind of,/data-drivenw approach,which has already provided numerous alternative solutions to many challenging problems in this field with better performances.In this review,we present an overview of the current status and the latest progress of deep-learning technologies in the field of optical metrology.We first briefly introduce both traditional image-processing algorithms in optical metrology and the basic concepts of deep learning,followed by a comprehensive review of its applications in various optical metrology tasks,such as fringe denoising,phase retrieval,phase unwrapping,subset correlation,and error compensation.The open challenges faced by the current deep-learning approach in optical metrology are then discussed.Finally,the directions for future research are outlined. | Chao Zuo Jiaming Qian Shijie Feng Wei Yin Yixuan Li Pengfei Fan Jing Han Kemao Qian Qian Chen | 2022 | Light(Science & Applications)2022，11，4： | 7 |
| 13 | Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment显示文摘Variation of maternal gut microbiota may increase the risk of autism spectrum disorders(ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother–child pairs of ASD children and 30 matched mother–child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother–child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation. | Ning Li Junjie Yang Jiaming Zhang Cheng Liang Ying Wang Bin Chen Changying Zhao Jingwen Wang Guangye Zhang Dongmei Zhao Yi Liu Lehai Zhang Jun Yang Guimei Li Zhongtao Gai Lei Zhang Guoping Zhao | 2019 | Genomics, Proteomics & Bioinformatics2019，17，1： | 6 |

| 15 | Ferroptosis as a novel form of regulated cell death:Implications in the pathogenesis,oncometabolism and treatment of human cancer显示文摘The treatment of cancer mainly involves surgical excision supplemented by radiotherapy and chemotherapy.Chemotherapy drugs act by interfering with tumor growth and inducing the death of cancer cells.Anti-tumor drugs were developed to induce apoptosis,but some patient’s show apoptosis escape and chemotherapy resistance.Therefore,other forms of cell death that can overcome the resistance of tumor cells are important in the context of cancer treatment.Ferroptosis is a newly discovered iron-dependent,non-apoptotic type of cell death that is highly negatively correlated with cancer development.Ferroptosis is mainly caused by the abnormal increase in iron-dependent lipid reactive oxygen species and the imbalance of redox homeostasis.This review summarizes the progression and regulatory mechanism of ferroptosis in cancer and discusses its possible clinical applications in cancer diagnosis and treatment. | Feifei Pu Fengxia Chen Zhicai Zhang Deyao Shi Binlong Zhong Xiao Lv Andrew Blake Tucker Jiaming Fan Alexander J.Li Kevin Qin Daniel Hu Connie Chen Hao Wang Fang He Na Ni Linjuan Huang Qing Liu William Wagstaff Hue H.Luu Rex C.Haydon Le Shen Tong-Chuan He Jianxiang Liu Zengwu Shao | 2022 | Genes & Diseases2022，9，2： | 6 |

| 17 | Friction moment analysis of space gyroscope bearing with ribbon cage under ultra-low oscillatory motion显示文摘This paper presents the model of calculating the total friction moment of space gyroscope ball bearings which usually work under ultra-low oscillatory motion and are very sensitive to the friction moment. The aim is to know the proportion of the friction moment caused by each frictional source in the bearing's total friction moment, which is helpful to optimize the bearing design to deduce the friction moment. In the model, the cage dynamic equations considering six degree-of-freedom and the balls dynamic equations considering two degree-of-freedom were solved.The good trends with different loads between the measured friction moments and computational results prove that the model under constant rate was validated. The computational results show that when the speed was set at 5 r/min, the bearing's maximum total friction moment when oscillation occurred was obviously larger than that occurred at a constant rate. At the onset of each oscillatory motion, the proportion of the friction moment caused by cage in the bearing's total friction moment was very high, and it increased with the increasing speed. The analyses of different cage thicknesses and different clearances between cage pocket and ball show that smaller thickness and clearance were preferred. | Jiang Shaona Chen Xiaoyang Gu Jiaming Shen Xuejin | 2014 | Chinese Journal of Aeronautics2014，27，5： | 5 |
| 18 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 19 | Autophagy enhanced by curcumin ameliorates inflammation in atherogenesis via the TFEB-P300-BRD4 axis显示文摘Disturbance of macrophage-associated lipid metabolism plays a key role in atherosclerosis.Crosstalk between autophagy deficiency and inflammation response in foam cells(FCs) through epigenetic regulation is still poorly understood. Here, we demonstrate that in macrophages, oxidized lowdensity lipoprotein(ox-LDL) leads to abnormal crosstalk between autophagy and inflammation,thereby causing aberrant lipid metabolism mediated through a dysfunctional transcription factor EB (TFEB)-P300-bromodomain-containing protein 4(BRD4) axis. ox-LDL led to macrophage autophagy deficiency along with TFEB cytoplasmic accumulation and increased reactive oxygen species generation. This activated P300 promoted BRD4 binding on the promoter regions of inflammatory genes, consequently contributing to inflammation with atherogenesis. Particularly, ox-LDL activated BRD4-dependent super-enhancer associated with liquid-liquid phase separation(LLPS) on the regulatory regions of inflammatory genes. Curcumin(Cur) prominently restored FCs autophagy by promoting TFEB nuclear translocation, optimizing lipid catabolism, and reducing inflammation. The consequences of P300 and BRD4 on super-enhancer formation and inflammatory response in FCs could be prevented by Cur. Furthermore, the anti-atherogenesis effect of Cur was inhibited by macrophage-specific Brd4 overexpression or Tfeb knock-out in Apoe knock-out mice via bone marrow transplantation. The findings identify a novel TFEB-P300-BRD4 axis and establish a new epigenetic paradigm by which Cur regulates autophagy, inhibits inflammation, and decreases lipid content. | Xuesong Li Ruigong Zhu Hong Jiang Quanwen Yin Jiaming Gu Jiajing Chen Xian Ji Xuan Wu Haiping Fu Hui Wang Xin Tang Yuanqing Gao Bingjian Wang Yong Ji Hongshan Chen | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 4 |
| 20 | Weapon configuration, allocation and route planning with time windows for multiple unmanned combat air vehicles显示文摘Unmanned combat air vehicles(UCAVs) mission planning is a fairly complicated global optimum problem. Military attack missions often employ a fleet of UCAVs equipped with weapons to attack a set of known targets. A UCAV can carry different weapons to accomplish different combat missions. Choice of different weapons will have different effects on the final combat effectiveness. This work presents a mixed integer programming model for simultaneous weapon configuration and route planning of UCAVs, which solves the problem optimally using the IBM ILOG CPLEX optimizer for simple missions. This paper develops a heuristic algorithm to handle the medium-scale and large-scale problems. The experiments demonstrate the performance of the heuristic algorithm in solving the medium scale and large scale problems. Moreover, we give suggestions on how to select the most appropriate algorithm to solve different scale problems. | ZHANG Jiaming LIU Zhong SHI Jianmai CHEN Chao | 2018 | Journal of Systems Engineering and Electronics2018，29，5： | 4 |
