| 1 | Age-related Changes of Carbon Accumulation and Allocation in Plants and Soil of Black Locust Forest on Loess Plateau in Ansai County, Shaanxi Province of China显示文摘在高原生态系统吸引了的瓷器黄土的碳(C) 隐遁上的重新造林的效果很在最近的年里研究注意。黑蝗虫树(Robinia pseudoacacia L.) 在重新造林和水和土壤保存努力为他们的重要使用被珍视。这种森林类型越过黄土高原是普遍的,并且一定是任何在这个易碎的生态的区域为 C 隐遁努力计划的一个必要部件。在重新造林仍然保持不明确以后,看台的长期的效果在 C 累积和分配上变老。我们在黄土高原上检验了黑蝗虫森林(后来种的 5, 9, 20, 30, 38,和 56 年) 的年龄顺序在植物(树,灌木,牧草,和叶垃圾) 和土壤(0100 厘米) 评估 C 累积和分配。Allometric 方程为估计树部件的生物资源被开发(叶,树枝,茎没有吠叫,吠叫并且根) 与一个破坏采样方法。我们的结果证明那个黑蝗虫森林生态系统常常积累了 C,从 31.42 Mg C/ 哈(1 Mg = 10 < 啜 class= “ a-plus-plus ” > 6 g ) 在到在 38 年的 79.44 Mg C/ha 的 5 年。在旧森林阶段(38 ~ 56 年) ,在植物生物资源的 C 的数量显著地减少了(从 45.32 ~ 34.52 Mg C/ha ) 由于树的高死亡。然而,旧森林能在土壤连续地积累 C (从 33.66 ~ 41.00 Mg C/ha ) 。在灌木生物资源的 C 与看台年龄增加了,当在牧草层和叶垃圾的 C 股票是年龄无关的时。重新造林在森林土壤导致了 C 重新分配。C 存货与看台年龄常常增加了的表层土(020 厘米) 。然而,在 2030, 3050, 50100,和 20100 厘米层,在亚顶土壤的 C 存储是年龄无关的。这些结果建议作为一个时间的因素,继任在植被在地区性的 C 动力学在黑蝗虫森林里并且也在 C 累积和重新分配起一个关键作用。 | LI Taijun LIU Guobin | 2014 | Chinese Geographical Science2014，24，4： | 11 |
| 2 | Simultaneous determination of indapamide,perindopril and perindoprilat in human plasma or whole blood by UPLC-MS/MS and its pharmacokinetic application显示文摘Simple and sensitive methods were developed for the determination of indapamide, perindopril and its active metabolite perindoprilat in human plasma or whole blood by hyphenated ultra-performance liquid chromatography-mass spectrometry(UPLC-MS/MS). Indapamide-d3, perindopril-d4 and perindoprilat-d4 were used as the internal standards. The separation was performed on a Thermo BDS Hypersil C_(18) column(4.6 mm×100 mm, 2.4 mm) for indapamide and perindopril simultaneously following a protein precipitation pretreatment of the biosamples. The separation of perindoprilat was achieved independently on a phenomenex PFP column(4.6 mm×150 mm, 5 mm). All the analytes were quantitated with positive electrospray ionization and multiple reactions monitoring mode. The assay exhibited a linear range of 1–250 ng/mL for indapamide, 0.4–100 ng/mL for perindopril and 0.2–20 ng/mL for perindoprilat. The methods were fully validated to meet the requirements for bioassay in accuracy, precision,recovery, reproducibility, stabilities and matrix effects, and successfully applied to the pharmacokinetic study of perindopril tert-butylamine/indapamide compound tablets in Chinese healthy volunteers and the comparative pharmacokinetic study between plasma and whole blood. | Yi Tao Sheng Wang Lei Wang Min Song Taijun Hang | 2018 | Journal of Pharmaceutical Analysis2018，8，5： | 5 |
| 3 | DYNAMIC BEHAVIORAL MODELING FOR STRONGLY NONLINEAR DOHERTY PAS USING REAL-VALUED TIME-DELAY RECURRENT RBF MODEL显示文摘This paper proposes a Real-Valued Time-Delay Recurrent Radial Basis Function (RVTDRRBF) model suitable for dynamic modeling of the strongly nonlinear behaviors of the Doherty Power Amplifiers (DPAs). This model has four Tapped Delay Lines (TDLs), which account for the memory effect of the DPA. The structure of the RVTDRRBF model is simpler than the traditional FeedForward Neural Networks (FFNNs) model. Weights and centers of the proposed model can be resolved by the Orthogonal Least Square (OLS) and Singular Value De-composition (SVD) algorithm. A three-carrier Wideband Code Division Multiple Access (WCDMA) signal is taken as the test signal. The simulation results in frequency-domain and time-domain for a DPA with 51 dBm output illustrate a good agreement between the RVTDRRBF model and measurement data. Moreover, comparing the Normalized Mean Square Error (NMSE) of RVTDRRBF model, memory polynomial model and RVTDRBF model, it can be noticed that the proposed RVTDRRBF model is more accurate than the RVTDRBF model and the memory polynomial model in modeling the strong dynamic nonlinearity of the DPAs. | Hui Ming Liu Taijun Ye Yan Zhang Haili Shen Dongya Li Liang | 2012 | Journal of Electronics(China)2012，29，1： | 4 |
| 4 | Analysis of bacitracin and its related substances by liquid chromatography tandem mass spectrometry显示文摘A suitable liquid chromatography quadrupole time-of-flight mass spectrometric(LC–Q-TOF–MS) method was developed for separation and characterization of related substances in bacitracin test drug. The separation was performed on Li Chrospher RP-18 column using methanol as mobile phase A and 0.2% ammonium acetate buffer solution as mobile phase B in gradient elution. A total of 12 related substances were detected through high resolution mass spectrometric determination in a positive electrospray ionization mode. They were identified as co-existing active components and degradation products of bacitracin through the analysis and elucidation of both the protonated parents and the product ions of all the related substances and their fragmentation pathways were also proposed. | Suleiman Ahmed Suleiman Fan Song Mengxiang Su Taijun Hang Min Song | 2017 | Journal of Pharmaceutical Analysis2017，7，1： | 3 |
| 5 | Optimal regenerative repair of large segmental bone defect in a goat model with osteoinductive calcium phosphate bioceramic implants显示文摘So far,how to achieve the optimal regenerative repair of large load-bearing bone defects using artificial bone grafts is a huge challenge in clinic.In this study,a strategy of combining osteoinductive biphasic calcium phosphate(BCP)bioceramic scaffolds with intramedullary nail fixation for creating stable osteogenic microenvironment was applied to repair large segmental bone defects(3.0 cm in length)in goat femur model.The material characterization results showed that the BCP scaffold had the initial compressive strength of over 2.0 MPa,and total porosity of 84%.The cell culture experiments demonstrated that the scaffold had the excellent ability to promote the proliferation and osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells(BMSCs).The in vivo results showed that the intramedullary nail fixation maintained the initial stability and structural integrity of the implants at early stage,promoting the osteogenic process both guided and induced by the BCP scaffolds.At 9 months postoperatively,good integration between the implants and host bone was observed,and a large amount of newborn bones formed,accompanying with the degradation of the material.At 18 months postoperatively,almost the complete new bone substitution in the defect area was achieved.The maximum bending strength of the repaired bone defects reached to the 100% of normal femur at 18 months post-surgery.Our results demonstrated the good potential of osteoinductive BCP bioceramics in the regenerative repair of large load-bearing bone defects.The current study could provide an effective method to treat the clinical large segmental bone defects. | Wei Zhi Xiaohua Wang Dong Sun Taijun Chen Bo Yuan Xiangfeng Li Xuening Chen Jianxin Wang Zhao Xie Xiangdong Zhu Kai Zhang Xingdong Zhang | 2022 | Bioactive Materials2022，7，5： | 3 |

| 15 | INDEPENDENTLY-TUNED CONCURRENT DUAL-BAND BRANCH-LINE COUPLER USING VARACTOR显示文摘This paper presents a concurrent dual-band branch-line coupler with an independently tunable center frequency. In the proposed architecture, the quarter-wavelength lines, which work at two separated bands concurrently and can be tuned in one of them, are key components. Based on the analysis of ABCD-matrix, a novel hybrid structure and a pair of varactors topology are utilized to achieve concurrent dual-band operation and independent tunability, respectively. Using this configuration, it is convenient to tune the center frequency of the upper band, while the responses of the lower band remain unaltered. To verify the proposed idea, a demonstration is implemented and the simulated results are presented. | Guo Xiaofeng Ye Yan Liu Taijun Xu Qian Li Ruiyang | 2014 | Journal of Electronics(China)2014，31，4： | 1 |

| 17 | PERFORMANCE IMPROVEMENT FOR A WCDMA RADIO OVER FIBER SYSTEM USING DIGITAL PRE-DISTORTER显示文摘In this paper,a Radio Over Fiber (ROF) system with a Digital Pre-Distorter (DPD) for WCDMA signal transmission is investigated.A Look-Up Table (LUT) based DPD and a Memory Polynomial (MP) DPD are applied in the ROF link so as to suppress the out-of-band spurious spectrum and improve the transmission performance.The experimental results show that the out-of-band emission due to existence of the third-order Inter-Modulation Distortion (IMD3) is obviously sup-pressed by these two DPD.An Adjacent Channel Power Ratio (ACPR) improvement of 8 dB is ob-tained for a single-carrier WCDMA signal transmission.These two DPD have equal ability in lin-earization of the ROF system for a three-carrier WCDMA signal transmission.There is no apparent memory effects exist in the ROF link. | Ying Xiangyue Xu Tiefeng Liu Taijun Nie Qiuhua | 2012 | Journal of Electronics(China)2012，29，1： | 1 |
