| 2 | 5-21 A Large Area Plastic Scintillation Detector with 4-corner-readout显示文摘Large area plastic scintillation detectors are applied widely in modern physics labs due to the development of the time-of-flight technique. They are usually constructed with a module array design, such as the TOF Wall. The performance of such detectors is excellent, but the number of electronics channels is quite large, and the operation and calibration are too complicated. As a result, a large area plastic scintillation detector with only 4 readout signals from the corners is constructed and developed as a simple TOF Wall at ETF in IMP. | Tang Shuwen Yu Yuhong Zhou Yong Sun Zhiyu Zhang Xueheng Wang Shitao Yue Ke Liu Longxiang Fang Fang Yan Duo Sun Yu Wang Zhaomin | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 3 | Dispersive Order of Lifetimes of Series Systems in Multiple-Outlier Weibull Models显示文摘This paper considers the multiple-outlier Weibull model,and derives some sufficient conditions for the comparison of lifetimes of series systems with respect to dispersive order.In these models,order statistic is closed under minima,so convex transform,star and Lorenz orders are not investigated because they are scale variant.The results established here strengthen some of the results presented by Fang and Tang(2014). | FANG Longxiang BARMALZAN Ghobad LING Jie | 2016 | Journal of Systems Science & Complexity2016，29，6： | 0 |
| 4 | Optimal Grouping of Heterogeneous Components in Series and Parallel Systems Under Archimedean Copula Dependence显示文摘This paper considers series and parallel systems comprising n components drawn from a heterogeneous population consisting of m different subpopulations.The components within each subpopulation are assumed to be dependent,while the subpopulations are independent of each other.The authors also assume that the subpopulations have different Archimedean copulas for their dependence.Under this setup,the authors discuss the series and parallel systems reliability for three different cases,respectively.The authors use the theory of stochastic orders and majorization to establish the main results,and finally present some numerical examples to illustrate all the results established here. | FANG Longxiang ZHANG Xinsheng JIN Qing | 2022 | Journal of Systems Science & Complexity2022，35，3： | 0 |
| 5 | Residual Effect of Fipronil in Eriocheir sinensis显示文摘The residual effects of fipronil aqueous solutions(at mass concentrations of 10,30 and 50μg/L,respectively)on Eriocheir sinensis were investigated by the semi-static experiment method.The results showed that among the treatment groups with different mass concentrations,the high mass concentration group contained fipronil at a significantly higher content in the crab legs than the low-mass concentration group,and also a significantly higher content in the body than the low mass concentration group.There were no significant differences in the content of fipronil between different parts of E.sinensis.The trend of fipronil-enriched parts was from the legs to the body to the gonads.Fipronil residue in E.sinensis had no sex selectivity,but it enriched faster in female E.sinensis than males.This study provides a certain reference for dealing with related fishery pollution accidents. | Xi CHEN Cong ZHANG Chao SONG Longxiang FANG Xinyue DONG Jiazhang CHEN | 2020 | Agricultural Biotechnology2020，9，4： | 0 |
