Transient pressure analysis for the reactor core and containment of a HTGR after a primary loop pressure boundary break accident

The pressure variances in the reactor core and containment of a High Temperature Gas-cooled Reactor (HTGR) after a primary loop pressure boundary break accident determine the structural integrity and safety of the reactor. Based on mass conservation, energy conservation and state equations, explicit formulae for the transient pressure and temperature variances in the pressure vessels were deduced, and a set of differential equations for the transient pressure and temperature variances in the containment were developed. Numerical simulation was also conducted to investigate the transient pressure and temperature variances in the pressure vessels and containment. The results show that energy transformation due to expansion work cannot be neglected. The maximum pressure in the containment could increase by 40 percent due to blockage caused by air in the containment. Detailed numerical simulations of the transient pressure and temperature variance in the reactor core flow passages were also conducted. The results show that the pressures acting on the reactor core and containment are below acceptable values.     

气溶胶取样测试技术研究与实验验证

气溶胶过滤效率是衡量安全壳过滤排放系统性能的重要指标。以安全壳过滤排放系统的研制为背景，针对高温空气和水蒸汽混合介质条件下的固体粒子气溶胶取样及测试技术进行研究，解决了水蒸汽存在条件下气溶胶的取样测量中存在的问题，设计完成了一套可用于安全壳过滤排放系统气溶胶过滤效率检测的取样测试系统。通过多角度对比和实验分析，最终确定了采用疏水性聚四氟乙烯滤膜能够满足混合气体的采样需求。此外实验中发现滤膜的吸湿性和静电效应对测量的准确性影响较大，而采用滤膜恒重和使用铝箔纸的方法能有效解决该问题，提高测量的准确度。在此基础上，完成了取样测试回路的实验验证，并对结果进行了不确定度分析，证明了本套系统能够满足实验需求。     

基于优化模型的街面逃逸犯罪嫌疑人的围堵方案探讨

本文针对目前高发的“两抢一盗”街面犯罪及全国各省市地区警力资源不足的现状，提出两种基于优化模型的可用计算机编程实现的堵截方案，以实现快速有效的抓捕逃逸犯罪嫌疑人，由此提高公安机关打击街面犯罪的工作效率和破案能力。其中方案一采用的是具有实战价值的最优布控圈模型，适用于突发性的、社会影响恶劣的犯罪案件，确保能将犯罪嫌疑人第一时间围堵和抓捕。而方案二采用的是关键路布控追捕模型，能提高抓捕和破案效率的同时大大降低了对警力资源的需求，两个方案均具有实际意义。     

Dynamic spreading behavior of homogeneous and heterogeneous networks

The detailed investigation of the dynamic epidemic spreading on homogeneous and heterogeneous networks was carried out. After the analysis of the basic epidemic models, the susceptible-infected-susceptible (SIS) model on homogenous and heterogeneous networks is established, and the dynamical evolution of the density of the infected individuals in these two different kinds of networks is analyzed theoretically. It indicates that heterogeneous networks are easier to propagate for the epidemics and the leading spreading behavior is dictated by the exponential increasing in the initial outbreaks. Large-scale simulations display that the infection is much faster on heterogeneous networks than that on homogeneous ones. It means that the network topology can have a significant effect on the epidemics taking place on complex networks. Some containment strategies of epidemic outbreaks are presented according to the theoretical analyses and numerical simulations.     

遏止刑讯逼供的方法分析

刑讯逼供是一种丑恶的历史现象,在建立社会主义法治国家的进程中必须通过确立疑罪从无,辅以口供补强规则;改革现行刑事侦查体制,规范和控制侦查权利,加强对侦查的监督和制约;取消如实回答义务,赋予犯罪嫌疑人沉默权,确立不被强迫自证其罪规则;强调依法取证,确立非法取证的排除规则,建立法定证据制度;确立举证责任倒置原则;扩大律师在刑事诉讼中的作用;树立正确的执法理念等措施来加以遏制。
