环境规制政策与公共健康——基于环境污染的中介效应检验

为了探究环境规制政策对于环境污染及公共健康的影响,本文基于我国1978至2013年颁布的976条环境规制政策,利用从政策属性力度、政策内容力度两个维度对我国环境规制政策进行量化的数据,构建了针对环境规制政策效果的计量模型,通过将中介效应检验方法引入环境健康经济学分析,检验了环境污染对环境规制政策与公共健康的中介效应.研究结果表明:环境规制政策对公共健康具有促进作用;我国总体的环境规制政策对于防治环境污染产生了一定程度的积极效果;环境规制政策通过对环境污染显著的部分中介效应进而对公共健康产生了促进作用.本研究基于总体环境规制政策文献量化角度考察的"政策-环境-健康"三维动态关系结果,阐明了环境规制政策、环境污染以及公共健康三者的影响传输路径,对于有效评估环境规制政策效果,保障环境质量以及公共健康的可持续提升具有理论借鉴价值.     

适用于混沌密钥分发的新误码协调方法

对于现有的密钥分发中的误码协调方法的复杂性和多次传输的问题，使用倒三角类坐标定位法来解决。将所得裸钥放置于下三角矩阵中，三边分别进行奇偶比较并互相传输计算结果，以达到定位错误比特位的目的。使用互注入光反馈激光器产生相关性高的混沌态来提取裸钥，通过该协调方法，最终可以达到10－8～10－10量级的误码率。通过该方法可以简单、有效地删除裸钥中的误码，满足现实通信对误码率的容忍度。     

基于交通信号灯信息的混合动力汽车节能预测控制方法

针对传统混合动力汽车控制方法不考虑已知道路交通信号灯信息对车辆能量管理影响的问题,提出了基于交通信号灯信息的混合动力汽车节能预测控制智能优化策略。通过建立混合动力汽车系统的简化模型,并采用连续广义最小残量方法求解模型预测控制问题。运用MATLAB/Simulink进行仿真,仿真结果验证了交通信号灯信息模型的有效性,以及所设计的模型预测控制算法大幅度提高混合动力汽车的燃油经济性的能力和实时控制性能。研究结果表明所提出的控制策略可以实现车辆行驶轨迹的优化控制,显著提高了车辆的燃油经济性,并满足系统的实时最优控制要求。

Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.
