In this study, the CPE processes of four different kinds of polyaromatic hydrocarbons, acenaphthene, anthracene, phenanthrene and pyrene, with two kinds of silicone surfactants, DC-193 and DC-190, were studied separately, and four different assisting methods for the phase separation of the CPE process including heating at a higher temperature, adding salts, centrifugation and stirring were introduced, respectively.

今利用两种聚醚型有机硅表面活性剂DC-193和DC-190，对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究，分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。通过测定表面活性剂富集相的体积百分率Vs/随时间的变化和最终的萃取率，研究上述四种不同辅助方法对相分离行为和萃取性能的影响。

One is reminded of Montaigne's acerbic comment:"Men under stress are fools, and fool themselves." Certainly the Wildfire team was under severe stress, but they were also prepared to make mistakes.

有一个提醒Montaigne的尖刻评论："男人在压力下是傻子，真正的傻子"，当然，Wildfire队顶着强大的压力，但他们也随时会犯错误。

The network-torpedo can realize real time identification, pursuit and attack on target with the information obtained effectively from battlefield at any time. We put emphasis on the functions and principles of several key technologies, including acoustic communication system, satellite navigation location system and power system. Finally, we propose some applied ideas for the network-torpedo.

展示了网络鱼雷以其能随时高效获取战场环境信息来实现对目标的实时识别、跟踪和攻击，并着重从功能及原理上对水声通信系统、卫星导航定位系统及动力系统这几项关键技术进行了较详细的论述，最后提出了网络鱼雷的作战应用设想，展望了其应用前景。

This paper was focus on Dianshan River which is one of the most important water sources of Shanghai. We study the distribution, speciation and transformation rule of Cu, Cd, Cr, Hg, Pb and As in sedimentary record. In addition, the history of development of industries and agriculture were also taken into account to study the heavy metal pollution history in the study area.

本文以上海的重要水源地——淀山湖为研究对象，通过对研究区沉积物中重金属元素Cu、Cd、Cr、Hg、Pb、As的时空分布规律以及它们在沉积物中随时间或沉积深度的形态分布及迁移转化规律的研究，综合考虑区域工农业发展现状和历史对沉积物中重金属元素含量及分布的影响，对区域重金属污染历史及效应进行分析论证。
