In order to get useful data, it researches the network sniffing technology based on Raw Socket and mainly studies the technology of protocol analyze and data recombine. And it introduces the Trojan horse technique to the network data collection part, improves the process hiding technique, uses the triple-thread technique, and so on. It ensures the imperceptibility and stability of the network data collection part. Then this paper develops pseudo hypertext transfer protocol based on HTTP. This protocol is used in the communication between the network data collection part and the service part, which make the communication more covert.

研究基于Raw Socket的网络监听技术，为了能取到敏感数据，还对协议解析和数据重组技术做了详细研究；并在网络数据采集端引入了木马技术，对进程隐藏技术做了改进，采用三线程技术等，来保证网络数据采集端的隐蔽性和稳定性；接下来本文在分析HTTP协议的基础上设计开发了PHTTP协议，该协议用于网络数据采集端与服务端之间的数据通信，使通信更加隐蔽。

In winter, snow accumulates and melts fast in spring. Snowmelt flood and a summer flood display a double peak pattern of discharge route. In order to simulate the precipitation-runoff features in semi-arid regions, an Atmosphere-Vegetation Interaction model with detailed energy and water transfer processes between atmosphere, vegetation and soil was used.

由于这些特点，在地表水量平衡的计算和模拟中，蒸发的估算十分重要，为此在植被-大气相互作用模式中对水文过程作了改进，模式中包含了大气-植被-土壤间的能量和水分传输过程，特别是半干旱区地表蒸发和植被的蒸腾过程作了比较细致的处理，考虑了蓄满和超渗两种产流机制，同时采用了一个简化的雪盖模型。

Comparisons between the results from the wind tunnel tests, numerical simulations and the field tests were performed to verify the accuracy of the CFD method. Then the advanced k-ε turbulence model was used to compute the mean pressures on a long span curve shaped roof with the front door open or not open.
