为了提高强横风作用下客运列车运行的稳定性，基于三维非定常方程，采用动网格技术，对强横风作用下的青藏线客运列车在路堤上运行情况进行了模拟，分析车速、风速及路堤高度与气动力之间的关系，并将计算结果与风洞实验结果进行对比。

The influence laws of the unified strength theory parameters and strain softening characteristic parameters on the tunnel tangential stress are discussed.

研究结果表明，统一强度理论参数和软化特性参数对衬砌与围岩塑性区切向应力的影响显著。

As the environment parameters change, the codes which are the Bragg wavelengths of the FBGs accordingly change in the same time and in the same location, so as to increase the system capability, realize the measurement of temperature stress and pressure for special engineering (such as oil tank, power station, tunnel) in a way of distributing measurement.

利用编码式光纤光栅的布拉格波长对待测对象的位置和温度、应力、应变等进行编码，当待测对象的环境参量发生变化时，与之对应的编码，即编码式光纤光栅的布拉格波长随之同时同点发生变化，借以提高传感系统的容量，实现对特定对象(如油罐、油气管道、高压变电站等)的温度以及应力、应变等的准分布式定点测量。

Focused on different nose figures used in the s haped charge warhead and the target discrimination unit on side wall, the model was computed by CFD and tested by wind tunnel facilities.

针对带药型罩子弹药可能使用的头部外形，对子弹药简化模型进行了CFD计算和风洞测试。
