The cutoff frequency of heteromophic waveguide in special structure is solved with the matching of electric and magnetic field on the invented boundary by vector partial differen-tial operator theory.

该文用矢量偏微分算子理论通过虚拟边界的电场和磁场的匹配求解特殊结构的异形波导的截止频率，这一方法可以精确而方便地求出几乎所有模式的截止频率。

Then the particle swarm optimization is introduced to collision detection area. In this dissertation, it also proposes two novel framework which combines the exist techniques of hierarchy bounding volume and surface simplification with the PSO. We have tested the frameworks in our "Haptic Interactive System ". The new frameworks performance well for most models in virtual scene.

本文探索和研究了虚拟环境中广泛使用的碰撞检测算法，尝试把几何模型的碰撞检测问题转化为优化搜索问题，把粒子群优化搜索技术引入碰撞检测领域，并结合碰撞检测领域现有的层次包围盒技术和网格简化技术，组成新颖的限时干涉检测算法框架，即用户可以方便地控制分配给碰撞检测算法的时间，尝试去克服这一技术瓶颈。

Current, shanghai has hit a network bawdy pornography content formed a series of lasting effect mechanisms, in the public security on website of whole town key, net complex place established a net to go up " call the police police box ", and cloth set fictitious network police " flatly "," An An ", begin a net to go up to patrol publicly be on duty.

现在，上海市已经就打击网络淫秽色情内容形成了一系列长效机制，在全市重点网站、网上治安复杂场所设立了网上"报警岗亭"，并布设了虚拟网络警察"平平"、"安安"，开展网上公开巡逻执勤。【以下内容为IT者网站提供英文翻译，未经授权请勿转载
