哈夫曼树中,树的带权路径长度的含义是各个字符的码长与其出现的此时的乘积和, 也就是电文的代码总长,所以采用哈夫曼树构造的编码是一种能使电文代码总长最短的 不等长编码。-Huffman tree. tree with the right path length is the meaning of the various characters code length of time with the product and, is the message code chief Therefore, the tree structure used Huffman coding can be a code message from the chief of the shortest length coding.

给出了沉浸式虚拟维修仿真系统的框架，从样机建模和交互技术两个方面对其关键技术进行了研究．提出 了虚拟维修样机的概念，通过定义样机部件的约束运动和交互特征来实现其所要求功能，而交互技术则主要集中在 抓取和防穿越处理上．建立了基于Jack系统的沉浸式虚拟维修仿真原型系统，并以某机构的拆装为例对其进行了初 步的应用验证-Give the Immersive Virtual Maintenance Simulation System framework, from prototype modeling and interactive technology for its two key technology areas were studied. Put forward the concept of a virtual prototype of repair, by the definition of prototype components bound to exercise and interactive features of implementation of its functional requirements, and the interactive technology was mainly concentrated in the crawl up and deal with anti-crossing. Jack set up a system based on Immersive Virtual Maintenance Simulation prototype system and the dismantling of an institution as an example of its application for a preliminary verification
