Based on chinese traditional philosophical thinking , beginning from introducing the chinese traditional ecological main ideas , this paper analyzes the meanings of ecological culture in the chinese traditional building unit from its three parts - roof , body and platform , and approaches the relation between these meanings and the chinese traditional ecological main ideas , in order to deeply understand the design theory and method of chinese traditional architecture from different angles and provide a salutary reference for modern arcology study 摘要该文以中国传统哲学为背景，在简要梳理中国传统生态核心思想的基础上，以中国传统建筑单体作为研究对象，分别从建筑单体屋顶、台基、屋身三段构成来分析其生态文化内涵，并探讨它与中国传统生态思想之间的相关性，以求从一个新的角度来认识中国传统建筑的设计理论和方法，也可为现代生态建筑的发展提供借鉴。
Just based on the two points mentioned above , a control system of doubly - fed variable speed constant frequency ( vscf ) wind power generator based on 8xc196mc is designed in this paper , which can smoothly transform between the different operational modes from sub - synchronous speed to synchronous speed and to super - synchronous speed 正是基于上述两个出发点，本文设计了一台基于8xc196mc单片机的2 . 8kw变速恒频双馈风能发电控制系统。主电路中变流器的设计可使该系统能工作于亚同步速、同步速及超同步速三种运行状态，并具有能量双向流动的特点。
The designed base - station and substation ( dolly controler ) both have infrared interface which can beam and receive infrared signal . by accreting the beaming power , one base - station can control 64 set of substations at mostthe base - station and master pc computer is connected with rs - 485 interface , this fullfils the demand of long - distance and high - speed commnication 通过增大发射功率，一台基站最多可控制64台从站。基站与上位pc机之间采用rs - 485接口进行通信，可以满足远距离高速通信的要求。
After that , based on the pcnc system adopted software nc dos application , the detailed design and development process of dnc system is put to study . under this background , the whole system architecture and related techniques are mainly discussed . finally , this paper takes a practical dnc project as an example to describe how to design and develope it under the above circumstances 再次，介绍了pcnc系统的发展现状、软硬件结构，同时结合pcnc和dnc各自的特点及发展趋势研究了pcnc环境下dnc的组建方案，并针对多台基于dos数控软件的pcnc系统这一具体环境，详细叙述了其dnc系统的总体设计方案、软件开发及其关键技术等。
