选用欧姆龙CX-Programmer为系统软件开发平台和CPM2A整体式可编程控制器!简称PLC),并结合强电与弱点知识,设计了适合在商业办公楼、行政大楼、中小型宾馆和居民公寓等中低层建筑中使用的一种新型电梯控制器.巧妙地利用PLC自上而下的循环扫描方式，以及I/O刷新结果在下一个扫描周期保持不变等自身特点,解决了电梯运行时,顺向优先执行,呼梯信号具有记忆功能等设计难题.

The process of selecting and designing the major components for a hybrid solar collector/CHP system is described. Particular attention was given to the design of the solar collector and a number of options, including thin membrane heat pipe solar collectors (both ‘normal’ and ‘artery’ types) and hybrid heat pipe solar collectors (both wicked and wickless types), were considered. Performance comparisons were made using theoretical and experimental data and a hybrid solar collector was selected as the best option for the system. Micro impulse-reaction turbine using n-pentane as its working fluid was selected for the system although further work is being carried out on a compressed-gas driven turbo alternator. A prototype hybrid solar collector/CHP system has been constructed and the results of its theoretical and experimental testing are presented in Part II of this paper.

加药自动化是当前提高水厂管理水平,确保供水水质, 降低水厂制水成本最为现实而有效的措施。十几年来, 我国各地水厂探索试用了各种自动加药方法, 也引起了不少国外自动控制加药系统。如数学模型、模型滤池、流动电流测定等技术。
