In any fluid handling system , valves are the controlling element : starting or stopping flow , regulating or throttling flow , preventing backflow , or relieving and regulating pressure
在任何流体处理系统中，阀门是作为控制装置：启动或停止流体流动，对流体进行调节或节流，防止倒流，或释放和调节压力。
In order to improve measurement precision and display fidelity of the instrument , three new methods of nonlinear calibration of thermal instruments , which are based on intelligent control theory , are presented in this paper , such as nonlinear compensation of zr02 oxygen measurement instrument using bp nn , nonlinear calibration of temperature measurement sensors using cmac nn and nonlinear identification of throttle flow meter using ga . these methods prove to be not only simple but also effective
火电厂热工仪表普遍存在非线性特性，为了提高参数测量的准确度和仪表显示的精确度，基于智能控制理论，文中提出了热工仪表非线性校正的新方法： bp神经网络补偿氧化锆氧量计非线性特性的方法、 cmac神经网络校正测温传感器非线性特性的方法、遗传算法辩识节流式流量仪表非线性特性的方法。
