region of operation

However,HCCI engine could not be employed widely because of its limited operating range.

均质充量压缩燃烧(HCCI)技术由于其较高的燃油经济性和极低的NOx及PM排放越来越受到重视,但是由于HCCI模式发动机运行区域狭小,限制了其在实际中的应用。

The functional intersection area and steady movement area of highway intersection are analyzed by theories and experiments.

以分析影响公路平面交叉口间距的关键因素为切入点,用理论分析和试验观测的方法来分析交叉口功能区和平稳运行区长度,并采用交通仿真手段分析延误、交通量、信号周期、绿信比和饱和度对交叉口间距的影响;最后提出了公路无信号交叉口和信号交叉口合理的最小间距的指标。

This article puts forward transformer economical operational area concept by analyzing transformer efficiency, not only transformer can be operated economically, but also operating number of transformer can be reduced.

本文通过对变压器效率的分析,提出了变压器经济运行区的概念,不仅使变压器在不同的运行方式下实现其经济运行,同时又可以大大的减少变压器的操作次数,从而为真正实现变压器的经济运行,提供了理论依据。

Through division of constraint conditions of units into security operation zone and non-security operation zone, a new model for internal economic operation is proposed.

通过划分机组的约束限制条件为安全运行区和非安全运行区,提出了一种基于开关控制策略的厂内经济运行模型。

This paper made multi-level analysis and diagnosis to solve the problems of sudden increasing vibration of air compressor,high temperature of bearings,with water in shaft seal of five grades to identify the optimum operating area of air compressor to achieve stable,super-cycle operation of air compressor.

通过对4 500Nm3/h制氧机系统的透平空压机绘制轴承振动劣化趋势图,捕捉设备各种异常现象,经多层次分析诊断,解决了空压机振动突然增大、轴承温度过高、五级轴封带水等问题,找出了空压机最佳运行区域,实现了空压机超周期平稳运行。
