期望值

We have very high expectations, and part of that comes from our individualistic ethic in the U.S., she explains.

我们有相当高的期望值，这其中有一部分是来自美国的个人主义伦理

This research design each intersection offset by relative offset, and derive a "the expected value of progressive intersection number model". This research is for the sake of improving the traditional bandwidth method which is unable to accord with progression demand of every intersection to assign the progression ability effectively, and know the vehicles' real progression ability in the arterial system.

由於群组划分后各子系统路口时差以「绝对时差」进行设计，将无法直接进行相异周期之群组间路口时差最佳化求解，本研究遂以「相对时差」进行各路口间时差设定，并推导一「续进路口数期望值」模式，以改善传统绿灯带宽法无法依据各路口续进方向之交通需求量，有效分配各路口双向续进能力，且无法由绿灯带宽得知系统内车辆真实的续进能力之问题。

This paper introduces how to use PLC realize PID automation control system in constant liquid level system of waterworks though a instance project. It adjusts liquid level by control the valve though PID arithmetic and deals with outside program, makes the liquid level constant at the expectation value. The adjusting time is the same as manual control, but the water quality is better. Its advantages are reaction rapidness, auto-control disengage intervenor, quick protection of fault, more safety and stabili...

本文以一工程实例介绍了如何用PLC在水厂的滤池实现PID恒水位控制，它通过PID算法和外围的程序处理，通过控制阀门开度来调节水位，使水位基本恒定在期望值，并且阀门调节次数基本与手动调节一样，但水质却明显好很多，更重要的是对现场适应能力强，反应快，而且完全脱离人为干预进行全自动控制，对故障也有快速保护，更具安全稳定性。
