1发光管或光敏元件老化：光电鼠标的核心IC内部集成有一个恒流电路，将发光管的工作电流恒定在约50mA，高档鼠标一般采用间歇采样技术，送出的电流是间歇导通的(采样频率约5KHz)，可以在同样功耗的前提下提高检测时发光管的功率，故检测灵敏度高。

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。

When male mated consecutively in a night, mating interval, duration for mating, each mounting, intromission and the last mount, and copulatory mass kept constant, suggesting that male possess a pattern of constant mating investment, which might result from intense sperm competition in this species.

雄兽连续交配时，交配间隔、交配持续时间、每次爬跨持续时间、总爬跨持续时间、最后一次爬跨持续时间、射精持续时间等行为参数以及交配栓的重量均保持不变。表明雄兽具有恒定的交配投资模式，这种模式可能起因于该物种雄性之间激烈的精子竞争。

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.
