The principle of constant power drive is: PD converts the change of output light power of laser diode into the change of diode current, and the change of current is feed back to voltage-current converser which adjusts output current of driver to compensate the laser diode.

这样，当激光器的输出光功率衰减时，驱动器相应的增大输出电流；当激光器的输出光功率增强时，驱动器就相应减小输出电流。对许多激光器应用来说，最希望脉冲输出，因为脉冲输出只有极小的结发热。

This paper is that dynamically demonstrates the six algorithms implementation auxiliary teaching software of the data structure It may adapt the different demand that the reader demands the algorithm data-in and the process execution control mode. During the demonstration of the algorithm implementation on the computer screen, it can appear the change status of the data logical organization or the memory structure change condition or the stack change condition in the recursion algorithm implementation.

In the aspect of Opto—electrical signal processing, because the heterodyne interference signal is a high frequency fringe signal, how to measure the phases change of this signal——including the integer part of phases change over 2π and decimal part of phases change within 2π, is a difficult problem in electrical circuit technique.

一方面，该电路能同时测量出相位改变量的2π整数部分和2π以内的小数部分，从而实现了大量程和高精度的统一；另一方面，由于该电路是模拟电路，其最高工作频率可以远大于由数字集成电路组成的条纹计数电路，故在实际应用中，其工作频率的设计范围能够适应较宽的外差干涉差频范围，这就为高速激光外差干涉测量打下了基础。

In order to analyze the influence of the center air pipe diameter change on the combustion effect, numerical modeling was applied to numerical calculation on the temperature field of such type of boiler,through which temperature field in five different schemes were obtained. In addition, the influence law of change of the diameter of the center air pipe on the temperature field was analyzed. The temperature of the nearly-back wall region takes on a firstly decreasing and then increasing change with the diametrical decrease of the central wind pipe.

为研究改变中心风管直径后的4层燃烧器对炉膛燃烧的影响，采用数值模拟的方法对该型锅炉炉内的温度场进行数值计算，得到5种不同方案下该型锅炉炉内的温度场分布，并分析了中心风管直径的改变对炉内温度场的影响规律，即后墙近壁区温度随着中心风管直径的减小呈现先降低后升高的趋势。

During the period of design, according to change direction various parameter of the arm spare parts, analyze it is anticipate by the metals to change in to take shape the Forging piece to transform process, draw up more reasonable craft process;From change direction the arm Forging piece system process, design more economic, use convenience, more reasonable molding tool.

Among the 65 types of disyllable groups ("IVB + IVA" are divided into two kinds, and are counted as two here), there are 41 types that only change the initial syllable and not the final one, 8 types that only change the final syllable and not the initial one, and 16 types that change both syllables.

在65种两字组（"阳入＋阴平"变调时分两类，这里按两种计）中，有41种只变前字不变后字，有8种只变后字不变前字，有16种前后字都变。

Some closer too much stationmaster asks time me greatly, it choose what CMS is better to choose what CMS, I do not reply one by one, communicate with everybody casually here, numerous stationmaster turns dizzily because of this problem namely, use this today, will change that again tomorrow, change change, of harm is wasteful time only, also have good one side nevertheless, learn experience namely big.

近些时间太多站长都大问我，选什么CMS较好，我不一一回复，在这里随便和大家交流一下，众多站长就是因为这个问题转得头昏眼花，今天用这个，明天又换那，换来换去，伤害的只是浪费时间，不过也有好的一面，就是学会经验丰盛。

The result makes clear, force of the grinding when using emery wheel of cast-iron bond diamond to undertake ELID grinding asks at any time scarcely change and change, and the change that adopts the grinding force when common grinding means undertakes grinding to let time increases ceaselessly, online electroanalysis the grinding function that nap makes emery wheel keeps good from beginning to end in grinding process, be helpful for saving time of emery wheel nap, improve treatment efficiency.

结果表明，采用铸铁结合剂金刚石砂轮进行ELID磨削时磨削力几乎不随时问的变化而变化，而采用普通磨削方式进行磨削时的磨削力随时间的变化不断增大，在线电解修整使砂轮在磨削过程中始终保持良好的磨削性能，有利于节省砂轮修整时间，提高加工效率。

Furthermore, while 'Englishness' is not hostile to change, it is deeply suspicious of change for change's sake, rejecting the idea that we are now committed to some inevitable mechanical progress.
