摘　　要：详细论述了W indows系统各种定时器的特点及其应用.利用VC++编制的测试程序、数据采集卡、和波形发生器对高精度定时器的精确度进行了测试.最后通过其在微力矩测试仪中对微电机转速测试以及在电铸仪中的应用等实例证明了其完全可以应用在某些高精度定时要求的控制软件中.Characteristics and applications of some timers that Windows offered are introduced in the article. Precision of a highly precise timer is also tested with a VC ＋ ＋ testing program, data acquisition card and a waveform generator. Through the example of its application in the rotating speed test of microtorque testing equipment and electroforming equipment, it is verified that the precision timer can be used in some occasions when high precision is requested.
