摘要
介绍了等精度测频法的原理，并应用该原理对疲劳试验机电机转速转数进行了数字化测量及显示，通过与测周法比较，得出了这种原理的优越性。
The principle of equal precision measuring frequency wayis introduced ,then uses it in speed and revolution numerical measuring and displaying of fatigue experimental machine.Througcomparing it measure frequency way and measure cycle way, equalprecision measuring frequency ways advantge is obtained.
