time interval method meaning in Chinese

隔时法
时间间隔法
时间间隔平均法

The methods of direct measurement with low precision such as frequency and time interval methods and the methods of indirect measurement with high precision such as beat frequency method , dual mixer time difference method and frequency difference multiplying method are supported on the platform . the fundamentals of each method are studied . the quantization error is analysed and the illustration is given for each method
该平台支持直接频率和时差法两种较低精度的测量方法以及双混频时差法、差拍频率法和频差倍增法高精度的简接测量方法，本文研究了各种测量方法的原理，对各种测量方法的量化误差作了分析，并给出具体的实例。
