摘　　要：我们利用互成倍数的频率信号周期间的相对关系,通过大量的实验证明了针对射频到微波,甚至更高的频率之间,存在大频率差异的情况下,完全可以采用时间处理的方法,基于相对低的频率信号实现比其大105以上的较高频率的频率测量。这种利用时间关系直接比对测频的方法即容易实施,且又有较高的测量精度,是实现超高频率准确测量的一种重要的新方法。By a relative relationship of two frequency signal periods with mutual integral times, and on the basis of an accurate frequency difference between radio frequency & microwave frequency and even much higher frequency with a number of experiments, a 105 ratios higher frequency signal based on time process and relative slow frequency signal will be completed.The method is easy in practice and high - precision in measurement. It is also a newly important frequency comparison approach to the accurate measurement in ultrahigh frequency.
