A practical method of measuring microwave resonator unloaded Q-factor is presented, which could eliminate phase shift of feed line when Q-factor is estimated by critical-points method.
提出了一种实用的测量微波谐振器无载品质因素的方法，在临界点法的基础上，消除了馈线引入的相移。
The first observation is we cannot use our usual method of looking for critical points of f.
好，在这种情况下我们首先发现,之前用来找极值的方法都不可用。
Secondly, the method of block-match is used to track the critical feature points.
