编制了计算程序，精确地算出了微波腔体的谐振频率和无载品质因数。
The resonant frequency and unload quality factor are calculated accurately and the program with FORTRAN language is worked out.
最后对无源交调，无载品质因数测量，多工器调试这几个工程中实际问题进行了剖析。
Finally, this article gives the methods to control passive intermodulation, measure unloaded Q and to tune multiplexer.
