The phase coincidence phenomena is a especial phase relation between two frequencies, and usually can be used in high precision instruments design.
相位重合是两个频率信号的一种特殊相位关系,利用它往往能设计出高精度的仪器。
The analysis indicates that the mismatches can lead to the possibility that the phase of phase coincidence TWT can be compensated. It is necessary to measure the…
