synchronous frequency meaning in English

同步频率

The couplers of accelerator structures are important components of electron knear . the efficient delivery of power from rf sources to accelerator structures depends crucially on the coupler cavity . the input coupler cavity is to be well matched , that is to say , it must have proper coupiing . and it must be tuned to the synchronous frequency . in this way , we can obtain the maximum power . in the past , the decision of the coupler cavity dimensions is very difficult
加速结构的输入耦合腔是电子直线加速器的重要组成部分。功率从功率源输送到加速管中，就依赖于输入耦合腔。输入耦合腔在整个结构中必须有良好的匹配即有恰当的耦合度，还必须工作在谐振频率。
