摘要
通常，利用调制反射法测量高能电子直线加速器波导网络的相长度。文章介绍利用３ｄＢ桥特性测量波导系统相对相长度的方法。该方法简便易行，精度较高，满足相对测量的要求，其误差好于±４°。
Modulated reflection method is used in general for measuring phase lengths of waveguide net-work in construction of electron linear accelerators. Another method of utilizing characteristics of3 dB coupler to measure relative phase lengths of waveguide branches of electron linear acceleratoris introduced.The metbod is feasible to use and is rather accurate. Error of measurement is esti-mated as less than ± 4°.
