摘　　要：本文提出利用驻波相位测定传播常数的方法．其特点是通过测定相位检测器（如探针）后面传输线的总衰耗Ｌ与其位移ｄ的线性函数的斜率，来确定衰减常数．这为测定衰减常数特别是小衰减常数开辟了新途径．文中给出的实验结果，证实了此方法的正确性．A new method for determining the propagation constant from the phase information of standing waves is reported. The distinctive feature of this method is that the attenuation constant is the slope of a linear function of the displacement of a probe,providing a new approach for determining small attenuation constant on a transmission line. Experimental results are also given.
