摘　　要：文章用输入阻抗方法探讨同轴探针中心对称激励矩形波导在多模传输时所能激发的传输模式。说明采取一定的措施,可以避免产生某些高次模式。并应用分式线性变换检测法,以精心设计的实验验证了理论分析的正确性。Using input impedance method to discuss which transmitting modes can be exited in a rectangular waveguide driven by a coaxial-line probe on center in multi-mode transmission, the paper shows that some certain high-mode waves can be avoided by taking some measures. And using the linear fraction transformation detecting method, an exact experiment is designed and done to prove the validity of the theory.
