摘要 讨论了行波在结构中的传播规律,通过对波动方程的数学分析,解释了某些重要的波动现象(惠更斯,影响城,推迟势,波阵面)。 The paper discusses the law of travelling wave propagation in homogeneons medis.Some wave phenomena (Huyghen,influence domain,delay potential,wave front)have been explained by mathematic analysis of the equations of wave motion.A closed solution for the transient wave excited by the boundary of a waveguide is gained.
