本着“百家争鸣”之旨,为了活跃学术讨论,提出下面的看法就正于原作者和广大读者。 此文的要点在于把弹性波在半平面内的折射和反射情况加以改进而适用于1/4平面内。这时由于边界条件较为复杂,问题较难求解。 当半平面内弹性入射波为纵波时,取波函数为 In the “one hundred schools of thought” purposes, in order to active academic discussion, put forward the following views on the original author and the majority of readers. The main point of this paper is that the refraction and reflection of the elastic wave in the half-plane can be improved to fit in 1/4 plane. At this time, due to the more complicated boundary conditions, the problem is more difficult to solve. When the half-plane elastic incident wave is a longitudinal wave, take the wave function as
