如何“写”出平面简谐波的波函数

HOW TO "WRITE" THE WAVE FUNCTION OF THE SIMPLE HARMONIC PLANE

介绍了大学物理课堂中讲授平面简谐波波函数的一种教学设计,其核心是在课堂教学中归纳总结出平面简谐波波函数的一般形式,为学生提供处理波函数问题的简单方法,该方法只要给定任意点的振动方程及波的传播方向,就可依据一般形式"写"出平面简谐波的波函数.

In this paper, we have introduced a kind of teaching design which is to teach the wave function of the simple harmonic plane in the college physics courses. The key is to summarize the general form of the simple harmonic plane wave function in class teaching, and provide students with the easy method to solve the wave function problem. Once the vibration equation of arbitrary point and the wave propagation direction are given, using this method, the wave function of simple harmonic plane can be written through the general form.
