一根长直绷紧的弦,对一点给一轻微扰动,这一点的扰动必定扰动其左右邻段。邻段的扰动再分别影响它们的邻段,这样振动就像两端传播开去。这一现象我们称为波。
通过数学手段将波动问题转化为数学问题加以理论研究,即将物理问题转化为数学问题,这一过程中需要将物理现象所发生时的环境因素考虑进去,我们称环境对物理现象的影响为边界条件。一般的数学物理方程通常有无数组解,往往根据边界条件要求的不同而求出需要的特解。
波动方程是最基本的二阶双曲型方程,对求解非齐次波动方程可采用分离变数法和傅立叶级数法直接求解,也可以采用冲量定理法将方程转化为齐次方程,求解后利用叠加原理将所求的解叠加。
翻译成英语,辛苦你啦。

Tension of a long straight string, the point to a slight disturbance, the disturbance that must be about the disturbance of their neighbors paragraph. Adjacent section of the impact of disturbance respectively above their neighbors, so that both ends of the vibration as spread from person to person. This phenomenon we call a wave.
Through mathematical means fluctuation issues into theoretical study of mathematics, physics is about to issue into a mathematical problem, this process needs to be at the time of the physical phenomena of environmental factors taken into account, we call the environment on the physical phenomena of boundary conditions for . Equations of mathematical physics in general whether there is usually an array of solutions, often in accordance with the requirements of the different boundary conditions needed to derive the special solution.
Wave equation is the most basic second-order hyperbolic equations, to solve the non-homogeneous wave equation using
