摘要
本文推广了对称开拓法,解决了阻尼波动方程在有限端具有某一类边值条件的半无界问题,并求出解的表示式,该方法也适用于热传导方程的半无界问题。
The author applies the symmetric prolongation method to the semi-unbounded problem of the daming wave equation with some boundary condition at the finite end and gives the representation formula of the solution to it.The method used in the paper is suitable for the semi-unbounded problem of the heat condition equation.
