【摘要】 利用定义广义奇(偶)函数及其性质,给出了在各种边界条件下,定义在有限区间上的具有奇(偶)外部激励条件的波动方程的混合问题解的有限形式,并指出了在此条件下,与定义在无限区间上的初值问题一样具有行波解.更多还原

【Abstract】 By defining generalized odd(even) function and its properties,the finite form solution of wave equation mixed problem which is on various boundary conditions is given.The wave function defined on the finite interval owns odd(even) exterior encouraging condition and also shows that the initial value problem has progressive wave solution on such a condition.更多还原
