This paper describes the asymptotic and oscillatory properties of solutions of initial boundary value problems of linear and semilinear parabolic equations of second and fourth order.
本文考虑一类二阶及四阶线性和半线性抛物方程初边值问题的解的渐近性与振荡性。
At last an initial-boundary value problem was considered and the numerical experiment demonstrated that the linear sinusoidal wave would successively evolve non-linearly into conoidal wave.
最后我们研究了初始边界值问题。 通过数值试验证明，线性正弦波会逐步变为非线性的圆锥型波。
Finally, the boundary condition and initial value are used to solve the linear equations so as to obtain the corresponding results.
最后，利用边界条件和初值条件求解线性方程组，得出相应结果。
