一类非线性拟抛物方程解的Blow－up

On Blowup of the Solutions for a Class of PseudoParabolic Equations

用Ｆｏｕｒｉｅｒ变换方法，讨论一类非线性拟抛物方程第二类边初值问题解的ｂｌｏｗｕｐ问题。

The blowup of the solutions to the initialboundary value problems for a class of nonlinear pseudoparabolic equations is discussed by using the Fourier transform method.And the conditions of blowup of the solutions in finite time are given.
