| 摘 要： | 对含有梯度项的退化抛物型方程(组)初边值问题的研究,己知的结果似乎较少.本文采用抛物型正则化的方法,讨论了一类带有梯度项的退化抛物型方程组的初边值问题,得到了其非负连续解的整体存在性,推广了 Maddalena L 的结果.

| Abstract: | It seems that we haven't got much information about the initial-boundary value problem of the degenerate parabolic equations containing the gradient terms.In this paper,with the method of parabolic regularization,the author proves the global existence of nonnegative solution for the initial-boundary value problem of a class of degenerate
parabocic equations containing the gradient terms.It extends Maddalena L's result. |

| Keywords: | degenerate equation nonlinear parabocic eguations weak solution boundary value problem |
