The a priori estimate is established to the maximum modulus of solutionsof doubly nonlinear parabolic systems. 对一类双非线性抛物组的有界解，作出最大模的先验估计。
Maximum modulus principle plays an important role in the complex analytics, and it is a powerful tool in studying the analytic function. 摘要最大模原理在复变函数论中占有重要的地位，是研究解析函数的有力工具。
