摘要
在半无界管状区域中的Stokes方程的初边值问题中,以该问题的解定义了一个加权能量函数E(z,t),通过计算,导出了以该能量函数为未知函数的二阶微分不等式,并得出该能量函数随着z与有限端距离的逐渐增大而呈指数式衰减的估计结果。
In this paper, the solutions of the Stokes equations in a semi-infinite cylindrical pipe are discussed. The authors defined it to be a weighted energy functional of E(z, t). It can be deduced a second order differential inequality and an exponential decay estimates in terms of the distance from the finite end of the pipe is obtained.
