摘要
考虑一类含有双调和算子的热弹性板的空间性质,通过构造一个能量函数,利用微分不等式技术,推导出该能量函数可由其自身一阶导数控制的微分不等式,并给出解的Phragmen-Lindelof二择一结果.
We considered the spatial properties of a class of thermoelastic plates with biharmonic operators.By constructing an energy function and using the technique of differential inequality,we derived a differential inequality in which the energy function could be controlled by its first derivative,and gave the Phragmen-Lindelof alternative result of the solution.
