First, by virtue of semigroup theory, the considered system is converted into an evolution equation in abstract space and the uniqueness of the solution to the evolution equation is proved. 首先将所讨论的系统化为抽象空间中的发展方程
A permeable tensor evolution equation of equivalently continuous medium has also been developed. 基于岩体裂隙的损伤变形，提出了裂隙岩体渗透张量演化方程。
abstract delay evolution equation 抽象时滞发展方程
In the article we show the decay of the solution for some nonlinear evolution equation of second order by using a difference inequality. 本文应用一个差分不等式证明了一类二阶非线性发展方程初边值问题整体解的衰减性质.
The major contents in this paper include: the exact solutions of the non-linear evolution equation and the integrable system. 本文研究的内容主要包括两个方面：非线性发展方程的精确解与可积系统。
