abstract evolution equation的用法和样例：
- 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.
- A permeable tensor evolution equation of equivalently continuous medium has also been developed.
- In the article we show the decay of the solution for some nonlinear evolution equation of second order by using a difference inequality.
- The major contents in this paper include: the exact solutions of the non-linear evolution equation and the integrable system.
