Whereas the impact of the environment fragility on economic growth has shorter skewing, which is a kind of short-term and non-asymptotic influence.
而环境脆弱性对经济增长的影响的时滞却较短，是一种短期的、非渐进的影响。

This article makes use of variable gradient method and structure Lyapunov Function to solve a kind of global asymptotic stability for solutions of non-linear system of the second order.

The second example is the asymptotic periodic solution and the dispersion relation of weakly non-linear waves in a self-gravitating medium.
