In physics, the physical parameter evolution along with the time is often controlled by the non-linear partial differential equation.

在物理学中，物理参量随时间的演化往往是由非线性的偏微分方程支配的。

Increasing a speed parameter for each water node, we adopt the idea of neighboring regions spread to derivate the evolution formula of water wave with disturbance.

采用邻域传播的思想，为每个水结点增加一个速度参数，推导出水面受到扰动后，水波的演变公式。

Based on the assumption of water resources system is a dissipative structure, the water is regarded as a sequential parameter to describe the sequence and evolution direction of system.

水资源系统是一耗散结构，本文以水资源量作为序参量，来描述水资源系统的有序性和演化方向。
