然后为了能有效求解所得模型，本文利用有限差分方法构造了一种半隐式的数值离散格式，同时给出了模型中的几个重要参数的估计。

Furthermore, in order to solve the proposed model efficiently, we construct a semi-implicit numerical scheme by using finite difference method and estimate some important parameters.

同时该方法通过引入粒子数密度的概念和半隐式算法，有效地保持了流体的不可压缩性。

And at the same time introduce the concept of particle number density and the semi-implicit algorithm, effectively maintain the incompressible of the fluids.
