1·The second presents the marching iteration method with pressure relaxation factor.

第二部分介绍带压力松弛因子的推进迭代方法；

2·During the solution iterations, the residual change is used as accelerating factor to revise weight function. As a result, the number of iteration and the calculation time are decreased.

在求解迭代过程中，以残差变化量作为加速因子，修正权函数，减少了迭代次数，加快了算法的计算速度。

3·Guaranteed by the indentation factor, the improved PSO algorithm can keep the iteration particles in feasible region.

通过引入缩进因子，改进P SO算法，使粒子在迭代过程中保持在可行域内。

4·A revised fuzzy control algorithm was developed to accelerate iteration convergence in numerical fluid dynamic simulation by adjusting the value of the under-relaxation factor.

在原来研究工作的基础上，提出了一种改进的模糊控制方法，用以调整粘性流场迭代计算中亚松驰因子的值。
