It is shown that these two sequences converge monotonically to a unique solution of the finite difference system.

Based on the theory of least square method,combined with small residual sum of squares and large residual sum of squares,applied with the method of finite difference,a new algorithm can be concluded .

Flier plate role research with difference method in characteristic line;

Based on the calculation of flowfield around the icing surface, through judging the droplet location and determining the insert value of flowfield velocity at the droplet location in a given cell and judging the boundary of the droplet trajectories, numerical results of the equations of motion for the droplets are presented by using a difference method, and the droplet trajectories are obtain.

In the paper,through heat transfer realizing process, the one kind of different extending boundary pattern in difference method is compared with another .
