Using the directional derivative formula, the governing equation is discreted in the physical domain in which a nonorthogonal grid system is used. Two kinds of AF2 schemes, i. e. AF2-plane relaxation and full implicit AF2, for the TSD equation are proposed. Numerical results show that the full implicit AF2 scheme converges faster than AF2plane relaxation scheme. For the rectangular wing and swept wing, the results of the present method are compared with FP results, and the agreement is good.

During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.

Because of such insufficiency, the awareness of problematic possessed by the nine people who went to North Korea, by me in Palestine, and by our comrades in Japan, all differ from one another, and from such disjuncture, we can only deduce the necessity of more internal violence and inter-faction politics and struggles, but the revolutionary subject, which tries to rise to the level of World Revolutionary War, has to be created through World War factions and world revolutionaries simultaneously sharing all military matters as the act of collective actions and collective military front.

由于这些不足，有问题的9人谁去朝鲜我，在巴勒斯坦拥有的认识，以及在日本的同志，都彼此不同，从这种脱节，我们只能得出的必要性更多的内部暴力和跨派系的政治和斗争，但革命的议题，试图引起世界革命战争的水平，必须通过二战各派分享，同时作为集体行动的行为的所有军事事务革命创造的世界和集体军事战线。
