In this paper, the rezoning technique for Lagrangian meshes is discussed with equidistant principle. A Rezoning threshold value η and fourstep rezoning methed are applied. According to volume ratio, the concerned parameters of meshes between new and old one are redistributed conservatively. The numerical tests show that in order to improve the effect of rezone, not only the position of inner mesh points but also the position of bourdary points are needed to be readjusted.

The critical and oscillating appearances ane the break of the integral limit which are encountered in the numeral calculation of the cross section are described and treated overally. The cross sections, collision integrals, and transport coefficients of noble-gases are calculated, according to the interactions of noblegas atoms by our method. The transport coefficients are compared with the experimental

In this paper, basic thought on simulating slide motion of Wilkins have been applied to Solve problem of two intersecting Slide lines. The programing for inferaction between flying plate and target have been made and fwo numerical examples have been given.

In this paper, from basic thought of Wilkins method, the computational method of J-(radial) slide line have been discussed in two dimensonal fluid-elastic-plastic flow with axial symmetry.The programing for interaction between flying plate and target have been made and two examples of numerical sumilation have been given.
