速度极限

With the theoretical model of spherical grain dynamics of sparse two-phase flow in single dimension, computing formulas of velocity′s attenuation and scattering distance were built for explosive residue grains in horizontal. Then, a simplified theoretical model on distribution of explosive residue was put forward on the basis of a spherical space with radius equalling to maximum horizontal scattering distance of explosive residue grains with certain diameter.
