2维弹道沉积，自己设计的方案让点落下并沉积在下方，落在何处用随机抽样-two-dimensional ballistic deposition, a program designed to let the fallen and deposited on the bottom, where they fell by random

底排弹内弹道计算程序,使用VB编制，带有计算结果及附图可供参考-Interior Ballistic Caculate

用matlab进行ccrp的弹道汇编并绘制相关的参数变化图像。(The MATLAB is used to compile the ballistic assembly of the CCRP and to draw the related parameter change images.)

在一定条件下根据经典内弹道假设，进行内弹道仿真模拟，得出相应的数值结论。(Under certain conditions, the internal ballistic simulation is simulated on the basis of the classical interior ballistic hypothesis, and the corresponding numerical results are obtained.)
