在数学建模中关于炮弹弹道问题相关的一些程序-Some of the procedures in the mathematical modeling ballistic

使用数值积分法进行弹道预报，弹道建模时考虑进J2摄动项的影响，并包含短周期项(The numerical integration method is used to predict the trajectory, and the influence of the J2 perturbation term is considered when the trajectory is modeled, and the short term term is included.)
