北半球向南平抛物体的运动方程及其偏离表达式

The Kinematical Equation and the Expression for Drift of a South Horizontal Projectile in the Northern Hemisphere

为了更全面地研究北半球抛体运动的运动方程和偏离问题 ,同时考虑了地球自转和空气阻力对抛体的影响 ,通过解微分方程组 ,得到了北半球向南平抛物体的运动方程和南偏、东偏表达式 。

In order to comprehensively discuss the kinematical equation and the expression for drift of a projectile in the northern hemisphere, the influence of the earth ratation and the air drag force are both considered. The kinematical equation and the expression for southward drift and eastward drift of a projectile when the air drag force is direct ratio to the projectile's velocity are obtained by solutioning a set of differential equations .Some discussions about drift are given.
