南半球竖直上抛落地偏差之研究

Research into the falling deviation of vertical projectile in the southern hemisphere

地球既有自转又有公转,所以是非惯性参考系.在自转过程中可以认为它的角速度是沿着地轴的一个恒矢量.因而只需考虑惯性离心力和科里奥利力所产生的影响.本文就是通过科里奥利力效应研究南半球竖直上抛物体的落地偏差问题,并给出一种解法及其精确解.

The earth rotates and moves around the sun,so it is a noninertial reference frame.In rotation,its angular speed is a constant complexor along the earth's axis,and hence the effects of inertial centrifugal force and Coriolis force are considered.This paper,in the light of Coriolis effect,studies the falling deviation of vertical projectile and gives a solving process and an exact solution.
