地球自转、形状和重力加速度随纬度的变化

The rotation and shape of earth and the gravity acceleration's variety with latitude

分析地球形状、重力加速度与地球自转三者之间的关系,利用旋转椭球模型和大学物理知识计算地球重力加速度分布,计算结果与国际上公认的数据相符.

The relationships between the rotation, the gravity acceleration and the shape of the earth are analyzed. The gravity acceleration is calculated based on the model of rotating ellipsoid from physical knowledge of undergraduate course.
