摘要: 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.

关键词: 重力加速度, 地球形状, 旋转椭球模型, 地球自转, 重力势

Abstract: 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.

Key words: gravity acceleration, shape of the earth, model of rotating ellipsoid, rotation of the earth, geopotential
