用牛顿力学基本原理分析海洋的潮汐现象

Analyzing Ocean Tide phenomenon by Basic Principle of Newton's Mechanics

本文利用牛顿力学基本原理定性和定量地初步分析了海洋的潮汐现象.海洋的潮汐现象基本来自月球的引力作用,在较小程度上也来自太阳的引力作用.潮汐产生力决定于引力的梯度,据此给出了潮汐产生力的全貌,估算了在开阔海面处潮的平均高度,讨论了太阳引力的影响及大潮小潮等问题.

the articale initially analyzes ocean tide phenomenon qualitatively and quantitatively by the principal law of Newton's mechanics.The tide phenomenon of the ocean is produced by the gravitation of the moon,at smaller extent,also by the gravitation of the sun.The tidal force decides gradient of gravitation,according to this,tide force of full view is gained. The usual height of the tide can be calculated at the broad sea surface.Still talking about the influence of the sun and high,low tide question and so on.
