火星和地球上山峰最高高度及其差异研究

Study on the heights of the highest mountains of Mars and the Earth and their difference

火星的半径只有地球半径的一半多一点,而火星的最高峰奥林匹斯山比地球的最高峰珠穆朗玛峰的两倍还高,火星上还有不少比珠峰还要高得多的山峰.为解释这种与天体尺度不成比例的山峰或凸起的出现原因,建立了一个山峰的应力模型,发现影响山峰高度的主要因素是重力加速度.越是小的天体,它的表面重力加速度越小,表面的凸起就越显著.同一模型亦较好地估算出与实际相近的地球最深海沟的深度.

The radius of Mars is only half of that of Earth,while the height of Mount Olympus,the highest mountain on Mars,is more than twice of that of Everest on Earth.There are still some peaks on Mars which are much higher than Everest. To explain the appearance of mountains or protrusions disproportional to the scale of the planet,a stress model of a mountain was set up.It was found that the main factor that affects the highest mountains'height is gravitational acceleration.The smaller the planet,the smaller its surface gravitational acceleration,and the more prominent the protrusions on its surface.The depth of the deepest trench on Earth was also estimated using the same method;the result is close to reality.
