地貌形态形成和发展的第三营力——陨击力

根据现代对星体碰撞理论的研究,源于陨石撞击地球表面产生的,并形成陨击坑地形形态的动能,我们称之为陨击力.陨击力作用形成的陨击坑,是太阳系众多固体行星表面上常见的,具有时空普遍性的特征,在地球表面则成为一种特殊的构造地貌形态.因此,与内营力和外营力相并列的陨击力—第三营力同样是地壳表面形态形成、演化和自然地理条件变化的重要动力.

The Third Stress Force for the Formation and Evolution of the Landform——Meteorite Impact Force

According to the study of modern colliding theory, a kind of kinetic energy coming from the collision of the meteorite with the earth and forming the meteorite crater tectonic landform is called meteoritic impact force. Meteorite craters formed by meteoritic impact force are common on the surfaces of most solid planets in the solar system, and they are of universal characterises at any time at any space. They become one kind of special tectonic landform, called meteorite impact landform. Thus meteoritic impact force being justaposed with internal stress and external stress, i. e. the third stress force, is equally an important kinetic force for the formation and evolution of the landform and for the changes of physical geographical conditions.
