| 摘 要： | 利用地质学、天文学、地球物理学、古生物学资料进行约束，对地球的去气作用进行研究发现：太阳系的部分冷物质，通过吸积作用形成早期地球.在碰撞动能转变的热能作用下，造成了早期地球的表面熔融.在熔融状态的高温高压作用下，构成地球表面物质的结晶水排出地表进入原始大气；在高温高压下分解的碳酸盐、硫酸盐、卤化物等产生的二氧化碳、硫化氢、二氧化硫、氯化氢、氟化氢等气体进入原始大气，和水蒸汽一道共同组成原始大气.当地球内部在重力势能和放射能的作用下继续熔融时，地球表面固化为原始岩石圈.后来，地球除表面岩石圈外，整个地球完全熔融.地球内部物质熔融形成的水和二氧化碳等气体，被岩石圈圈闭.只有当冰川形成和消融，引起造海和造陆作用，导致火山喷发和地震时，这些气体才可能排出地表.这些气体的排出，受地球内部的熔融状态、冰川形成的位置（是在海洋或是在陆地）、生物的演化、太阳光的强度等因素的综合影响.

| Abstract: | Based on the constraints of the data of geology,geophysics,geochemistry,astrophysics,palaeoecology,we made research on degassing of the earth.The result shows: via the accretion,portion of cold matter of solar system formed the early earth.With the effect of that collision kinetic energy converted into heat energy,the surface of the early earth melted.On the condition of high temperature and high pressure,crystal water of the substance that composing the surface earth was released into the original atmosphere,and the carbonate,vitriol and halide decomposed,the carbon dioxide,sulfureted hydrogen,sulfur dioxide,hydrogen chloride,hydrogen fluoride were released into the atmosphere,too.All these gases composed the original atmosphere.With effect of geopotential and radiation energy,when the interior of the earth continued to melt,the surface of the earth solidified to form the original lithosphere.Afterward,except the surface original lithosphere,all the earth melted completely.The gases,such as the vapor and carbon dioxide that resulted from the melting of the interior substance of the earth,were enclosed by the lithosphere.Only when the glacier formation and melting,the epeirogenesis and the thalassogenesis occurred,then the volcano and earthquake occurred,these gases could be released out of the surface of the earth.These degassing is influenced by many factor,such as the melting condition of the interior of the earth,the position of the glacier formation(in ocean or in land),biotic evolvement,the intensity of the sunshine. |
