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.

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。

Tze Wei of sulphur dioxide, hydrogen chloride, chlorine, hydrogen fluoride and other toxic gases resist sexual stronger.

紫薇对二氧化硫、氯化氢、氯气、氟化氢等有毒气体抗御性较强。
