【摘要】 由龟山岛热液气体推断几个可能化学反应方程式的存在,根据相关的假设条件,尽量接近于真实的龟山岛热液环境情况,通过计算、比较这些可能存在的化学反应在标况和龟山岛热液条件下的平衡常数,得出龟山岛热液活动区自然硫的形成可能反应式2H2S(g)+O2(g)=2S(s)+2H2O(l)和CH4(g)+SO2(g)=3S(s)+2H2O(l)+CO2(g)起到了较大的作用。这与龟山岛热液活动所具有的水深浅,周围氧气含量高的事实以及采集的热液气体中含有大量CO2气体等情况十分一致。更多还原

【Abstract】 It was suggested that several chemical equations should exist according to hydrothermal gas of Kueishantao.Setting a hypothesis on which the real Kueishantao hydrothermal environment is approached most likely,the equilibrium constant of probably relative chemical equations can be calculated and compared.It was drawn that based on two chemical equations,2H₂S（g）+O₂（g）= 2S（s）+2H₂O（l） and CH₄（g）+SO₂（g）=（3S（s）+2H₂O（l））+CO₂（g）,it is certain that native sulfur can be formed in Kueishantao hydrothermal area.At the same time,the fact is consistent with the high oxygen content because of shallow depth and high carbon dioxide content collected from hydrothermal gas.更多还原
