甲烷

The literature values of methane solubility in hexane at temperatures of 298.15 K, 303.15 K and pressures up to 12.0 MPa validated the precision and stability of the apparatus. The total deviation of the system was less than 2.5﹪. The method of fitting gas solubility at high pressure by Krichevsky-Kasarnovsky K-K equation was also proposed and corrected.

利用此装置测定了温度为298.15 K、303.15 K和压力2.0～12.0 MPa下甲烷在正己烷中的溶解度数据并与文献值相比较，从实验数据的精度和重复性考察了实验装置的可靠性，实验值和文献值的相对误差均小于2.5﹪，同时根据Krichevsky-KasarnovskyK-K方程提出了一种从高压实验数据回归常压实验数据的方法。

The carbon isotope data of carbon dioxide, 3He to 4He rado and the inverted sequence of methane-ethane-propane isotope proved that the gas reservoirs in this area were resulted from the inorganic mantle source gas.
