The ore-forming fluid is of medium-low temperature, low salinity, and low fugacity of O2 and S2. 成礦流體為中低溫、低鹽度、弱酸性、低氧逸度和硫逸度。

A new method to calculate the volume and fugacity of saturated vapor is obtained. 本文得到了一種不用狀態(tài)方程計(jì)算飽和蒸汽摩爾體積的新方法。

When they are used to calculate fugacity coefficients of pure gases, the confident levels... 用于純氣體逸度系數(shù)計(jì)算,偏差小于5%25的置信水平在97%25以上。

Based on a brief analysis of the genesis of hematite, the authors hold that hematite in red granite was mostly produced under the condition of high oxygen fugacity. 本文對(duì)赤鐵礦的成因作了簡(jiǎn)要分析，認(rèn)為紅色花崗巖中的赤鐵礦大多為高氧逸度條件下的產(chǎn)物。

The article sums up the constitutional equation of authentic gas and recommends a convenient formula of calculating fugacity. 本文歸納了真實(shí)氣體的狀態(tài)方程

From early to late stage metallogenic hydrothermal activity evolves from high to low altitude in space, and the oxygen fugacity changes frow lowto high value. 成礦熱液活動(dòng)由早階段到晚階段在空間上似具有由高向低、氧逸度具由低到高的演變特征。
