methane hydrocarbon 中文意思是什麼
-
Three kinds of microbe, i. e. methane - oxidizing bacteria, anaerobic cellulose - decomposing bacteria and sulfate - reducing bacteria, were selected for experimental study, so the disturbance of surface biochemical effect was effectively inhibited, thus causing the microbiological anomaly to be able to reflect objectively the deep - seated hydrocarbon micro - leakage, it is pointed out that the result of predicting subsurface hydrocarbon distribution by use of the microbiological anomalies is obvious
選擇三種微生物指標：甲烷氧化菌、厭氧纖維素分解菌和硫酸鹽還原菌進行試驗研究，有效地抑制了地表生物化學作用的干擾，使微生物異常能夠較客觀反映地下深部油氣微滲漏情況，微生物異常預測地下油氣的分佈，效果顯著。 -

Composition of natural gas is different in baimiao and qiaokou, though they are both wet gas. in qiaokou area, the content of methane ch4 % < 80 %, the value of the ratio between methane ch4 and heavy hydrocarbon is about 5, while in baimiao area, the value of methane ch4 > 88 %, the value of the ratio between methane ch4 and heavy hydrocarbon is more than 10
取得了如下主要認識：白廟與橋口地區天然氣雖同屬濕氣，但成分有一定差異，橋口地區天然氣甲烷含量均小於80 ，甲烷重烴為5左右；而白廟地區天然氣甲烷含量相近，普遍高於88 ，甲烷重烴10 。 -
The convective term is solved by ausm + ( a sequel to ausm which means " the advection upstream splitting method " ). the 7 species 8 steps model and 7 species 7 steps model of hydrogen / air is used in the hydrogen reacting flowfield, the 9 species 5 steps model of methane, the 10 species 10 steps model of ethane and the 10 species 13 steps model of kerosene are used in the hydrocarbon reacting flowfield, the results of the distributions of velocity, mach number, pressure, static temperature, total temperature, species mass fraction and the combustion efficiency are gained, and the numerical results of the pressure of hydrogen and methane are compared with those of the experiment
計算中通量項採用ausm +通量分裂格式，氫反應流場採用氫/空氣的七組元八方程模型和七組元七方程模型，碳氫反應流場採用甲烷的九組元五方程模型、乙烯的十組元十方程模型和煤油的十組元十三方程模型，得出了超燃發動機燃燒室流場的速度、馬赫數、壓力、靜溫、總溫和組元質量分數分佈及燃燒效率等性能參數，其中氫和甲烷的計算壓力分佈與實驗結果進行了比較。 -
In this paper, by explored geo - physico - chemical prospecting method for looking for oil in prior prospect, the authors summarize a suit of prospective technique and program, which is valid to oil - geology trait of zhidan area and composed of ; oil gas geo - chemical prospect ( acid degradation of hydrocarbon, absorbed - fluorescent spectrum, ultraviolet radiation spectrum, methane carbon - isotope ) non seismic detection in favorable explorative area which confirmed by chemical prospect ( matural potential, gamma energy spectrum. accurately magnetic analysis ) resistively prospecting in anomalous area which confirmed by physicalprospect successful general evaluation of geo - physicochemical prospect
