The carbon number distribution of normal paraffin in alkane is C_ 20& C_ 38. Cycloparaffinic hydrocarbon in alkane is less than the detection limit of NMR, and the total ion chromatogram of cycloparaffinic hydrocarbon shows that the content of alkane in cycloparaffinic hydrocarbon is very little. 链烷烃中正构烷烃的碳数分布为C20&C38,其中环烷烃的含量低于NMR的检测限,环烷烃的总离子流色谱图显示出其中的链烷烃含量很低。
Under the normal thermal conduction, the four rates of sedimentation, temperature rise, organic maturation and hydrocarbon generation are successively effective and promotive in central anticlinal zone of Xihu sag. 在正常热传导背景下,西湖凹陷中央背斜带沉积速率、升温速率、成熟速率以及生烃速率等四者之间相辅相成,依次控制;
The seismic interpretation of normal fault is very important because its obvious control role over Tertiary or even Pre-Tertiary hydrocarbon gathering and distribution. 在中国东部油区,正断层对第三系乃至前第三系的油气成藏、油气分布的控制作用很明显,因此对正断层的地震解释显得十分重要。
In the process of petroleum producing, store transport, refine processing and using, because of the reasons of accident, not normal operation and overhaul and so on, there will have petroleum hydrocarbon spilling over and emission. 在石油生产、贮运、炼制加工及使用过程中,由于事故、不正常操作及检修等原因,都会有石油烃类的溢出和排放。
Carbon number distribution and the normal hydrocarbon to iso-hydrocarbon ratio are determined on the basis of impact factors of rubber protection wax performances, and computer simulation program is developed with Matlab software using computer programming technology. 在分析橡胶防护蜡性能影响因素的基础上,设定碳数分布和正异构链烃比例两个参数,运用计算机编程技术,采用matlab软件,得出计算机模拟程序。
The tensile stress, higher pressure coefficient in whole normal condition and higher ground temperature gradient were responsible for abundance of hydrocarbon accumulation. 表现为:现今油气的富集区基本上位于地应力场中的张应力和张扭应力分布区、整体正常压力系数分布的相对高值区和地温梯度的相对高值区。
It clearly shows that both normal oil and high-waxy oil were migrated to the the slopes from the centre of hydrocarbon kitchen of depression centers and were enriched in the reservoirs of the favorable traps. 反演结果表明,正常油和高蜡油都是围绕各自生油洼陷中心向周围构造高部位的斜坡带运移,在有利的圈闭中成藏。
In the normal course of producting hydrocarbon, hydrocarbon is colorless, transparent, volatile, inflammable, explosive, impurity is less. 在正常的产烃的过程中,烃产品为无色较透明的易挥发的易燃易爆液体,杂质较少。
