The books shape isomerization method was studied to break some solidified design pattern in industry and the stereotyped type design idea 文章对书籍形态异化的方法进行了深入的研究,主要是为了打破目前业内一些固化了的设计模式和八股式静止的设计理论观念,起到一定的积极作用。
The relative stability of all stable geometric structures has been analyzed . the state - state correlation and the isomerization mechanism are predicted by searching the transition states 分析了各稳定构型的相对稳定性及成键特征,建立了态态相关并给出异构化过渡态,分析了各构型之间转化的途径。
Oil type 1 , non - biodegraded oil , is characterized by low viscosity , low density , high content of saturated fraction , low content of resin and asphaltene and high ratio of isomerization of steranes 第一类原油粘度和密度低,族组成以饱和烃组分为主,非烃和沥青组分含量低,甾烷异构化指标高,未遭受生物降解。
The catalytic isomerization of isoborneol in the presence or zn - laden or cu - laden catalysts , in liquid - phase or gas - phase , is reported . the effect of reaction conditions on the product distribution has been discussed 研究异龙脑在常压下被含锌或含铜催化剂催化的液相和气相异构化反应,讨论了反应条件对产物分布的影响。
The oil of type 5 is the biodegraded one from the oil of type 3 , and characterized by a density and viscosity similar to type 4 . however , the isomerization ratio is lower in the type 5 than that in the type 4 第五类原油是由第三类原油生物降解的产物,原油密度和粘度与第四类原油相近,但甾烷异构化指标相对较低。
In addition , petroleum wax production as a percentage of amount of crude oil processed has declined significantly as a number of lube producers now convert the wax in lube fractions to lubricants by isomerization 另外,石油蜡生产量占所加工的原油的百分比,已经大大降低,因为现在很多润滑生产商都在把润滑油中的蜡异构成润滑剂。

百科解释
In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms are rearranged e.g.
