The application of sulfur isotope tracing involves the physical and chemical conditions, origin of ore-forming minerals, denudating degree of orebody, ore enriching position and genesis types of deposits. In the application, the geology of the hydrothermal deposit should be well understand to distinguish metallogenic epochs and judge the isotopic fractional equilibrium state, combined with the Ohmoto mode to study the factors possibly affecting hydrothermal fluid system.

在总结前人研究基础上，综述了硫同位素在热液成矿作用中成矿物理化学条件、成矿物质来源、矿体剥蚀程度、矿化富集部位、矿床成因类型等的示踪意义，认为硫同位素示踪应用须在了解热液矿床基础地质前提下，准确区分成矿期次，判别硫同位素分馏平衡状态，结合Ohmoto模式综合研究影响成矿热液体系的各种因素才可以赋予同位素准确的地质内涵。

The laser that compares two kinds of different wavelengh denudes system, medium holds back discharge fractional to the element of laser of 213 Nm solid effect improves function apparent.

Stable isotopes of carbon and sulphur are fractionated during cycling between surface reservoirs and geological reservoirs.

碳、硫在表层储库和地质储库以不同的形式相互转换，在这个过程中都伴随着一定的同位素分馏。

Oil must be fractionated into it's component parts to be useful and sometimes chemically converted to a more usable form, using cracking for example

石油必须先分馏成各种有用的成分，有时还通过化学反应转化成用途更大的形式，例如裂解。

The oil yield of six types of Huadian oil shales were measured on a Fischer assay retort,and the factors which effected the results of Fischer assay of oil shale were investigated,such as heating rate,particle size,final retorting temperature and retorting persistent time.

结果表明，页岩油的产率随着挥发分含量的增大而增加，在一定范围内提高升温速率，页岩油产率增大，但升温速率过快，反而使页岩油产率降低；终温在500℃~510℃，持温时间20 min的条件下，产油率最高，继续增加干馏终温和持续时间对产油率影响不大；同时适宜的粒度可以适当提高页岩油的产率。

The source of the asphalt and the crude oil are homogeneity in some way, but lanthanon fractionation of the asphalt is relatively high. So it can show that the asphalt is higher than the evolution degree of crude oil. Origin has also variety, some samples maybe exert deep fluid.

表现出两者在来源上具有某种程度上的同源性，但沥青的稀土分馏程度较石油大的多，由此表明沥青的演化过程较石油更复杂。

The pumps have been specifically designed to avoid reverse fractionation, minimize tar formation and pump back streaming.

该泵是专门设计用来防止反向分馏、减少焦油的形成和泵回流。

The Nutracor is a calcium soap of long chain fatty acids made from freshly processed fatty acid distillates of palm and reacted with calcium sources.
