By using geological and geochemical data, the genetic type of the Silurian asphaltic sandstones in Tarim Basin is investigated and divided as the following:(1)Oxidized asphalt on surface or in shallow-layer is the heavy asphalt crude and solid oxidized asphalt or gilsonite formed by volatilization, oxidization, water washing and biodegradation in oil-layer outcrop area or near earth surface.

通过对地质、地球化学等资料的研究，认为塔里木盆地志留系沥青砂岩有5种成因类型：①表生—浅层氧化沥青是指在油层露头区或油层位于近地表处，由于挥发、氧化、水洗和生物降解等作用而形成的一些焦油状沥青质重油以及固体浅层氧化沥青或硬质沥青。

Under polarizer,two kinds of bitumen,oily and colloidal/asphaltic,respectively,can be observed,and both of them often coexist and their amounts are complementary.

在偏光镜下，可分为油质沥青和胶质—沥青质沥青两种，两者常常共存，含量为互补关系。

This paper concludes the study methods of oil and source rock correlation for heavy oils with different degree of biodegradation;correlates the heavy oil and source rock in the western depression of Liaohe oilfield using the method of asphaltic ruthenium ion catalysis-oxidation and analysis of wrapped hydrogen in asphalt.

总结了不同生物降解程度的稠油油源对比相应的研究方法；利用沥青质钌离子催化-氧化、沥青质中包裹烃等新方法对辽河断陷西部凹陷稠油油源进行了对比研究。

The cokes are come from aromatics, colloids, asphaltene and Carbenes which are polycondensated and dehydrogenated. The processing of coking in the system are as follows: aromatics－→colloids－→asphaltene－→Carbenes－→cokes.(4) Coking can be avoided in the plasma reactor by feeding coal powder of 40～60 mesh (30%) and coal powder of less than 140 mesh (70%).

3结焦主要发生在等离子体反应较高温区，由煤中的芳香分、胶质、沥青质和碳青质缩聚脱氢形成；装置结焦形成的大体途径为：芳香分－→胶质－→沥青质－→碳青质－→焦质。

The results showed that changes of content of saturants, aromatics and asphaltenes were similar during the three kinds of aging test, i.e.

结果表明：在三种老化过程中沥青的芳香分含量均显著减少，沥青质的含量均明显增加，饱和分只有少量的挥发衰减；在短期热氧老化和长期光氧老化试验中胶质含量均降低，但在长期热氧老化中胶质含量增加。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
