沥青质

A mineral consisting of uranium oxide and trace amounts of radium and thorium and polonium and lead and helium; uraninite in massive form is called ''.

一种含有氧化铀和少量镭、钍、钋、铅、氦的矿物；块状的晶质铀矿称为沥青铀矿，是主要的铀矿石。

The sharp difference suggests that they have different origins: the former comes from allochthonous sapropel-type organisms of the lower strata and is the remains of crude oil, and the latter is autochthonous humic-type organic matter of sedimentary rocks between the basalt layers.

玄武岩中铜矿石沥青的δ13CV-PDB为-27.3‰～-33.2‰，平均-31.97‰，沉积岩中铜矿石碳质的δ13Cv-PDB为-20.2‰～-23.2‰，平均-22.11‰，表明二者无明显成因联系，前者属腐泥型，为石油的遗迹，来自下部地层；后者为腐植型，来自原地沉积的陆生高等植物。

Bitumen is similar to the cement and autogenic clay filled in reservoir pores, and it dramatically reduces reservoir porosity and permeability, increases reservoir heterogeneity and even changes the oil/gas accumulation history at a later stage.

沥青类似于充填在储集层孔隙中的胶结物及自生黏土，使储集层孔隙度和渗透率急剧降低，非均质性增强，甚至可改变后期油气的富集规律。

Hydrocracking tests of Canadian oil sand bitumen, Saudi Arabian heavy vacuum residue and model compound 1 -pheny1 dodecane were carried out in a batch autoclave reactor. The reaction conditions were as follows: pressure 5.0 MPa, temperature 410-430℃, reaction time 0-60 min.

采用间歇式高压釜反应器研究了加拿大油砂沥青和沙特重质减压渣油及其模型化合物十二烷基苯的加氢裂化反应，实验条件为5.0MPa、410—430℃、0-60min。

The mineralogical and geochemical research on grey-brown laminatedmud stone, oil shale of Shahejie Formation Member 1 of Gulan Subsag found that the content of sapropel was all over 97% and the content of organic matter and chloroform bituments "A" was over 1% and 0.1% respectively in 35 samples. The organic matter belonged to type I and reached the standard of good source rocks.

对孤南洼陷沙一段灰褐色纹层泥岩和油页岩、深灰色油泥岩、深灰色泥岩、灰质泥岩样品进行岩矿及地球化学分析，35块样品的腐泥组含量全部大于97％，表明生烃母质主要为藻类，为Ⅰ型有机质，所有样品的有机碳含量都＞1，氯仿沥青&A&含量＞0.1，全部达到&好烃源岩&标准，是该地区的一套优质烃源岩。

There is recent progress in theory of modified asphalts.

本文在研究沥青改质的理论问题上取得了进展。

The bitumen occurs as reticulates, impregnation, intercrystalline pores, dissolved caverns and fissures. The reservoir lithologies are shallow facies crystalline dolomites, dolomitic limestone, and paleokarst dolomite breccia.

沥青产状多以网状、浸染状、晶间孔型、溶洞型、裂缝型赋存；储层岩性为浅滩相的结晶白云岩、白云质灰岩与古岩溶角砾状白云岩。

The main products include: asphalt varnish, heavy-duty industrial paint, thinner, fuel oil, light oil burner.

主要产品有：沥青清漆、工业重防腐漆、稀料、燃料油、轻质烧火油。

As the first large-scaled and integrated oil sand project in the world, GCOS is well equipped with both mining and extraction/upgrading capacities, and started to process oil sand bitumen into synthetic crude oil.

作为世界上第一个大型油砂综合项目，GCOS拥有完备的露天挖掘和提炼改质的能力，并开始尝试将油砂沥青加工成合成原油的工作。

Gasoline, kerosine, fuel oils, Lubricating oils, waxes, asphalts, and the like are excluded from the definition of petrochemicals, since they are not, in the true sense, chemical compounds but are in fact intimate mixtures of hydrocarbons.

汽油、煤油、燃料油、润滑油、石蜡、沥青以及诸如此类的产品不属于石化产品。因为，从严格意义上说，它们不是化合物，而是烃类的均质混合物。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
