In the Early Cambrian, the Tarim area was mainly a carbornate platform, in which there were penebanks, dolomitic flat, and gypsum-halite lake.

在早寒武世，塔里木地区是一个碳酸盐岩台地，其中散布着准滩、云坪和膏盐湖。

But, if the produced CO2 could not elute in time, carbonate would form during pyrolysis, and a calcined temperature higher than 800C was needed.

然而若焙烧过程中产生的CO2不能及时地排出，会导致体相中碳酸盐的形成，从而需要高于800C的再焙烧才能获得纯相的LSCO粉体。

Because the main territorial cap rock which could block off hydrocarbon migration in another side of fault in Paleozoic stratum is huge thick mudstone in upper mbr of Shangshihezi group and Shiqianfeng group, this make only backward fault to dip direction can block to form fault-block trap in the reservoir stratum of carbonatite eluvial horizon in Ordovician and thick sandstone in Permian .

古生界具有侧向封堵条件的区域性盖层主要是上石盒子组上段—石千峰组大套泥岩，这决定了断块区奥陶系碳酸盐岩风化淋滤带及二叠系大套砂岩储层在反向断层遮挡下能形成断块圈闭。

The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

丙烯氧化反应体系的原位漫反射红外光谱研究结果表明，由丙烯脱氢生成的烯丙基中间物种吸收峰在1454cm~(-1)和1427cm~(-1)处；基于此提出了较完整的丙烯氧化反应网络：丙烯选择氧化生成丙烯醛主要经历丙烯脱除甲基上的一个H，生成烯丙基物种，该物种嵌氧生成σ-O络合物，脱氢得到丙烯醛前驱体，脱附生成丙烯醛；完全氧化产物是由催化剂表面上生成甲酸盐、羧酸盐、碳酸盐等形式的中间物种转化而成；较低反应温度下丙烯氧化生成丙酮，通过烯醇式中间物种氧化生成丙酮前驱体得到。

The rock types include limemud limestones, bioclast limestones, oolites, intraclast limestones and dolomites, indicating a typical set of epeiric sea carbonate platform or submerged platform deposits.

岩石类型包括泥晶灰岩、生物碎屑灰岩、鮞粒灰岩、內碎屑灰岩、白云岩等，为一套典型的臺地或沈没臺地型陆表海碳酸盐沈积。

Basing on the analysis of epicontinental sea carbonate platform sequence stratigraphy of Cambrian in north China, the paper puts forward 6 points which shall be noticed on the study of sequence.

根据对华北地台寒武系陆表海碳酸盐台地层序地层分析，提出了露头层序工作的方法以及应注意的六项问题。

Pearl River Mouth Basin, an epicontinental sea and marginal sea basin, is one of depositional basins abundant in oil and gas in China.

该沉积组合反映了张性边缘海盆地的演化特点，盆地演化与资源效应表现在裂陷期、热沉降期及断块升降期的生储盖配置，故勘探目的层段为热沉降阶段所形成的三角洲碎屑岩与陆棚碳酸盐岩。

We understand that (1) releasing gases are mainly made up of CO 2 and alkane gases, and have a little ethylenic gases. There is a gas releasing peak at the temperature of 300～400℃ and the content of C 4～C 6 increases with temperature ri...

二氧化碳随温度的升高释放量增大，主要为碳酸盐分解贡献；(2 )含碳气体碳同位素随温度的升高增重，在气体释放峰温度段 350℃左右时发生明显&转折&，碳同位素组成明显变重，结果造成在不同的热演化阶段碳同位素值有较大范围的变化。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
