The main characteristics of formation are :the salt formation is so developed that may reach about to 3000 meter thickness in Permian above main area of salt dome .

肯基亚克盐下油田的主要地质特点是：下二叠系盐层发育，在盐丘主体部位钻井，盐层厚度可达 30 0 0m ；石炭系灰岩油层孔隙压力系数高达 1。

The XRD and scanning electron microscopic results show that when the volume ratio between H_2SO_4 and H_3PO_4 is 2:1,the oxidation and intercalation effectiveness will be best,and the expanding volume gets to 102 mL·g~(-1).The energy dispersive X-ray spectrum analyses and the Fourier transform infrared spectra indicate there could be H_3PO_4,H_2SO_4,dihydric phosphate and sulphate containing Mn in the layers of EG.

XRD与扫描电子显微镜结果表明，当硫酸与磷酸体积比为2：1时，氧化-插层效果最佳，膨胀体积达到102 mL·g~(-1)。X射线能谱分析与傅立叶变换红外光谱分析显示，EG片层中可能插入了磷酸、硫酸以及Mn的磷酸二氢盐与硫酸盐等物质。

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。

Due to this, our goal is to develop a new method to functionalize implant surface by plasma treatment. Argon plasma removes all chemical traces such as adsorbed contaminates and impurities. Oxidation in oxygen plasmas by ion bombardment results in a dense oxide layer.

因此，本研究利用低温电浆来发展一植体表面处理技术，先以氩气电浆清洁钛金属表面，再以氧电浆让钛金属表面产生一层致密的二氧化钛层。

The high-performace liquid chromatographic method was developed for determination of Aloin and Isobarbaloin in rabbit blood. A HPLC system equipment, a Merk LiChrospher 100 RP-18e column with the mobile phase consisted of methanol-water (50:50) and UV detection wavelength at 359nm. The internal standard was 7-hydroxycoumarin and follow rate was 1.0ml/min.

并首先开发出在家兔体内血浆中二个指标成分之高效液相层析分析法，使用Merk LiChrospher 100 RP-18为层析管柱，移动相为甲醇与水（50：50），内部标准品为7-羟基香豆素，在检测波长359nm，流速1.0 ml/min下，分别定量血浆检品与进行确效性的评估。

The paper adopts some methods such as gas composition, carbon isotope, systematical analyzing and testing of reservoir bitumen biomarker from high evolutional natural gas and quantitative calculation of mixed gas, illustrates that natural gas from the section Ⅱ of Jialingjiang formation is mainly attributed to sapropel type organic matter gas of Permian, comes from carbonatite hydrocarbon rocks Permian which most of them are overmature, its main gas source has nothing to do with carbonatite hydrocarbon rocks of Jialingjiang formation themselves, presents in geochemistry characteristics of oil type cracked gas.

摘要通过对川中－川南过渡带西部的磨溪－潼南地区嘉二段天然气组成、碳同位素组成、高演化天然气储层沥青生物标志化合物的系统分析测试和混合成因气的定量估算，阐明了该区嘉二段天然气主要属于二叠系腐泥型有机质成因气，来源于二叠系过成熟为主的碳酸盐岩烃源，主力气源与嘉陵江组自身的碳酸盐岩烃源无关，并具有油型裂解气的地球化学特征。

Decarburized layer appears in the two sides of the crack.

裂纹两侧出现了一定宽度的脱碳层，脱碳层内部出现了二次氧化产物。

Example two analyzes the static construction character steel frame, braced frame and different braced frame, including relation of loading-level displacement, inter梥tory displacement and distribution of plastic hinge, the frames ductility, the axis force of brace and shearing-force of ground brace bearing, then it is clearly known the brace can minis the level displacement of frame, minis inter-story displacement, bear ground floor shearing-force. So, the brace greatly inflects construction performance of braced frame .

算例二对纯框架和支撑框架以及支撑框架不同支撑情况下进行非线性弹塑性分析：包括荷载—水平位移关系，层间相对位移与塑性铰分布，刚架延性，支撑轴力及底层支撑承担剪力等情况，了解到支撑可以减小框架柱顶水平位移，减小层间相对位移，增加刚架延性、承担底层剪力，显示支撑对框架结构性能的重要影响。
