The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.

古近纪和新近纪成盐卤水的迁移和聚集、成盐作用的强弱以及整个含盐系的沉积发育明显受到上述构造活动的控制：含盐系的厚度随时间由北西向东、向南逐渐增厚，且厚度分布逐渐趋于复杂化；石盐岩的沉积规模和范围也逐渐向东扩大；古近纪早期和新近纪强烈的构造活动对于成盐作用而言是一种干扰因素，而古近纪中、晚期相对较弱、导致盆地缓慢持续沉降的构造活动对成盐，尤其对成钾作用则极为有利。

Density fractionation reveals that organic matter content is closely relevant to clay mineral content and mineral surface area in the salified Lake, suggesting that clay mineral adsorption is the major mechanism in the preservation of organic matter in sediments of the Qinghai Lake.

沉积物经密度分离后测试发现，有机碳含量与粘土矿物含量及矿物表面积之间具有很好的正相关性，说明粘土矿物吸附是青海湖底沉积物中有机质的主要赋存形式。

The research results indicate that the qualities of the Jurassic reservoir are dominated by construction. Good reservoirs lie to an advantaged nose protrusion, nearly relating to the distribution of sedimentary micro-facies. The reservoir that lies on the main position in the riverway has better gathering characters. Because argillaceous content is increase and the porosity and permeability became smaller, the character of the reservoir becomes bad in the flood plain area that lies on the skirted riverway and between riverways. Characters of the layer relate to the distribution of main sand-body that the better feature of the layer and the bigger thick of sandbody layer.

通过综合储层含油性、非均质性、分类研究的GIS 分析结果，研究认为：长西油田侏罗系储层性质受构造控制，储集性好的储层在区域上大多属于一个有利的鼻状隆起；且与沉积微相的展布密切相关，在河道主体部位的储层其储集性一般都较好，而在河道侧缘和河道之间的泛滥平原沉积区，泥质含量增加，孔渗性变差，储层的储集性也变差；储层优劣与主砂带的分布也有关，砂层厚度越大，储集性越好。

The deposition of Diexi ancient barrier lake in the upper reaches of Minjiang River was redated by AMS14C dating, and the result shows it started at 405 ka BP.

对岷江上游地区叠溪古堰塞湖底部沉积物进行AMS14C定年，得到其沉积时间起始时间约为405 ka BP。

The composite electroforming process of preparing nanometer alumina particle reinforced copper base composite material has phosphor copper plate as anode material, stainless steel sheet as cathode deposition body, nanometer level alumina particle as reinforcing particle, and fluorocarbide surfactant or formamide as co-deposition promoter.

一种纳米氧化铝颗粒增强铜基复合材料的复合电铸制备方法，用金属磷铜板作阳极材料，不锈钢片作为阴极沉积体，增强颗粒为纳米级氧化铝颗粒，采用氟碳阳离子表面活性剂或甲酰胺为共沉积促进剂。

The sand bodies formed under the mechanism of forced regression are mostly deposited in Qijia-Gulong depression, and the prograde towards the basin gradually.

强制性水退机制作用下形成的砂体大都沉积在沉积滨线坡折带以下的齐家－古龙凹陷内，并逐渐向盆地方向进积迁移。

Meanwhile, Longhupao-Da' an terrace west to the deposition is a sedimentary shoreline knick zone, 3 metasequence groups in lo-stand tract prograde from old ones to new, and coastal line migrate towards the basin accordingly.

研究发现研究区低位域地层沉积是在强制性水退背景下形成的，此时其西部的龙虎泡－大安阶地为沉积滨线坡折带，低位域内3个准层序组依次由老到新向盆地进积，滨岸线也相应的向盆地方向迁移。
