The metastable phase equilibrium of the quaternary system Na(superscript +)∥Cl(superscript -), CO3(superscript 2-), B4O7(superscript 2-)-H2O was studied at 273 K by isothermal evaporation method, the solubility and density of the equilibrium solution of this system were determined and the metastable equilibrium phase diagram was plotted in line with the experimental data. The phase diagram of the system consists of three univariant curves, three crystallization fields and one invariant point.

Tectonization effects on Aran anticline exhibited as the follows: Aran anticline begin form rudiment in Ml member of URF; stronger compressive aggrandized extent of uplift in M2 member of URF; the strongest Tectonization aggrandized ultimately extent, especially in curvature of Aran anticline in later Quaternary sediment, Aran anticline finalized the design.

晚阿尔卑斯构造运动对Aran背斜地区的具体影响为：上红组M_1段沉积末，Aran背斜已经形成雏形；M_2段开始沉积到结束，构造挤压活动强度有所加大，Aran背斜隆起幅度相对有所增大；第四系以后发生了一次强烈的构造运动使Aran背斜的褶皱幅度、特别是曲度明显的加大，至此Aran背斜基本定型。

Based on palynological records of the Qangzê section in Zanda basin, Ngari, Tibet, the authors have preliminarily defined the Neogene-Quaternary boundary in the area and revealed the vegetational and environmental history of the area since the late Pleistocene.

摘 要：通过对西藏阿里札达盆地香孜剖面的孢粉分析，初步定出该地区新近纪和第四纪的界线，并得到更新世晚期以来该地区植被与环境发展的历史。

Find information about the protein's secondary, tertiary, and quaternary structure using database sites such as the Protein Data Bank or SCOP.

用数据库站点如Protein Data Bank和SCOP，找出此蛋白质的二、三、四级结构。

The basin subsided so cosmically that led to deposite the thick mudstone of Quaternary.Although there were two-times hiatuses,the period was short and the reservoir pressure didn't escape.Furthermore,the depth subsided again didn't excess the original depth,which resulted in the formation of overpressured reservoir.

盆地发育中表现出大套的第四系泥岩沉积，虽然区域储层顶部出现过两次沉积间断，但间断时间均较短，未造成油藏泄压，加之再次下沉的深度未超过储层的原沉积深度，最终形成盆地性的超高压油藏。

The promising regions for Quaternary biogas accumulation and location should meet all the following requirements: adequate biogas source, long time traps, good mothballing conditions and their good association. The Sebei and Tainan areas in the north slope of the Sanhu area are favorable direction of gas migration and should be regarded as targets of next exploration.

充足的气源供给、长期存在的圈闭、良好的封堵条件及其配置良好的区带是第四系生物气藏形成与分布的有利区带，例如该区北斜坡的涩北和台南地区为第四系生物气运移和聚集的最有利区带，易形成大气田，应作为下一步勘探的重点。

Then, basing on the practical problems of the studying area-the thickness of aquifer is little, the capability of depositing water is finite, the Quaternary loose stratum directly superimposes the bedrock strong breeze girdle, the writer thinks it is difficult to answer for the water use of the polyvinyl chloride project by the centralized tube well pumping.

根据研究区含水层厚度小、储水能力差，第四系松散层直接叠加在基岩强风化层之上的具体特点，认为管井集中开采难以满足聚氯乙烯工程的需水量要求，采用集水廊道最大限度地激发河流对地下水的补给，是在这一地区获得较大开采量的有效方式。
