Eastern Himalaya Syntaxis is an important area in studying climatic-tectonic reciprocity. In this paper, single-crystal-high-precision laser ~(40)Ar/~(39)Ar method was used to build the thermal evolutional history of Eastern Himalaya Syntaxis by tests on river sediments on the lower reach of Yalung-Tsangpo River. The contrast of age statistical results against the figure showing the changes in rate and angle of convergence during India plate has been colliding against Eurasian plate since late Mesozoic and the diagram consisting of global deep-seaδ18O andδ13C records is done, for the purpose of revealing climatic and tectonic information on rock cooling and referring the relationship between thermal evolutional history and climate and tectonics.

东喜马拉雅构造结是气候与构造相互作用的典型地区，本文尝试使用单颗粒高精度单次全熔~(40)Ar/~(39)Ar法对采自雅鲁藏布江大峡谷下游墨脱县城以南约50 km处地东河段的细粒现代河沙进行年代学测试，建立东喜马拉雅构造结的热史演化序列，并通过与代表全球气候变化的18O、13C浓度变化曲线和印度大陆向北运动的速度、角度变化曲线的对比，揭示气候、构造因素与东喜马拉雅构造结热史演化的耦合，推定热史演化与气候、构造过程的关系。

This paper introduced the development of persistent organic pollutants in the world, and described the distribution of persistent organic pollutants in typic area of our country, PAHs in middle and lower reaches of huai river was higher, and DDTs and PCBs were higher in Dalian lough than that in outer areas.

介绍了国内外持久性有机物的研究进展，分析了中国典型地区中的持久性有机污染物的分布情况，其中淮河中下游的PAHs含量较高，而大连湾检测出的DDTs和PCBs含量均高于其他地区。

Over the same period, the other three typical regions of the growth rate of second-hand housing turnover, respectively, CBD area is 92%, 55% Wangjing area, 60 percent of Zhongguancun area.

在同一时期，其他三个典型地区的增长率二手房成交，分别是生物多样性领域的92 ％， 55 ％的望京地区，百分之六十的中关村地区。

Unlike the previous ones, this essay which emphases more on quantitative and empirical analysis uses plenty of data, questionnaires and surveys, and typical surveys in typical regions, in order to reach more convincing and examinable conclusion, especially for the studies of the issues of migrant workers and the household registration system.

第二，由于受数据资料的限制，以往学术研究主要是通过规范分析的方法，定性的方法得出分析结论，本论文则以大量的数据、社会问卷调查以及典型地区的典型调查等方式为基础，侧重于定量和实证分析，从而所得出的结论更具说服力，可检验性强。

In this project, we have deduced the joint inversion model of geodetic data, seismic data and geological data considering about their weight ratio; presented Bayes-iterative search inversion algorithm which improved on the traditional Bayes algorithm and strengthen the stability of inversion solutions; enriched and developed geodetic joint inversion theory and method of tectonic stress field; joint with geodetic, seismic, geological and geophysical data, we have inverted the temporal and spatial variation characteristics of crustal deformation of active tectonic blocks in North China and the present-day cruatal movement and strain-stress field by FEM, DDA and bi-cubic spline function fit method; especial for the crustal deformation result in some typical areas, we have presented geodynamical interpretation and done some seismic dangerous estimations.

大地测量联合反演构造应力场属于大地测量与地球动力学和地震学的交叉研究领域，主要内容是研究用大地测量地壳运动监测数据定量研究地壳运动和变形的动力学问题及分析预测地震，本项目推导了兼顾权比确定的大地测量、地震和地质三类数据的联合反演模型；提出贝叶斯-轮回搜索反演算法，改进传统的贝叶斯方法，改善反演解的稳定性；丰富、发展了大地测量反演构造应力场理论及方法；联合大地测量、地震、地质、地球物理数据采用有限单元法、块体不连续变形分析法和双三次样条函数拟合方法反演分析了华北地区活动地块运动时空变化特征以及中国大陆现今地壳运动与应变-应力场，对典型地区地表形变结果进行地球动力学解释并进行地震危险性估计。

In this area, there is also observed the occurrence of Neoproterozoic diabase and hypabyssal, composite intrusive rocks of alkalic feldspar granite. The volcanic rocks and intrusive rocks have close spatial association and close age.
