   2 )对新生代龙门山前陆盆地大邑砾岩岩相、沉积相和沉积环境进行了系统分析和研究，划分出6种粗碎屑岩相、 5种中碎屑岩相、 3种细碎屑岩相，确定了大邑砾岩为冲积扇相、河流相沉积环境的组合。
2. The paper analyzed sedimentary characteristics and depositional environment in t1f3 this region firstly , and on the grounds of establishing logical deposit pattern gave emphasis to make a study of distributing laws and spreading traits of the oolitic beach . because diagenesis is a vitally dominating factor that influenced oolitic beach reservoir nature in the region , the master diagenetic events of the reservoir in the lengthy geological history , as well as the influence to the pore abundance , was made a study of . the diagenetic stages and sequences were divided and the pore evolve pattern was established in the paper
   本论文首先分析了研究区飞三段的沉积特征与沉积环境，在合理建立沉积相模式的基础上重点研究了鲕粒滩(坝)的分布规律和空间展布特点；成岩作用是影响本区鲕滩储集性至关重要的控制因素，论文详细研究了储层在漫长地质历史过程中所经历的主要成岩事件及其对孔隙发育的影响，划分了成岩阶段与成岩演化次序，建立了孔隙演化模式并以建南构造为例进行了成岩相展布研究的尝试；最后还在鲕滩储层基本特征研究的基础上对飞三段储层进行综合评价与预测。
3. The researches of dynamic behavior and liquefaction potential of saturated sands have been further . however , more and more macroscopic liquefaction phenomena and experimental investigations show that different depositional environments lead to different structure of soils , while the influence of structure property of soils on liquefaction resistance is no less than that of density and consolidation stress and so on . ancient alluvial flat deposits , namely recently deposited soils , are easier liquefaction during earthquake
   对于一般饱和砂土的动力特性和液化势的研究已比较深入，然而，愈益增多的宏观现象和试验研究表明，由于土的沉积环境不同而导致土的结构性的差异，而土的结构性对抗液化能力的影响并不亚于密度、固结压力等因素，古河漫滩堆积物即新近沉积土在地震当中更容易液化。
4. The results are shown as the followings : on the basis of studies of depositional environment of source rock and its petroleum potential assessment , the biomarker compositions of the five source beds ( hq , j2k , jiy , tjt , tsh ) in kuche basin are analyzed in detail and the effects of depositional environment and maturity on the biomarker compositions are also discussed . the results show that there is not clear correlation between the distribution of biomarker composition and the ages of triassic and jurassic . it is proposed for the first time in the kuche basin that the changes of biomarker composition in the coal can be classified into three stages with the maturity , and the regular changes of different biomarker parameters in the coal are revealed
   以烃源岩沉积环境为背景，详细剖析了库车前陆盆地五套烃源层( j _ 2q 、 j _ 2k 、 j _ 1y 、 t _ 3t 、 t _ 3h )中煤、炭质泥岩、湖相泥岩、煤系泥岩的生物标志物组成特征，分析了沉积环境、成熟度对生物标志物组成的影响，指出同一烃源层在盆地不同地区生物标志物组成的差异，并认为生物标志物组成特征与三叠系和侏罗系的时代对应关系不明显。
