On the basis of systemic and embedded analysis of the sequence stratigraphy and basin, and combining with the factors of global sea level fluctuation, tectonic subsidence, paleoclimate change, terrigenous sediments filling and carbonate productivity, the dynamic model of sequence filling have been founded, which can be used to explain forming mechanism of special parasequence in studying area and ultimately give the definition of sequence filling dynamics.

在系统、深入的层序研究和盆地分析的基础上，结合全球海平面升降、构造沉降、古气候背景、陆源沉积物的注入和碳酸盐的产率等因素，分别建立了不同类型盆地的层序充填动力学模型，并根据这些模型对研究区特殊的准层序形成机理进行了解释，最后给出了层序充填动力学的定义。

For square and regularly triangular cross sections, a generic morphological transition sequence, from perpendicular lamellae to parallel lamellae to concentric lamellae or trifurcate lamellae is predicted with increasing the surface preference.

在截面为正方形和正三角形的纳米孔中，我们预测随着孔壁作用的增加，可出现从垂直层到平行层到同心层或三叉层的一系列形态变化。

The physical chemistry properties of evaporite beds in Bachu area are analysed.On the basis of the feature of salt beds,the undersaturation salt water drilling fluid is determined.

塔里木盆地复合盐层地层分布广，在不同构造的钻探中都钻遇盐层，盐层厚度一般几十米到几百米，岩性以盐岩与膏岩、泥岩、泥质粉砂岩等不等厚互层。

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。

The present invention relates to a halogen-free, multilayered, uniaxially oriented heat shrink film comprising a core layer comprising a blend of polyolefins; a first skin layer on the upper surface of the core layer, and a second skin layer on the lower surface of the core layer, wherein the first and second skin layers independently comprise a polyolefin blend and wherein the shrinkage of the film is at least about 40% in the machine direction at 270 DEG F.

本发明涉及一种不含卤素、多层、单轴取向的热收缩薄膜，包含含聚烯烃共混物的芯层；在芯层上表面上的第一皮层，和在芯层下表面上的第二皮层，其中，第一和第二皮层独立地包含聚烯烃共混物，并且其中，在270°F，在纵向薄膜的收缩率至少约为40％。

Contact configuration under unlubricated condition were investigated, with the effect of the nano-La_2O_3 content on the friction and wear behaviors of the composite coatings to be emphasized. The worn surfaces of the composite coatings were analyzed using a scanning electron microscope and compared with t...

结果表明，在干摩擦条件下，随着La2O3纳米颗粒含量的增加，纳米复合镀层的摩擦系数降低，耐磨性能提高；La2O3质量分数为3.1%的纳米复合镀层的摩擦系数最低，耐磨性能最佳；纯Ni镀层呈现严重的粘着磨损特征，而纳米复合镀层主要呈现轻微磨粒磨损特征。

It was found that PLZT was easily reduced and the thickness of reduced layer had a linear relationship with the reduction time; The optimal conditions for PLZT were determined to be 950℃ for 1~5 hours; Reduced PLZT was composed of reduced and unreduced layer obviously and the reduced layer was transgranularly fractured while the unreduced ceramic was intergranularly fractured; Metallic lead and refractor oxides (PbO, ZrO2, TiO2, etc.) were found in the reduced layer, however, the crystal structure of PLZT was not found.

研究表明，PLZT具有较好的还原性能，还原层厚度与时间有线性关係，理想的还原条件为：950℃保温1~1.5h；还原样品有明显的分层结构，还原层表现出穿晶断裂而未还原层则是沿晶断裂的特徵；还原层主要由金属Pb及PbO， ZrO2， TiO2等氧化物组成，原先的晶体结构已不存在。
