Sulfide layer was made on the surface of high speed steel (W6Mo5Cr4V2) by means of low temperature ion sulfurization. The tribological properties of the sulfide layer under dry sliding were investigated on an MM 200 friction and wear test rig. An atomic force microscope and a scanning electron microscope equipped with an energy dispersive spectrometer attachment were adopted to analyze the morphologies and compositions of the original and worn surfaces of the sulfide layer. The phase structure of the sulfide layer was determined by X ray diffraction.

Thickish and dead colour mudstone in Nenjiang layer can generate huge amounts of oil and gas. Qingshankou layer is as good as Nenjiang layer, from which oil and gas can be moved to So-layer reservoir.

喇嘛甸嫩江组一段巨厚的暗色泥岩，可以生成大量的油气，因此为喇嘛甸油气自生部分油气，青山口组巨厚的暗色泥岩，也可以生成大量的油气，并可以运移到萨零油层。

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。

The order spatial variation of soil surface compaction was in the land reclaimed five years(68.40%), next was unsubsided land(52.58%) and the lowest was the land being reclaimed(22.01%); in terms of the variation, the soil compaction is higher and the variation is lower to each soil layer of being reclaimed land, and the compaction of the first three layer is lower but the variation is higher to other redamed land, to the fourth layer(22.86～30.48 cm) is higher and variation is lower, and the compaction under the forth layer is nearly stable.

表层土壤压实度空间变异最大的是复垦5 a的土地（变异系数为68.40%），其次是未塌陷土地（52.58%），最小的是正在复垦的土地（22.01%）。从各层的变异情况看，正在复垦的土地各个层次土壤压实度都较大且变异系数较低，其他复垦年限土壤压实度上面3层较小但变异大，至第4层（22.86～30.48 cm）达到较高值，且变异较小，之下压实度基本稳定。

There are many heaves and concaves which can be observed on the surface of the layer, and so they make the surface of the layer rough. The surface of the layer is rich in Ti, but gradually the Ti decreases. It shows that The combine of the layer with the base is good, which result from the heat diffusing and chemical metallurgy reaction.

涂层表面由许多凸起和凹坑组成，表面稍粗糙，这是脉冲放电的工艺特点决定；涂层内部Ti元素由表层至与基体界面处呈梯度分布，并且Ti元素也渗入基体一定深度，说明结合良好，为冶金反应和热扩散的结果。

The structure changing feature of refractory in corrosion process is that there are decarburizing layer and metamorphorsis layer. In order to increase the resistance to melt for refractory containing graphite carbon, the forming rate of decarburizing layer and metamorphorsis layer must be controlled efficiently.

在耐火材料表面存在一层渣膜，它的组成既不同于熔体，也不同于耐火材料组分，而是富集耐火材料中的某些组分的液态渣膜，它的组成和性质控制着耐火材料的侵蚀速度。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.

拱坝的地基一般是层状岩石地基，有的层厚度很小，这样就有多个岩层和坝体某层单元接触，本文根据岩基与坝体接触的几何关系，利用形函数的性质，提出24节点六面体层单元，这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的，其形函数采用可以拆分的形式表达，因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况，可以模拟一、二、三、四个棱边与错动带接触的情况，还可以退化为12节点的四边形面单元，以及五面体层单元。
