The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。

New ideas and methods in the paper:1 The formulas on perforated casing collapse strength were deducted, which offereda convenient method to analyze the relationship between casing collapse strength and perforation;2 The stress and displacement formulas on the system of casing, cement anddeformation under the non-uniform load were deducted, which offered the theoretical found for designing optimally casing string;3 The relationship between structure in-situ field of whole oil field and casing failurewere studied, which offered the scheme for the prediction of casing failure. The process of study in the paper:1 For simulating the relationship between the structure in-situ field and the casingfailure in the oil-deformation, the tests of the uniaxial tensile, compress, tnaxial compress and dilatability were made on the samples of the drill cores from deformation of casing failure position in Yuejing II oil field.

本文的主要创新： 1推导出了射孔套管抗挤强度的解析式，为分析射孔与套管强度的变化关系提供了简便的方法； 2推导出了非均匀地层载荷作用下套管、水泥环和地层组合体的应力和位移解析式，并非均匀作用下套管柱优化设计提供了理论依据； 3研究整个油田区块构造应力场与套管损坏关系，为预测套管损坏提供了可行方案；本文的研究过程如下： 1为模拟构造应力场与油层段套管损坏关系，做了大量的岩石单轴抗拉、单轴抗压、三轴试验以及岩石遇水膨胀试验，获得了研究区块岩石的弹性模量、泊松比、内聚力、内摩擦角以及岩石的线膨胀系数，这此数据为本文研究油层段套管损坏机理研究的理论分析和有限元法提供了实验数据。

There are a great many L-shape structures in modern designing, which induce stress concentration and singularity. The dependence of the discretization error on the mesh refinement of such structures of fillet and connection point is of particular evidence.

结构设计中广泛存在L-型结构往往导致应力集中和应力奇异性，有限元离散过程很大程度上影响了L-型结构角点附件的位移和应力数值解精度。

Typically, changes in output are achieved by varying the displacement of the engine (often through use of a arrangement), or by changing the quantity of working fluid, or by altering the piston/displacer phase angle, or in some cases simply by altering the engine load.

通常情况下，改变输出所取得的位移不同的引擎（通常是通过使用一种安排），或改变的数量，工作液，或通过改变活塞/置换相角，或在某些情况下只需通过改变发动机负荷。

When creating the finite element model, complicated connections among howitzer components are considered, especially the large displacement slide and the nonlinear spring connection between gun tube and cradle rail. The gun firing at 0°direction angle and 0°elevating angle is simulated with explicit time integration method and implicit time integration method, and the similar results are obtained.

在建立有限元模型时，考虑了火炮各部件间复杂连接，尤其是身管与摇架导轨间的大位移滑动接触和非线性弹簧单元连接等非线性问题；分别应用显式积分程序和隐式积分程序模拟了火炮在0°高低射角、0°方向射角工况下的发射过程，得到了相近的结果。

Test results show that Taichung Harbor Sand/ concrete block, the interface friction angle and shear strength are difference, related with the size of the grid opening, the grid number of horizontal opening, Soil and the geogrid system has more obvious acts, such as the shear stress to the displacement of shear increases, the interface will increase friction angle.

试验结果得知在上盒台中港砂/下盒混凝土块体，其影响界面摩擦角与剪力强度差异是与格网横向勒条数，开孔大小有关格网横向勒条数越多且网目越小，土壤与格网互制行为越为明显，剪应力将随著剪力位移的增加而增加，界面摩擦角将会提高。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
