The present method is applied to two-dimensional potential problems and the corresponding discrete equations are derived. Because the shape functions so-obtained possess the Kronecker delta property, the essential boundary conditions can be enforced as the FEM; furthermore, the Heaviside step function is used as the test function, there is no domain integral, and only a regular boundary integral is involved.

因为滑动Kriging插值方法构造的形函数满足Kronecker函数性质，所以本文建立的改进的无网格局部Petrov-Galerkin法可以像有限元法一样直接施加边界条件；由于采用Heaviside分段函数作为局部弱形式的权函数，因此在计算刚度矩阵时只涉及边界积分，而没有区域积分。

The result showed that convex surface is tend to possess high anti-abrasion resistence in higher wear velocity, higher convex dome and without fillet between convex and base plane.

其分析表明，泥沙在较高滑动速度、较大凸包尺寸及凸包与基底无过渡圆角时凸包分布对自由式磨料磨损的作用更大，倾向于获得较轻的磨损。

In this method, all stable sub-intervals in the training sequence were located for each pixel as possible background. Then a classify data set was constructed by the median values of each subinterval. A background subset was obtained from the data set by unsupervised clustering. Accordingly the initialized background was obtained from the background subset.

首先利用滑动可变窗口检测每个像素的所有不重叠平滑子序列，获取可能背景；然后选择每个平滑子序列的中值样本点构建分类序列集，根据未知类别的无监督聚类识别思想获取背景子集，实现背景初始化。

Cylinder body endophragm and the live pump plunger shaft plate the hard chromium, has the very good abrasion resistance; Between all glide part has the oil-free lubrication axis and the guidance link reduces the friction coefficient, the extension service life, AW the air operated actuator U curved characteristic

输出扭矩大，动作灵活平稳；缸体内壁和活塞轴镀硬铬，具有很好的抗磨性；所有滑动部件之间配有无油润滑轴和导向环以降低摩擦系数，延长使用寿命，AW气动执行器的U型曲线特性输出扭矩更适用于大口径球阀、蝶阀。

Another six specimens of each group was obtained for biomechanical test at 8 weeks. RESULTS: There were no significant differences between control group and fibrin group. In bFGF group compared with control and fibrin groups, appearance of the angiogenesis, fibroblast proliferation and collagen production in the sheath, epitenon and parenchyma at repair site occurred earlier and were more in quantity, the gliding excursion of the tendon was shorter, and the work of flexion and the ultimate tensile strength of the tendon were greater.

结果：对照组与纤维蛋白封闭剂组间各项观测指标比较均无显著性差别，与对照组和纤维蛋白封闭剂组相比，bFGF组修复部位腱鞘、腱外膜及腱实质的新生血管形成、成纤维细胞增殖较好，胶原的分泌出现早，数量也较多；肌腱滑动距离较短，屈曲功和肌腱最大抗拉力较大。

Its subject coverage includes: composites from a wide range of matrix alloys, particulate sizes, and loadings; and wear processes also over a full range, including sliding, abrasion, erosion, and impact, etc., in both lubricated and unlubricated conditions.

它的主题涉及的范围包括：各类基合金合成物、颗粒大小与装入；全面的磨损过程，包括在润滑与无润滑条件下的滑动、磨擦、侵蚀与冲击。

Setting slide layer is a good measure to reduce the interaction between the rail and bridge, and rail expansion joint on long span bridge can be cancelled.

桥上纵连板式轨道借助底座板的纵连解决梁端转角对轨道结构的不利影响，通过设置滑动层来削减梁轨相互作用，在大跨桥上可以取消钢轨伸缩调节器，这种设计思想对大跨桥上铺设无砟轨道具有积极的借鉴意义。

According to the principle of elasticity-viscoelasticity, equations of stress and strainfor EMP surface layer under the load of different indenters and indenter contact whilesliding were calculated separately. The indenters contain sphere, cylinder and taper.

粘弹性对应原则，计算出了受一般外形压头法向无摩擦力作用下和受球、圆柱平头、圆锥形压头法向载荷作用下，以及在滑动过程中相应压头形态接触作用下EMP表层的应力、应变方程。
