With the automatization of degree have improved in the industry, the demand of the mechanism continuity and security also have increased, the reason that cause the operation of mechanism to invalidation is the wear by the friction, which abrade the movement component and joint component.

随着工业自动化程度的提高，对机械零件工作的连续性、安全性要求也提高，而实践证明，导致机械运转失效的主要原因是由于活动构件或者联结件在摩擦力的作用下产生的磨损，磨损导致机械的运转失效，更可能引发安全隐患，这其中磨料磨损占整个磨损总量的50％，故越来越多的研究者对抗磨料磨损的材料进行了一系列的研究。

With the freedom in adduction and abduction motions of shoulder joint, a two-rigid-body motion system is formed.

将前臂和肱骨的联结简化为转动副，同肩关节的内收-外展自由度一同形成一个2自由度的两刚体系统。

Maine's chapter on primitive society and ancient law, will see from the terms of our proposition, that we have not altogether adopted his view that agnation at one time or other prevailed everywhere in the advancing communities ; but it is beyond dispute that its prence was most general.

这种制度，因为它长期流行于罗马，可能最好用罗马法学的术语来解释——其实它的名称也是属于罗马法学的。它的一般描述是它只包含通过男性的血统联结。

Diesel engines have the advantages of high thermal efficiency, maximum torque output, better fuel economic, and stability. In addition the diesel engine has an important contribution in dynamic machine, such as big truck, bus, trailer, attachment car, train, ship, agrimotor etc. It is excellent contributions to develop world economy, and then emissive smoke and NOx will produce air pollution to damage human health.

柴油引擎具有热效率高、输出扭力大及油耗较省、稳定又耐用等诸多优点，因此在动力机械方面始终扮演著重要的角色，如大货车、大客车、联结车、火车、船舶、农业机械等之引擎均采用之，对於全球经济发展功不可没；然而排放的黑烟和氮氧化物的浓度造成空气污染，影响人类健康，长期吸入会导致呼吸系统疾病，甚或致癌。

It was researched into the coupling form between three-row planetary gear train and shift restriction based on the matrix, and then the method of establishing mathematics model was presented for to analyze the planetary gear transmission by using MATLAB.

基于矩阵理论对行星齿轮变速机构的行星排之间联结、换档约束进行研究，提出用联结矩阵的组合形式建立三排行星机构传动型谱的概念，分析其所有可能的传动结构型式。

By self-explanation strategy, we can teach experimental subjects how to study and use examples in learning to solve physics problems, so metacognitive monitoring explanation strategy is a more well-advised means of physics learning than practice strategy, and the learning transfer level of subjects are also higher.?

实验结果表明：①以揭发意义或价值，建立新旧知识信息间实质性联结的解释策略对高知组和低知组的被试都具有明显促进物理问题解决的作用；以相似性、类比为依托的练习策略在学生头脑中建立的只是新旧知识间表面特征的联结，因而学习迁移的效果不如前者。

The lower seal coat used in construction usually has two functions,connection for penetration and protection for seal coat. It is of great significance to have connection layer between base layer and surface layer during the pavement construction in the northern parts of China.

我们在施工中所采用的下封层往往都具有双重作用，既要有透层的联结作用，又要有封层的保护作用，因此在北方路面中基层与面层间设置联结层具有十分重要的意义。

Waterproof functions and construction of prime coat and sub- seal coat of expressway;2. The lower seal coat used in construction usually has two functions,connection for penetration and protection for seal coat .

It is shown that the contact interaction enables bottom drillstring to whirl backward, and then an alternate bending stress with higher frequency is produced. So the drillstring fatigue failure could be accelerated. At the same time, a quite strong wallop force of high frequency is produced on the contacting point, and the contacting zone is next to the screw coupling of drill collars. It will easily result in the failure of screw couplings. The research results provide theoretical basis for the prevention of drillstring failure.

研究表明，下部钻柱与井壁的碰摩作用使下部钻柱反向涡动，产生高频的交变弯曲应力，会加速下部钻柱疲劳破坏；下部钻柱与井壁接触点处存在较大的高频冲击力，并且接触区域靠近钻铤螺纹联结处，更容易诱发螺纹联结处失效，该研究成果可为预防钻柱失效提供理论依据。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
