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。

As one of the common facilities in manufacturing enterprises, air compressors are widely used due to their capacity of producing compressed air. However , an authoritative survey shows that air compressor system consumes about 86%of the total energy cost within five years compared with purchase price that only accounts for 8% of total cost. This high volume of energy consummation invisibly increases enterprises' operational cost. However ,within the 90% of the cost for energy, main tenance and repair , 50% can be saved.

压缩机作为制造厂最常用的设备之一，其所产生的廉价适用的压缩空气能源备受许多企业家青睐，据权威机构调查，空气压缩系统在五年的总成本中，运转能源消耗费用占约86％，压缩系统初期购置费用仅占总成本的约8％，其高额的运转能源费用无形中增加了企业运营成本；然而人们却不知道这里占近90％的能源及保养修理费用却是有50％以上是可能不必支付的。

Article 38 Nuclear reactor operator means a person who operates or directs others to operate the control of a nuclear reactor.

第38条凡操纵或指挥他人操纵核子反应器控制装置者为核子反应器运转转人员，分运转员及高级运转员两种，其操作范围依左列规定

The results showed that N uptake of diploid andtetraptoid were lower than those of Hexaptoid and octoploid at over wintering and afteranthesis, but the capability was higher from jointing to anthesis. Diploid and tetraploid hadlower N distribution in leaf, and had higher N distribution in else vegetative parts at anthesis. And had lower N distribution in grain, higher N distribution in else vegetativeparts at mature. The N transfer amounts and its contribution to grain N accumulation ofDiploid and tetraploid were higher than Hexaploid, but the NTE and contribution of Naccumulation to grain N were lower.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料在越冬前和花后氮素吸收能力较低，在拔节到开花期间较高；开花期氮素在叶片中的积累较少，其他营养器官积累较多，成熟期营养器官中的氮素分配较高，籽粒中氮素分配较少；具有较高的氮素运转量，但运转效率比较低；花后营养器官氮素运转对籽粒氮素积累的贡献率较高，花后吸收氮素的贡献率较低。

Similarly, with movement of the wheel of time which is observed by the constellations and signs. They are moving to the right around Dhruva loka and Sumeru mountain and moving with them are the ant-like planets like the sun and other small planets. But because these planets are seen in different constellations and signs at different times, the motion of these planets is different from the motion of the zodiac or wheel of time.

同样的，时间之轮的运作也可以通过星座和黄道十二宫的运转来观察到，这些星座在右侧围绕着杜茹瓦珞卡和苏梅茹山转，跟着它们一起运动的还有许多相比之下象蚂蚁一样大小的星球，但因为在不同的时间观察星座和黄道十二宫，它们就处在不同的方位，众多星球的运转轨迹看起来和黄道十二宫及时间之轮的运转有所不同。

In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

本论文第二部分从速率方程出发，通过求解速率方程的稳态解得到了Nd：YAP腔内倍频双波长激光的连续运转条件，数值计算得到了随泵浦功率变化的激光运转情况；计算、分析了通过增加主波长的倍频耦合几何因子和增加主波长的腔内损耗两种方法获得均衡的双波长倍频输出的运转情况，通过二者的比较，发现增加倍频耦合几何因子的方法比增加损耗的方法效率更高，而且在实验上更易于实现。

Fourth, to avoid breaking material: Screw must not be allowed in the case of blanking operation, upon occurrence of the stator as dry friction of rubber, produces instant heat and burn, so good grinder, screw grille flow is a necessary condition for normal operation To this end, some screw pump body is also expected to stop off device installed, when there Fracture, because he has a self-priming screw pump function of the characteristics Chemical pumps of the body will produce a vacuum chamber, vacuum screw pump will stop operation.

四、避免断料：螺杆泵决不允许在断料的情形下运转，一经消防泵发生，橡胶定子由于干摩擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.

Screw does not allow for the case of run-off materials, once occurred, rubber stator due to dry friction, the heat generated instantly burned, so grinder intact, grille flow is a necessary condition for the normal operation of pumps, one of To this end, some screw pump is also installed in the body break down plant material, as occurs when the material off, because he has a self-priming pumps feature the characteristics of the body will produce a vacuum chamber, vacuum devices will screw pump to stop operation.

It is the collective efforts of individual dedications, and a group operation, a company running a functioning society, a civilized operation.

正是个人对集体的努力奉献，使一个团体运转、一家公司运转、一个社会运转、一种文明运转。

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。
