不接触的

On the basis of the idea of partition of unity, a discontinuous function and the two-dimensional asymptotic crack-tip displacement fields are added to the displacement interpolation formula to account for discontinuity of the contact surface and stress singularity near the contact surface tip respectively. Governing equations are deduced by virtual work principle and the integral of the discontinuous functions are calculated by Gauss integral through sub-elements cut by discontinuous surface.

该方法基于单位分解思想，在位移插值形式中引入不连续函数和裂尖渐近位移场函数分别反映接触面的不连续性和接触面端点的奇异性；根据虚功原理建立有限元支配方程，接触面不连续函数积分采用分区高斯积分的方法。

对分光板和补偿板不严格平行、两反射镜相互不垂直、入射光与反射镜不垂直、螺杆顶块与移动镜接触定位块之间的松动或磨损等问题，进行了简单的分析和处理。

Axis: shorten distance between shafts to postpone the longevity of bearing and mechanism sealing; total seal, non-contacting with medium, rustless; need not adjusting when installation; serialization design, high generalization degree.

轴承体及轴承：拆卸方便，有足够的空间用于维修保养；泵体、泵盖、密封室轴承体浑然一体，精美大方。轴：缩短轴间距，以延长轴承和机械密封的使用寿命；完全密封，不与介质接触，不锈蚀；装配时不需调整；系列化设计，通用化程度高。

The rabbinic me'mra,' hardly more than a reverent substitution for the divine name, is not sufficiently substantial a concept; nor is direct contact with Hermetic circles likely.

该rabbinic me'mra ，'难多reverent替代，为神圣的名字，是不是够可观一个概念，也不是直接接触密封界可能。

As the board raises and spins, keep contact with the board with the side of your big toe.Rather than slapping the tail and lifting your foot away, lift your back foot straight up and "through" the board, so your toes will flip it on the way up.

随着板的抬升和转动，后脚脚尖保持和板接触，而不要用力击板尾离开板，后脚尖向上抬时要沿着板边缘轻轻地滑过，不是踢掉，也不是甩出。

In contrast, some items are very poisonous, but not the content, such as muscarinic, nitrite and pesticides, toxic poison, cyanide, etc., needles and their contacts, the response will not appear black.

相反，有些是很毒的物品，但却不含硫，比如毒蕈、亚硝酸盐、农药、毒鼠药、氰化物等，银针与它们接触，也不会出现黑色反应。

It has gone through three stages:Singapore had established commercial relations with China and recognized The People's Republic of China but refused any political contact;It had constructed practical political relations with China and developed all-round trade relations and economical cooperation but reluctated to establish diplomatic relation;It has set up normal diplomatic relations with China,strengthened and deepened their cooperations.

受国内国际因素的影响，新加坡对华政策经历了三个演变阶段：发展对华贸易，承认新中国，但不与中国进行政治接触；发展对华实质性政治关系，全面发展对华经济贸易关系与合作，但不急于与华建立外交关系；同中国建立外交关系，加强对华合作，全面拓宽、深化对华关系。

The conveyed medium can't be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. 5、No electricity. It's safe and reliable while using in the flammable and explore places. 6、It can be soaked in medium. 7、It's convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once over-loading, the pump will automatically stop and possesses the self-protection function. When the load recovers normally, it also can start automation. 8、Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc. 9、It can transmit the adhesive liquid (the viscosity is below 10000centipoise) 10、 This pump needn't the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.

所以抽送有毒、易挥发或腐蚀性介质时，不会造成环境污染和危害人身安全； 5、不必用电，在易燃、易爆场所使用安全可靠 6、可以浸没在介质中工作 7、使用方便、工作可靠、开停只需简单地打开和关闭气体阀门，即使由于意外情况而长时间无介质运行或突然停机，泵也不会因此而损坏，一旦超负荷，泵会自动地停机，具有自我保护性能，当负荷恢复正常后，又能自动启动运行； 8、结构简单、易损件少，该泵结构简单，安装、维修方便，泵输送的介质不会接触到配气阀，联杆等运动部件，不像其他类型的泵因转子、活塞、齿轮、叶片等部件的磨损而使性能逐步下降； 9、可输送较粘的液体（粘度在1万博以下）； 10、本泵无须用油润滑，即使空转，对泵也无任何影响，这是该泵一大特点

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
