"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said. Remember that you are responsible for what you put in your circle and that circle will also touch many other circles.

他说："在生命的水面上，你也许能激起许多波纹，而你所激起的波纹也会打破别人的平静，"要谨记，对你所激起的波纹中所包含的东西负责，因为这些东西会接触、影响到别人的波纹。

"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said,"Remember that you are responsible for what you put in your circle and that circle will also touch many other circles."

"在生命的水面上，你可以溅起许多水花，而这些水花的波纹也会干扰到你周围众生的宁静。"祖父对我说，"记住，你需要对你所激起的波纹负责，因为它们会碰触到别人的波纹。"

The effects of elasticity of metal bellows on performance ofmechanical seals have been studied in detail for the first time, which has not been doneuntil now. Furthermore the relations between leakage rate, friction factor, wear rate andelasticity of bellows have been developed. These results have been verified by the teston the rig.

In usable length test, we have noted that there are some differences between the stretching and shrinkage behaviors of wall crimps under same pressure.

波纹化人造血管纵向顺应性的中测试即可用长度的测试，波纹在压力条件下展开和回缩存在差异，因此在测试时应特别注意加压的顺序避免由于波纹不能完全回复而引起的测试结果误差。

When temperature of the steam pipe goes up, the liquid volatilizes into gas, the size expands and produces pressure to impel bellows to stretch.

当蒸汽管线升温时，液体挥发成气体体积膨胀并产生压力推动着波纹管伸长，蒸汽管线降温达到易挥发的液体从气体转变成液体时体积缩收，波纹管内没有推动力，波纹管缩收。

In this paper, research is focused on the heat and mass transfer features during absorption process on the two-scale corrugation plate surfaces of plate-shell heat exchangers. This new Kind structure has vertical large corrugations and horizontal small ones, which can enhance the convection heat transfer of cooling water at internal plate channel side and make the liquid falling film uniformly distributed and turbulent by twisting path, so that the heat and mass transfer characteristics at both sides can be enhanced while sufficient flow area for adequate resistance requirement is also met.

本论文围绕一种新型交叉双尺度波纹板片组成的板壳式吸收器进行研究，这种新型传热元件的相邻板片的竖直大波纹相顶靠，形成曲折的板内通道和菱形板外通道，可强化板内侧冷却水的对流传热，而其水平小波纹则可对布膜的溴化锂浓溶液和冷剂蒸汽产生连续的扰动，使液膜分布均匀，传热传质得到强化。

Given the same total flow effusion from holes, the results show that the heat shield gets a higher average cooling effectiveness when the opening ratio is 3% compared with 6%; cooling effectiveness is sensitive to the height of ripple board, the heat shield gets the highest cooling effectiveness when the dimensionless height of ripple board is 1% compared with 2% and 3.33%; but there is a little influence on the cooling effectiveness of the liner with the change of the diameter of holes and the height of cooling passage.

研究表明：在气膜孔出流总量相同的情况下，3%开孔率比6%开孔率的隔热屏平均冷却效率较高；波纹板高度对隔热屏冷却效果影响较大，波纹板无量纲高度为1%比波纹板无量纲高度为2%和3.33%的隔热屏平均冷却效率高；孔径和冷却通道高度的改变对隔热屏冷却效果几乎没有影响。

BW-WJ universal angular corrugated compensator is made up of structures such as one (or more the two namely composite universal angular type) bellows, forelock, axis, hinge plate, universal loop and standing board etc. It can absorb angular displacement in any plane and bear the pressure or thrust of the bellows. When large compens-ation is required, two or more compensator can be assembled and utilized in series. Besides, the product can also be pre-pressed, pulled or reversed when installed.

BW-WJ型万向角向型波纹补偿器由一个（或二个及以上，即复式万向角向型）波纹管、销、轴、铰链板、万向环和立板等结构件组成，能吸收任意一平面内的角位移并能承受波纹管压力推力的膨胀节，当需要大补偿量时，可采用两个或以上组合分段串联使用，并对产品预压缩、拉伸或扭转安装。

From the view of coactions of both component of flow momentum and flow resistance in the direction of corrugations, the essential mechanism of the flow pattern in the channel between two chevron-type corrugation plates affected by corrugation geometric parameters was discussed.
