Fixing end of the strainer and the other end passes through the half-moon axis transverse groove.

半月轴横槽，通过反复摇动拉紧器的把手而达到张紧的目的。

The Levy style Cable Dome model is made up of 〓5 tension piano-wires and 〓32×1 5 compressive steel pipes, distance between nodes and the tension force of cables is adjusted by screw up and down the turnbuckle The procedure of shaping up included four ways, and the loading included fully loaded and half loaded, to validate the influence of unconservative property, the author carried through the slack procedure and the unload procedure.

该Levy型索穹顶模型，以受拉的〓5高强钢丝和〓32×1.5受压钢管构成，节点间拉索的长度以及拉索的预拉力通过拧紧或放松花篮螺丝来调节。试验内容包括成形试验和承载力试验，成形试验尝试了四种不同的成形方法，为了考察结构非保守性的影响，每种成形方法成形后，还逆序进行了结构的松弛试验，荷载态试验包括均布荷载满载（即在所有压杆上部节点施加集中荷载）和半载（在结构1／2的压杆上部节点施加集中荷载）的加载和卸载时结构工作性能的测试。

The RF electricity of ice adopts radio frequency technique of the RF dual pole. The frequency can make the water element of the cell which at the certain depth shake at a high speed, it can produce the quantity of heat at 45-60℃ through the quick circumvolved friction. Because the collagen fibre is shrinked, the wrinkle can be tighted. Then the light pyrolysis stimulates collagen and elasticity fibre to become more and arrange once again so as to reach the function of dispelling wrinkle and shrinking pore.

冰电除皱系统采用RF双极射频技术，发射的频率可以在皮下的特定深度内使细胞内的水分子产生高速震动，通过这种高速的旋转摩擦从而产生热量45-60℃，胶原纤维收缩，即刻松弛的皮肤、皱纹被拉紧，随后，真皮层中产生的热效应使胶原增生、重新排列、数量增加，同时修复老化受损的胶原，达到即刻紧肤、长效除皱抗衰老的效果。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸率直接体现在拉伸冲头和展开平板边缘之间的关系---拉伸冲头和展开平板边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和模具表面间有额外金属板表面被夹紧。试着用不同尺寸和外形的展开平板进行实验。

When cutting tool roaled of spindle's hole by manipulator or other ways,the pull nail behind of knife hilts is sent to ahead of tension bar of spindle. When receives the clamps signal, the pressure oil is passed over the oil cylinder left cavity of the spindle rear part, the piston to the right migration ,tension bar also to right migration by small dish shape spring function, the stell ball of ahead circumference of the tension bar shrink the distribution diameter by spindle's cone hole's force, holds on the knife hilts and pull nail colsely.

当刀具由机械手或用其他方法装到主轴孔后，其刀柄后部的拉钉便被送到主轴内拉杆的前端，当接到夹紧信号时，将压力油通入主轴尾部的油缸左腔，活塞向右移动，拉杆在碟形弹簧的作用下也向右移动，其前端圆周上的钢球在主轴锥孔的逼迫下收缩分布直径，将刀柄拉钉紧紧拉住。

The compulsory use of automatic retractors in seat belts from 1975, plus the availability of pretensioners that take up the slack in the seatbelt when a crash is sensed solved the first problem.

1975年自动预张紧安全带开始强制使用。在感受到碰撞时，预拉紧就避免了松弛带来的问题。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
