使循环

If the valve indicator doesn't give a clear indication whether it is open or closed, the rules prohibit repeated cycling, to avoid the possibility of having it potentially get stuck in a closed position, which would make detanking the shuttle more difficult and time-consuming.

如果阀指示灯不给予明确说明是否打开或关闭的规则禁止重复循环，以避免因它有可能会停留在一个封闭的立场，这将使detanking航天飞机更为困难和时间的可能性耗时。

Impeller rotates clockwise, the right part of the space between two blades is gradually increasing, in confined conditions, with the air volume increases, pressure decreases, the formation of vacuum pumps and air through the pipeline suction tube into the vacuum pump the right side of the crescent-shaped shell inspiratory mouth to be sucked into vacuum pump, vacuum pump impeller left some space between the two blades is gradually reduced, so the air is compressed, the pressure then increased, and finally through the vacuum pump shell crescent-shaped exhaust port from the left side of vacuum pumps, gas separator into the water box, so that was taken out after the separation of the recycled water reuse.

叶轮顺时针方向旋转时，其右半部分两叶片之间的空间逐渐增大，在密闭条件下，随着空气体积的增大，压力随之降低，形成真空，水泵和管路内的空气通过吸气管，进入真空泵泵壳右侧的月牙形吸气口被吸入真空泵，真空泵叶轮左半部分两叶片之间的空间是逐渐减小的，因此空气被压缩，压力随之增高，最后通过真空泵泵壳左侧月牙形排气口排出真空泵，进入水气分离箱，使被带出的循环水分离后再重复使用。

GK31030型高速中厚料三针绷缝机采用齿轮泵内循环自动润滑系统和可靠的密封方式，能保证在高速时的正常运转和衣料的洁净。装有独特的移动护针机构和上轴外支座，使其增强了缝厚能力。具备基本缝、单边压平缝和拼接缝的双面装饰缝纫功能。

Stretching is a major piece of the foundation of health for a number of reasons: it improves flexibility, it makes other exercises easier, it improves range of movement, it reduces muscle tension, it improves circulation (which directly relates to improved energy levels), and it improves muscular coordination.

基于以下这些理由，伸展运动是健康基础的一个主要组成部分：它可以改善柔韧性，使进行其他锻炼活动变得更加容易，扩展动作的范围，缓解肌肉的紧张，促进循环（从而直接提升了能量等级），改善肌肉功能的协调性。

A self-reformation may bring about a fine circulation of vocational education, and thus increase the competitiveness of secondary vocational schools and may further make vocational education more attractive in the society.

The mixing power and circulation characteristics of Newtonian fluid and pseudoplastic fluid were measured in a φ300mm organic glass vessel,by using anchor and tri-leaf impeller,anchor and inner-outer screw,orthogonal twi-stratm triangle blades and single screw,orthogonal twi-stratum triangle blades and inner-outer screw types of combined agitators.

为使聚合釜内搅拌介质在湍流、过渡流及层流域都能达到良好的混合，对锚－三叶推进器、锚－内外单螺带、正交双层三角桨－单螺带、正交双层三角桨－内外单螺带等4种组合桨搅拌器，于φ300mm的有机玻璃釜中，测定了在牛顿流体和假塑性流体中的搅拌功率和循环特性。

Scanning electron microscope and atomic force microscope revealed that ruthenium oxide particles incorporated onto the nafion polymer film. RuO/Nf/GCE film modified electrode showed excellent electrocatalytic activity for the oxidation of dopamine and ascorbic acid.

本研究主要是使用循环伏安法使氧化钌稳定沉积在Nafion修饰电极上，形成氧化钌/Nafion 薄膜修饰电极，利用电化学石英晶体微天平观察其在电极上的成长情形，旋转环碟电极法则是用来研究其电催化反应，并用扫描式电子显微镜观察氧化钌结合在Nafion聚合薄膜上的表面现象。

In fact, the loop she replayed in her head was the one thing standing in her way, since evidence disconfirming her hypothesis was everywhere.
