IMPORTANT! Flow must always be in direction of arrow on valve body.

重要提示！水流流向必须与阀体上的箭头方向一致。

The two-fluid model and mixture k-ε turbulence model were adopted to describe the water-air two-phase turbulent flow.

根据掺气水流的特点，重点对相间阻力模型进行了改进，特别在构建相间阻力本构关系式时考虑了湍流扩散的影响。

Due to the cooling-water tube diameter of the generator is too small, the velocity of cooling-water is also too low, if we only use the travelling period difference of one emmission and reception, the propagation time will be too small to test. Then, we select ultrasonic circulation method as our concrete plan.

由于发电机冷却水引水管的管径小，冷却水的水流速度低，利用单次发射和接收的时间差检测时，传播时间差极其微小，故作者首次提出利用声循环法来检测大型汽轮发电机定子线棒冷却水流速。

Under the condition that lengthway's current velocity is 2.5 m/s,surface gradient is 0.2‰ and slack-water ship speed is 3.0 m/s,the relationship between current resistance and thrust push of the push tug at the transitional reach outside entrance of navigation lock is analyzed,and the requirement that the ratio of displacement tonnage to power should be less than 9.52 t/kW is put forward.

针对枢纽船闸口门外连接段航道，在纵向流速2.5m/s、水面比降0.2‰，以及船队在静水航速3.0m/s的条件下，分析船队推轮推力与水流阻力的关系，提出船队排水量与推轮功率比值应满足≤9.52t/kW的要求。

In the water, this feels like a tide a boat must fight against, an unusual current.

而在水里，感觉就像是必须和波涛做搏斗的小舟，这是不一般的水流。

He said it very lightly, like throwing the knife holder into the river and let it flow away.

他说的这句话很轻，就像刀柄扔到了河水中，随着河水流走了。

Three-leaf winding wing will whirling along with the friction of water and the laundry, it is efficient to decrease the possibility of ruffling cloth as washing by hand.

&三叶旋风翼&会随着水流和衣物的摩擦而转动，如同水洗一般，能有效地减少洗衣时导致的皱褶。

Confirm the establishment quantity and erection site of on-the-spot warning devise, such as the manual alarm button with telephone jack、indicator of rivers and hydrant button of fire prevention and so on, and also fire broadcasting system and fire telephone system.

确定带电话插孔的手动报警按钮、水流指示器、消火栓按钮等现场报警设备以及消防广播、消防电话的设置数量和安装位置等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
