Connect joint of mechanical seal with shaft seal water pipeline (For newly installed shaft seal water pipelines, please clean up or rinse out sundries such as welding dregs, sand which are remnant in pipelines in advance). Start shaft seal pump, unclose shaft seal pipeline valve and turn pump shaft by manpower, if leakage, that indicates dunghill exist on shaft seal end-cover, here gland bolts should be loosened to wash mechanical seal with clean water and then impact gland.

将机械密封的接口连通轴封水管路(新安装的轴封水管路应事先将残存在管路内的焊渣，泥沙等杂物清理或清洗干净)，启动轴封泵，打开轴封水管路阀门，人工转动泵轴，如有滴漏现像说明轴封端面有脏物存在，应将压盖螺栓松开用清水冲洗机械密封后，再将压盖压紧。

Based on the analysis and comparison of published equations for vapour pressure of liquid yellow phosphorus ,a new equation has been proposed in this paper.

在分析比较文献报导的液态黄磷蒸气压方程的基础上，提出了一新的蒸气压方程；与文献数据比较，其在44～350℃下的MARE为1.58％，比现有方程的最优者低1.26％，为推算液态黄磷蒸气压提供了一种更精确的方法。

This damage criterion reflects the character of RCC, and shows that stress degree of RCC damage decreasing with heat current density vector and temperature gradient augmenting. If this process of RCC damage is in constant temperature, the damage completely depends on stress degree, which accords with the result of experiment.

结果 碾压混凝土热耗散和损伤耗散累积到一定程度时，损伤破坏就会发生，且随着热流密度矢量和温度梯度增大，碾压混凝土发生损伤破坏的应力水平将降低，如碾压混凝土是一个等温变化过程，则损伤完全取决于应力水平。

The developed piezoelectric pump can be driven directly by the utility electric power supply system and its flow rate can be adjusted by a resistor voltage divider.

所设计的压电泵可直接利用日常照明电驱动，可通过电阻分压的方法实现压电泵的流量调节。

It is obtained that the zone width of starting cut is about the first weighting step, the zone width of face is changing between 23 times of period weighting step, the zone width near intake entry and return entry is about 0.70.8 times of the first weighting step, the height of trapezoidal surface is basically subject to the location of the key strata and the deformation, breaking and instability form of the voussoir beams structure.

更多到切眼侧带宽大约为初次来压步距，工作面侧带宽在23倍周期来压步距间变化，进风巷及回风巷附近带宽约为0.70.8倍初次来压步距，内外梯台面的高度受制于关键层层位及所形成砌体梁结构的变形、破断和失稳形态。

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。
