除气

3 Shut off the degasser and centrifuge.

关掉除气器和离心机。

The results show that the effect of addition or no-addition of degasser on grain refinement of Al-5.0%Si alloy ingot is...

结果表明，除气剂的添加与否对Al-5%Si合金铸锭组织的细化没有影响，铸锭由粗大的柱状晶组织构成；采用合适的超声波处理时间，Al-5%Si合金铸锭的等轴晶获得率大幅度提高，可使整个铸锭组织变为细化的等轴晶组织；超声波振动时间过长将导致铸锭内气孔的增加；根据克劳修斯-克拉柏龙方程，某一强度的超声波引起的压力冲击波作用，导致液相转变为固相，引起了超声波的细晶作用。

Shut off the degasser and centrifuge.

关掉除气器和离心机。不适合

Treated and deaerated water also is pumped to the synchrometer .

经过处理和除气的水也被泵输送至同步流量计处。

The solution is degassed by alternately freezing , evacuating and thawing.

通过交替的冻结、抽空和溶化来使溶液除气。

It is shown that uniform powder cloth with proper thickness can be produced by using appropriate rolling parameters. Thermogravimetic and pyrolysis residuum analysis indicate that the burnout process of fugitive binder used to produce the cloth is found to take place in two stages, no residuum is left when degassed properly.

结果表明，采用合适的轧制参数即可容易地获得厚度合适、均匀的粉末布；热失重分析和热解残余物分析指出用来制备粉末布的有机粘结剂的去除过程分成两个阶段，合理除气后，基本没有残余物。

Under middle and high heat flux, the liquid was degassed with the result that the boiling was pure liquid nucleate pool boiling, and, hereafter, the heat transfer coefficients could not be raised with increasing dissolved gas.

实验结果发现，低热通量时，相同热通量下的壁面温度会随著可溶解气体含量的增加而降低，主要原因是增加气体含量可以降低初始沸腾的热通量；中高热通量则因液体中所含的气体被除气所致，为纯液体核沸腾，热传系数无明显的提升。

The mechanism of ultrasonic degassing was analyzed.

分析了超声波除气的原因。

The effect of the process parameters, such as the rotation speed on the degassing efficiency was calculated and analyzed.

通过计算，分析工艺参数对除气效率的影响。

This paper introduces four kinds of method for increasing devolatilizing efficiency in cold feeding vented extruder s These methods are:(1)reducing the filled degree of rubber compounds in the vented section of screw;(2)increasing the mean residence time in the vented zone;(3)enhancing the effect of renewing the evaporating surface;and (4)improving the ingredients and operating variable

介绍了 4种提高橡胶冷喂料排气挤出机除气效率的途径：减少胶料在螺杆排气段中的进料度，增加胶料在排气段中的平均停留时间，增强胶料&自由&表面积的更新作用，改进配方设计和操作工艺条件等。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
