装填器

Simulation results of gas membrane separation operating in countercurrent show good agreements with experimental results.

中空纤维式分离器因其装填密度大、耐压性能好，因而在实际的气体分离过程得到广泛的应用。

Derived from the 1929 fortress gun (itself a development of the old 1897 field gun) with a semi-automatic breech and an automatic loader added, the "high power" APX 75mm gun fired a mle 1915 HE round with a reduced charge at 400 m/s and the mle 1915 AP round at 570 m/s (50mm penetration at 1000 m) and its two sights and stereoscopic rangefinder allowed a direct fire range of 2000 m.

&大威力&APX型75毫米炮由1929型要塞炮（旧式1897型野炮的发展型）衍生而来，加装了半自动炮尾和一个自动装填器，发射减装药的1915型高爆弹（初速400米/秒），及1915型穿甲弹（初速570米/秒，1000米距离可穿透50毫米装甲）。

Experimental date of extraction in different packing fraction module were verified. The mathematic model established in this paper can predict shellside mass transfer in hollow fiber reflecting module precisely.

由不同装填系数膜器的萃取实验数据对模型进行了验证，结果表明，本文建立的数学模型能较好地预测折流膜器的壳程传质系数。

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%.
