英语翻译
（1）水模拟：是在水中加入特殊溶液使其粘度与铝液大致相仿.主要考量在不同转数、不同气量、不同浸入深度时的气泡大小及分布情况来制定实际的设备参数并在使用中进行微调,使之达到最佳效果.
（2）除气设备动态模拟：考量转子转速对液面的影响,对液面氧化浮渣的影响、气泡在动态不规则腔体中的分布情况.溶液中气泡合泡情况等.
（3）微气泡浮选床：采用脉冲供气,脉动气压供气,脉动气量三种工期方式进行比对和基气来确定最佳供气方式,达到浮选床的形成.
（4）随着叶轮的旋转,铝水跟着带动而形成漩涡,高温铝液表面氧化膜遭破坏,造成夹杂和吸气,严重影响除气效率.防漩涡带翼翅叶轮的设计,可以有效防止这一点的产生.叶轮叶片采用一斜一平设计,侧面开多个微孔,经叶片重复剪切使气泡微小弥散.
（5）内腔多面体，底部小，上部大呈喇叭状。使较小的叶轮剪切的气泡能够完全覆盖除气腔底部，并由下至上成喇叭状扩展防止合泡得产生。
（6）设备密封性极好在除气过程中随着惰性气体的逸出会充满整个腔室实现惰性气体保护下进行除气，氧化浮渣极少，但随着逸出铝液面的惰性气体增多，气压加大，会影响除气效率，故在上盖设置随气压波动的平衡装置--排气孔，该排气孔也是排灰孔。

(1) the water simulation:special solution is added to the water so that the viscosity and liquid aluminum similar.Equipment parameters of main consideration of bubble size and distribution in different speed,different content,different depth of immersion time to formulate practical and fine-tuning in use,so as to achieve the best effect.
(2) except the dynamic gas equipment simulation:considering the effect on rotor speed on the level,distribution,influence on surface oxidation scum bubble in dynamic irregular cavity in the.Solution bubble bubble.
(3) micro bubble flotation bed:the pulsed gas,pulsating pressure supply,pulse volume three period for comparison and based gas to determine the optimal supply mode,formed to a flotation bed.
(4) with the impeller rotation,aluminum water followed to form a vortex,the oxide film on the surface of aluminum liquid destruction,caused by inclusions and inspiratory,serious impact on the degassing efficiency.Design of anti swirl impeller with wings,can effectively prevent this point.A design of the impeller blade inclined and flat,side open multiple micropores,the blade repeated shear the bubble micro dispersion.
再问： 还要麻烦大大帮忙翻译一句
（5）氩气或氮气经过石墨转子与铝液的相对高速剪切，产生细小的气泡并均匀分布在铝熔体中。由于气泡中氢分压为零，铝熔体中的氢分压高，铝液中的氢渐渐向气泡中扩散。同时，铝液中的金属及非金属夹杂物被吸附在气泡的表面，随气泡一起上浮，从而达到去除铝液中氢及夹杂物的目的。
再答： (5) argon or nitrogen through a relatively high shear rotor graphite and aluminum liquid, to produce fine bubbles and uniform distribution in aluminum melt. Due to the bubble of hydrogen partial pressure is zero, the partial pressure of hydrogen in aluminum melt, aluminum liquid hydrogen diffusion in the bubble gradually to. At the same time, metal and non-metallic inclusions in liquid aluminum is adsorbed on the surface of bubbles, floating with the bubble, so as to achieve the removal of hydrogen and inclusions in liquid aluminum purpose.
