When when Ar gas is wrapped by insufflate steel, bubble generates inside steel fluid, ascendant bleb is pounded by fits and break through broken bits layer,; of generation slag blister at the same time, broken bits layer produces wave motion, fluctuant frequency increases as the addition of Ar throughput.

当Ar气被吹进钢包时，在钢液内产生气泡，上升的气泡间歇地冲击并突破渣层，产生渣眼；同时，渣层发生波动，波动频率随着Ar气流量的增加而增加。

The invention relates to a method for treating gaseous VOCs by a solid extraction-electro-catalytic oxidation method and a device thereof. The method has the steps that: firstly, an electromagnetic type air compressor is used for controlling the gas flowing velocity by a glass rotameter so as to ensure contaminations in the contamination solution in a gas washing bottle to be stripped into an electrochemical reactor; secondly, microporous aeration heads are distributed in the electrochemical reactor, after being stripped into the electrochemical reactor, the gas is distributed in the electrochemical reactor by the microporous aeration heads, takes parts in the electrochemical reaction and passes through the cathode of absorptive and conductive porous material and the anode of iron sheet in sequence; thirdly, the treated gas finally flows out from the top end of the electrochemical reactor and enters into the gas absorption solution.

As the smoke that goes up into heaven from some city that is being beleaguered on an island far out at sea- all day long do men sally from the city and fight their hardest, and at the going down of the sun the line of beacon-fires blazes forth, flaring high for those that dwell near them to behold, if so be that they may come with their ships and succour them- even so did the light flare from the head of Achilles, as he stood by the trench, going beyond the wall- but he aid not join the Achaeans for he heeded the charge which his mother laid upon him.

仿佛烟火腾升，冲指气空，远处海岛上的一座城堡，受到敌人的围攻，护城的人们在墙上奋勇抵抗，苦战终日，及至太阳西沉，点起一堆堆报警的柴火，呼呼地升腾，告急于邻近岛屿上的人们，企盼他们的营救，驾着海船赶来，打退进攻的敌人――就像这样，阿基琉斯头上烈焰熊熊，冲指明亮的气空。他从墙边大步扑进，站在壕沟边沿，牢记母亲的命嘱，不曾介入阿开亚人的营伍。
