气

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。

Results: of 135 cases, reduction a shot 75 patients (55.5%),reduction again after intermittent insufflation , massage with hands or intramuscular injection with 654-2 48 patients (35.5%), failure reduction 12 patients(9%).

A mathemetical model of magnetic field in electromagnetic separation of inclusions from molten aluminum under rectangle coil and 50Hz current is presented according to the magnetic vector potential integral equation and the basic theory of magnetohydrodynamics. The magnetic field distribution in the gap of coils is simulated by the model and the actual magnetic field distribution also is measured. The experimental results show that the magnetic field distribution in the gap of coils is uniform and is consistemt with the model simulation. The magnetic field designed accord the simulated result is proved suitable in the practice.

摘 要：根据电磁流体力学的基本理论，利用矢量磁位积分，建立了在采用矩形电磁线圈和工频电源的条件下电磁分离铝熔体中夹杂的电磁场数学模型，模拟计算了电磁感应线圈气隙中的磁场分布状态，同时对制做的感应线圈的实际磁场进行了测量模拟计算磁场的分布状态与实际磁场的测量结果基本一致，都表明在电磁感应线圈气隙中磁场分布均匀，可以进行分离铝熔体中的非金属夹杂。

Meanwhile, we explored discharge characteristics and influence factors (interelectrode distance, temperature, atmospheric pressure, relative humidity, etc) through experiments. To optimize the characteristics of ionization sensor, we studied the diameter, distance and height of carbon nanotubes when field effects of carbon nanotubes were in optimized conditions.

Consider to think, although apparent gaseous state is not had in 0 derv of the interfuse in artesian well fluid,hydrocarbon exists, but fall in certain environmental temperature condition, the volatilization with have certain free hydrocarbon composition appears C_(11 the following liquid state volatilizes hydrocarbon , what cause gas to measure complete hydrocarbon thereby is unusual, but the change that this won't cause gas to measure constituent to be worth however, use this one characteristic, can lift with complete hydrocarbon and the method with not elevatory firedamp will distinguish the complete hydrocarbon holiday that mixes fluid of derv artesian well to cause is unusual.

探究认为，虽然钻井液中混入的零号柴油中并无明显的气态烃存在，但在一定的环境温度条件下，将有一定的挥发游离烃成分出现C_(11以后的液态挥发烃，从而引起气测全烃的异常，但这却不会引起气测组分值的变化，利用这一特征，就可以用全烃升高而甲烷不升高的办法来区分混柴油钻井液引起的全烃假异常。

But I come to be an interviewee.' Jack was short of breath.

我是来面试的，'杰克上气不接下气地说。
