介绍了用手工电弧堆焊的方法将一些空气锤零件修复的实例，对延长空气锤零件的使用寿命、约生产成本有一定的参考价值。

The intermittent alternative transverse magnetic field has influence on the swing frequency of welding arc.

外加横向间歇交变磁场改变了电弧的摆动频率。

It has a good ability of antipollution and water proof.

具有防水耐电弧、耐紫外线、耐老化和寿命长等特点。

The aim of the STEEL REFINING SYSTEM is to remove oxygen, sulphur, carbon, slag from molten steel and sharply matching molten steel component by arc heating and blowing inert gases.

设立该项目的目的是将装有初炼钢液的钢包边电弧加热边底吹惰性气体，进行脱氧、脱硫、深脱碳、去除夹杂及成分微调等。

It is the first time that no additional anode was adopted in the magnetic macroparticles filter. At the same time the auto-re-igniting system was designed for vacuum cathodic arc deposition instrument. It ignites the arc with an electronic component with high voltage and can auto distinguish weather the arc dies out or is on during the deposition via a main power supply feedback unit. The energy for igniting the arc is very less and thus can successfully prevent the film being contaminated.

设计制造的电子式真空阴极弧离子镀引弧器成功地实现了高压脉冲引弧，可以多次重复使用，所用能量较小，可以有效防止对所镀膜的污染，引弧可靠，能够自动识别电弧是否引燃，能够在熄弧后自动重新引弧，重新引弧的速度快，有效防止了熄弧引起的气压波动，使镀膜过程中气压非常稳定。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
