电弧

One bituminous coal was gasified in steam medium with air as carrier gas under plasma conditions.

以水蒸气为气化介质、空气为输送介质，对煤在电弧等离子体中的气化行为进行了研究；所用等离子体反应器由石墨管阳极和石墨棒阴极构成；反应器内的等离子体通过外置线圈产生的磁场进行约束和控制。

Then the arc was ignited and the current was maintained at 80 A for 5 hours.

然后电弧被点燃，以及目前维持在80 5小时。

Adjacent switchgears are isolated by its self side board, afterputting the switchgears together, air buffer layer exist yet, it may prevent the switchgears from pronging and melted by electric arc.

相邻的开关柜由各自的侧板隔开，拼柜后仍有空气缓冲层，可以防止开关柜被故障电弧贯穿熔化。

An arc due to an AC signal usually quenches itself as soon as the voltage level passes through zero.

交流信号产生的电弧通常在电压通过零点时就会自己熄灭。

Several theories about reigniting and extinguishing of the arc have been refered.

本文综合考虑了几种电弧重燃和熄灭理论。

The computed result indicated that the overvoltage of no-fault phase was determined by the instant voltage, when there is reigniting of fault phase.

仿真结果表明，健全相的过电压值取决于故障相电压发生重燃时刻的瞬间电压值，重燃击穿电压越大，一定时间内电弧重燃的次数越少。

The number of restrikes can be decreased significantly by using a bipolar load current arc conditioning.

只有通过两个极性负载电流的电弧老炼才能有效地减少真空开关的弧后延时重击穿现象。

By discussing the influences of restriking phenomena, some effective methods are presented for restraining restriking phenomena and improving the performance of current limiting.

通过分析影响开断过程电弧重击穿现象的主、要因素，本文提出了几种抑制开断过程重击穿现象、提高断路器限流特性的有效方法。

Surface roughening is very important in arc spraying, as the coating quality depends greatly on its treatment result.

表面粗化在电弧喷涂中具有重要作用，涂层质量很大程度上取决于表面粗化预处理的效果。

The major reaction product of coal in the arc plasma reaction is acetylene and CO. The acetylene is come from the saturates and aromatics in the coal.

2煤在电弧等离子体中反应的主要的产物是乙炔和一氧化碳，乙炔的来源主要是煤中的饱和分和芳香分。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
