电离电流

The influence rule to powder quality and quantity from some technical parameters such as materials vapor tension, gas pressure, the ratio between hydrogen and argon, current intensity and gas circulate intensity were discussed by single-factor experiment, on the base of which the perpendicularity experiment scheme was arranged.

本文采用压力模型计算出稳定弧光制粉时的气相空间温度在373K以下；从电流密度和电导率角度计算出等离子体电弧场中心温度高达5000-6500K；由此得出弱电离等离子体自由弧的自身温度场即使没有外界强制冷却，在等离子体焰区特征半径(约1.26cm)范围内的温度梯度就可达4787℃/cm，这是电弧等离子体温度场分布高度集中的具体表现，也是纳米金属粉末无须液氮冷却就能生成的本质原因，阐释了等离子体温度场自身的极大温度梯度是金属粉体纳米化的控制机制。

The technique problems such as quick charging of high voltage capacitor, uniform discharge in high pressure large aperture zone, uniform flow of high pressure gas, and laser resonator, high energy pulse output and high repetition pulse output, were solved by applications of ultraviolet preionization, two-circuit series and parallel discharge structure of graphite Ernst electrode, folded resonator that embodies super-thin water-cooled non-deforming mirror, closed circle direct cooling system of double loop and high-voltage high-current switch power supply.

Different from cold cathode glow discharge, the avalanche process is not only determined by electron collision induced ionization, the deionization process also plays a decisive role due to the high electron and ion density under high gas pressure and large discharge current.

与常规辉光放电不同的是，阴极区中的巨浪增益不仅仅是由电子碰撞电离过程决定的，而且由于高压强、大电流条件下电子和离子的浓度高，电子空间复合过程也起着决定性作用。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
