The design of the gun is commonly defined by perveance, beam current, waist radius, waist position and cathode current density.

它的设计主要有导流系数、流、腰半径、腰位置以及阴极电流密度。

The distribution ratio of silver in aftonite and pyrite is the most important factor to determine granularity, current density and electrolytic time.

银在银黝铜矿和在难分解的黄铁矿中的分配率是决定矿粉磨细粒径、电解面积电流、电解时间的最重要因素。

To realize the high efficiency of dernisting, thenew type cathode wires and anode tubes with superperformance were developed for increasing the current density and field intensity.

实现除雾高效化，关键在于研制高性能的新型阴极线和阳极管，提高电流密度和电场强度。

The arc pressure distribution is in concordance with the hyperbolical curve and the current density distribution is in concordance with the Guass distribution under the presented experiment condition.

实验结果表明，在本试验条件下，电弧压力分布符合双面指数曲线分布，电流密度分布符合高斯分布规律。
