Results show that the frequency spectrum characteristics of arc diffluence is accordance to jet fluctuation. Arc diffluence in the new gun is confined obviously.

试验结果表明，电弧分流和射流脉动的频谱特性是一致的，在使用新等离子体喷枪时，电弧分流明显得到了限制。

If you want to a more forceful, stiffer arc, you can tighten the frequency.

如果你想要一个更有力、更严厉的弧形，可以加强频率。

Anthem's true audiophile approach with ARC instead uses proprietary processing to compute each speaker's in-room frequency response and then computes a target frequency response for each to yield the optimal sound.
