The intermittent pulse signal with frequency 20khz is generated by embedded software and then amplified by external power driving and voltage transforming circuit. the output -6kv high voltage is applied to the front end of the carbon fiber brush and negative ions are generated when air goes through the brush.
利用单片机软件产生20khz间歇性脉冲信号，通过功放、升压、整流变换，输出-6kv左右的高压，加到碳纤维电极上，由空气电离效应产生所需的负离子。
With his brush, the boxy roofs became puzzle pieces, the arches of the local viaduct a study in the contrast between positive and negative space.
在他的画笔下，四方的屋顶都变成了拼图的碎片，在正副两种空间的对照之下，当地高架桥的拱门成为独特的杰作。
The negative carbon brush damage often occurs in operation.
运行中负极电刷易受损伤。
In Haiwang's recent works, both human and still life or landscape, and attempt to change the subject and content. This may reflect his mood changes perspective, but the picture has not changed is its inherent passion obviously, The core of Haiwang's oil painting is a painting scraper and brush movement, in any of his works, fierce campaign after the knife left at the scene, as the master of painting, The result is a kind of aggressive and negative values, which led to some kind of freedom. no logic chance effect.
海旺近些年的作品，无论是人体，静物，还是风景，内容与题材的变化与尝试，或许能够体现其心境的变化，视角的转移，但画面中不变的是其内在激情的显现，很显然，海旺的绘画核心在于油画刀笔的运动，在任何一张他的作品里，激烈的刀笔运动之后留下的痕迹，成为油画的主宰，以至于具有了某种侵略性和否定性的价值，进而导致某种自由的、非逻辑的偶然性的效果。
The results showed that, during electrical wear process, the contact voltage drop of both positive and negative brushes had the same trend: be stable after first increase, and the contact voltage of negative brush was always bigger than positive brush.
研究发现，在电磨损过程中，正负电刷接触电压降变化趋势相同&先上升然后趋于稳定，且负刷的接触电压降大于正刷的接触电压降。
When a flexible negative plate electrode cyclically moves, deposited dust on the plate electrode can be automatically cleaned by a double-face brush.
柔性负电板极在循环运动时，被双面刷子自动清洗板极上的集尘。
Dragon Boat Festival every year before, my mother would buy a lot of the street? , both positive and negative to go home after a clean brush, and then a bowl of rice Amoy, moving two, and the father with dumplings package.
每年的端午节前，妈妈都会到街上买回大把的粽叶，回家后将正反两面刷得干干净净，然后淘一盆糯米，搬两个小凳，和老爸一起包粽子。
The result shows that the nano-particle surface charge is negative and its diameter distribution is more wide in brush plating solution.
实验结果表明纳米颗粒在镀液中荷负电，其粒径分布较广；
This was because the water entrapped in the lubricating film was ionized in the presence of the electric current to generate highly active negative oxygen ions, which led to the oxidation of the positive brush and accelerated its wear.
其原因在于，摩擦副接触表面润滑膜中的水在电场作用下发生离解，在正刷侧释放出活性氧，活性氧与电刷表层中的碳或金属发生氧化反应，从而使得磨损加剧。
