One reason is that the electrical resistance in the corona is typically quite low - too low to account for the explosive rate at which solar flares brighten.

一个理由是日冕中的电阻一般说来是相当低的，低到不足以解释日焰爆发时增亮的程度。

The nano-alumina dispersion solution can then be mixed with an imide coating to provide for a wire coating to give the wire improved abrasion, COF, and corona resistance.

纳米氧化铝分散体溶液可与酰亚胺涂料 混合，提供漆包线漆涂层，得到耐磨性、COF和耐电晕性得到改进的线 材。
