查询词典 brightnesses

An increase of 1 in magnitude corresponds to a decrease in brightness by a factor of 100^(1/5)= 2.51188... Using this scale, it was found that the stars traditionally placed in the same category sometimes had brightnesses that fall outside the numerical bounds for that category.

增量1在巨大对应于在亮光的a减退由因素100^ (1/5)= 2.51188… Using这个标度，发现星传统上安置了 in同一个类别有时有在之外下跌的亮光那个类别的the数字区域。
