number density 释义 数密度:单位体积内的粒子数。 例句 1·The electron number density does not strictly obey exponential damping law in a long period. 电子数密度在很长的一段时间内不遵循指数衰减规律。 2·The inclusion number density and concentration have the similar distribution in the RH degasser. 夹杂物浓度和数量密度具有相似的空间分布; 3·Finally, the influence of shear rate and the number density and aspect ratio of the fibers are discussed. 最后讨论了纤维的浓度和长径比等因素对悬浮流微观和宏观性质的影响。
