| 摘 要： | 酸性粒子在许多环境问题中起着重要的作用.它们的大小一直用Gras公式计算.但在实际的研究中发现Gras公式有时并不合理.提出对Gras公式进行改进以粒子投影长度L与截面积直径d的比例关系,L/d<0.62用Gras公式计算,0.62～1.62用修正的Gras公式计算,＞1.62须具体对待.并用具体算例证实了新算法的合理性.

| Abstract: | Acidic particles are important lots of environmental problems. Their size used to be calculated are using Gras formula. But Gras formula has been found unresonable sometimes during studying, and then modification was proposed: Taking precise projected-length and proportional relation with cross-section diameter d, L/d: when <0.62 should be calculated with Gras formula, and L/d <0.62 - 1.62 it should be calculated with modified Gras formula, it should be treated concretely when >1.62, and using certain actual case to prove that the calculation method was reasonable. |
