| 摘 要： | 采用透气法，量测了细颗粒泥沙的比表面积．发现泥沙的实际比表面积远大于其等容球态粒子的比表面积．通过资料分析，建立了粒子的相对比表面积与平均粒径及其轴比之间的函数关系．从而为实际应用提供了方便

| Abstract: | In this paper,air permeability test has been conducted to determine the specific surface area of fine particle of sediment.It was uncovered that the specific surface area of sediment is bigger than that of spheric particle of the same diameter.Furthermore,the functional relationship among the specific surface area,the average diameter and the proportionality of axis has been established for actual use. |
