砂子细度 meaning in English
sand fineness
Examples
- Through reiterative study over years by the author , a new principle to express the relation between aggregate particles size and the surface area was proposed , that is the specific granularity , which could solve the problem of lack of correlation of fineness modulus to the specific surface area of the sand
摘要经多年反复研究，发现了集料粒度与表面积关系法则，提出了以“比粒度”表述砂石粒度的新方法，解决了以“细度模数”表述砂子细度的不足之处，即解决了细度模数与不同细度砂子的比表面积没有相关性的问题。
