Coarse aggregate size distribution is important for the research on concrete strength analysis. Usually it can not be obtained without cutting a part of concrete down.
粗骨料粒径分布对混凝土强度分析有重要影响，但如果不用切割方法，混凝土内粗骨料三维粒径分布测量就无法实现。
It is also shown that linear swelling and size distribution experiments have good identity; that is, the stronger the inhibition is, the easier it is to make montmorillonite particles aggregate.
结果还表明，线性膨胀实验和粒度分布实验具有同一性：即抑制性越强，越容易使蒙脱土颗粒聚集。
