compactability

The organic litter will help to cushion trampling forces, limit the compactability of soils, release plant nutrients, and reduce the erosie forces of rainfall.

这些杂物有助于缓冲踩踏地面力量,避免土壤结块成形,释放植物营养物,而且减少降雨。

The measuring method of sand compactability in laboratory is analyzed,and a fast measuring method is designed,and the intelligent instrument for fast measuring sand compactability are developed.

分析了铸造行业型砂紧实现有测试方法,提出了机电型砂紧实快速智能测试方法,并据此研制成功了便携式型砂紧实快速智能测试仪。
