1·Low grain weight and bulk density.

容重、千粒重较低。

2·If the sample is weighed, its bulk density can also be calculated.

如果把样品称重，还可以确定样品的体积密度。

3·Further to this, permeability is worsened, and bulk density decreased.

从而造成透气性差、密度与比重降低。

4·Its bulk density than plank light, good recovery, cheap price, construction is convenient.

其容重比板材轻，有良好的回弹性，价格便宜，施工方便。

5·So the effect of plant roots should be considered in the calculation of soil bulk density.

在土壤容重计算过程中，应考虑植物根系的作用。

6·The effects of different temperatures on compressive strength and bulk density were studied.

主要探讨了不同的烧结温度对试样的耐压强度和体积密度的影响。

7·The porosity, bulk density and cold crushing strength of the refractory samples were determined.

讨论了气孔率、体积密度和常温耐压强度与电熔氧化镁加入量之间的关系。

8·The PCE saturation in clay sandy was higher than that in the clay loam at the same bulk density.

比较两种质地土壤，在相同容重下在砂壤中PCE的饱和度较重壤土中的大。

9·The indexes are the wood property and character, namely, DBH, bulk density, fiber length, MOR etc.

调查项目为胸径及容积密度、纤维长、弹性模量等材性性状。

10·An amende nt should decrease bulk density increase toltal porosity and incr ease water and air content.

改良剂能降低容重，增加总孔隙度，增加水和空气的含量。
