The research results show that the incipient motion and the erosion of cohesive deposits are greatly influenced by the dry bulk density.

研究结果表明：干容重对粘性淤积物起动和冲刷的影响非常大。

As increasing saturation degree and decreasing dry bulk density, the dilatation disappears. The destructional forms of samples may be influenced by dilatation.

在三轴不排气剪切过程中，试样出现了明显了的剪胀性，且随着干密度的减小，饱和度的增大剪胀性逐渐消失。

The only input factors of the simplified model were soil radium content, dry bulk density, water content and soil texture type and the output was soil radon exhalation rate.

模型只需输入土壤样品镭含量、容重、质量含水率和质地名称，就可以输出该样品的氡析出率理论值。
