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。

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。
