The correlation between mass density and refractive index is analysed on the basis of a model comprising compact grains (i. e., amorphous or crystalline) and pores filled with air or water.
建立了由微小颗粒(无定形的或结晶的)和填充空气或水的小孔构成的模型，在此基础上分析了质量密度与折射率的相关性。
Based on experimental apparatus, how the spray density and water temperature affected the heat and mass transfer performance of the evaporative condenser are studied.
在蒸发式冷凝器性能测试实验平台基础上，测试了水流参数如喷淋密度和水温对蒸发式冷凝器传热传质性能的影响。
The effect of the rise of ground water level was simulated by increasing the mass density of pore water in the soil elements between the initial and targeted ground water levels.
通过逐步改变初始和终止地下水位间土单元中孔隙水的密度模拟地下水位上升的效应。
Effects of bulk density on the two parameters were analyzed. The results showed that saturated mass water content decreased with the increment of bulk density and was inverse to bulk density.
结果表明：饱和重量含水量随容重的增加而减小，与容重成反比关系，饱和导水率随着容重的增加呈现幂函数形式递减。
