difference of densities meaning in Chinese
上下密度差
Examples
- Difference of densities
上下密度差 - Because of the difference of density , the particle with big conductivity factor will subside in the organic phase change materials , so the orginic phase change materials were solided . the best technology was determined , which the solidation fatty alcohol was made by two steps , the solidation temperature is at 80 , and the proportion of fatty alcohol : fatty acid : sodium hydroxide is 96 : 3 : 1
由于密度差的存在，高导热系数粒子在有机相变贮能材料中会产生沉降，为了克服这一现象，对有机相变贮能材料进行了固化研究，确定了制备固化十二醇的最佳工艺条件，即采取两步法、固化温度为80 、添加比例为十二醇：硬脂酸：氢氧化钠= 96 ： 3 ： 1 (质量比) 。 - The experiments reveals that : the amount of water vapor transfer is affected by both water content gradient and the value of water contents , when the water content of one end is approximate , the water content gradient increases , then the amount of water vapor transfer increases ; when the water content gradients are approximate , the amounts of water vapor transfer can get great differences if the water contents are different , under this condition when the water content of the dry soil is very little , the amount of water vapor transfer is much greater ; the differences of density hav n ' t great effects on water vapor transfer , but have some effects on the admixture transfer , when the density is smaller , the amount of admixture transfer is greater . the water vapor transfer finishes more quickly and need less time , and the liquid water finishes more slowly and need less time
当一端含水量一定时，增加含水量梯度，则气态水迁移量增大；当含水量梯度相近时，气态水迁移量随含水量不同可能相差很大，这种情况下当较干段含水量特别小时，气态水迁移量相对较大；密实度的大小对于气态水迁移的影响并不明显，但对液态水和气态水的混合迁移有一定的影响，在相同的实验时间内，土体密实度较小，则混合迁移量相对较大；气态水迁移完成速度较快，所需时间较短；液态水迁移完成速度较慢，所需时间较长。
