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，高導(dǎo)熱系數(shù)粒子在有機(jī)相變貯能材料中會(huì)產(chǎn)生沉降，為了克服這一現(xiàn)象，對(duì)有機(jī)相變貯能材料進(jìn)行了固化研究，確定了制備固化十二醇的最佳工藝條件，即采取兩步法、固化溫度為80 、添加比例為十二醇：硬脂酸：氫氧化鈉= 96 ： 3 ： 1 (質(zhì)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
當(dāng)一端含水量一定時(shí)，增加含水量梯度，則氣態(tài)水遷移量增大；當(dāng)含水量梯度相近時(shí)，氣態(tài)水遷移量隨含水量不同可能相差很大，這種情況下當(dāng)較干段含水量特別小時(shí)，氣態(tài)水遷移量相對(duì)較大；密實(shí)度的大小對(duì)于氣態(tài)水遷移的影響并不明顯，但對(duì)液態(tài)水和氣態(tài)水的混合遷移有一定的影響，在相同的實(shí)驗(yàn)時(shí)間內(nèi)，土體密實(shí)度較小，則混合遷移量相對(duì)較大；氣態(tài)水遷移完成速度較快，所需時(shí)間較短；液態(tài)水遷移完成速度較慢，所需時(shí)間較長。
