解吸因数的大小排列顺序为：黄红壤、粉泥土、高岭土、珍珠岩、青紫泥、硅藻土。
The order of Df (desorption factor) value was: yellowish red soil>silt-loamy soil>kaoline>perlite>paddy soil (loamy clay) >kieselguhr.
实验中研究了硅藻土与熔块釉粉之比对试样的吸、放水率，吸、放湿气率等的影响；并且探讨了改性剂、成型压力以及保温时间对吸、放水率等的影响。
The effects on water-absorption and water-desorption of the mixture ratio of diatomite powder and frit particles as well as modifiers, forming pressure and soaking time were studied.
结果表明，硅藻土加入量增加后，传输曲线的峰值下降，时间缩短。而云母粉则与之相反。
The results showed that the peak value and time in the transfer curve decrease with the increase of the diatomite addition while the result is just contrary to the increase of mica powder addition.
