摘　　要：通过用动态法研究浸润粉层的液体重量随时间的变化规律，测定了甲、乙、丙、丁、戊醇对SiO2粉末层的平均毛细管半径、弯曲率、接触角及浸湿功.结果表明，醇对SiO2粉层的毛细管平均半径随碳氢链的增长而增加，除甲醇外.前进接触角亦随之增加.Through dynamic method to determine the weights of some liquids varied with time while metting the silicon dioxide powder, the contact angles, bending ratio, average capillary radius and wetting work are calculated, such as methanol, ethanol, propanol, butanol and pentanol. The result is that the average capillary radius increases with the length of carbohydrate,and the contact angle is the same except methanol.
