| 摘 要： | 介绍了液饼高度法测定铺展系数的基本原理，测定了一些液体在石蜡和明胶薄膜上的铺展系数，结果表明，由铺展系数计算出的接触角与实测值相等，表面活性剂可改进润湿性质。

| Abstract: | The basic principle of measuring spreading coefficients by the large sessile drop method has been introduced.The spreading coefficients of some liquids on the paraffin and gelatin film were measured.The results show that the contact angles calculated from spreading coefficients are equal to the measured volues.The surfactants often can improve the wetting behavior. |

| Keywords: | wetting spreading coefficient large sessile drop method contact angle |
