| 摘 要： | 为了进一步探讨影响液体表面张力系数的主要因素，研究了低频液体表面张力系数在不同温度下的变化特性，用激光来照射液体表面，利用其形成的衍射图样与表面波参数之间的关系，计算出了在不同温度下的纯净水表面张力与温度之间的关系。实验结果表明纯净水表面张力随温度增长近似成线性递减的关系。本方法具有实时、非接触的特点。

| Abstract: | In order to further investigate the major factors of affecting the liquid surface tension , this article explores the relationship between the liquid surface tension of pure water and the temperatures by using the relationship between the diffraction patterns formed by the irradiation of laser to the liquid surface and the parameters of the SAW. The results show that the coefficient of surface tension of pure water is related to the temperature. This technique is characterized by real time and non- contact. |
