摘　　要：文章运用低频表面波衍射法,搭建系统装置来研究低频液体表面波的特性。通过对低频液体表面波光衍射的分析,得到衍射光场的分布和表面波之间的解析关系。根据这一关系,可以测量出液体表面张力。与传统液体表面张力测量方法相比,本实验测量法具有简便、无损、智能化特点,并有很高的测量精度和可操作性。In this paper, the low frequency surface wave diffraction method is used to study the characteristics of low frequency liquid surface wave. By analyzing the diffraction of wave light on the surface of low frequency liquid, the analytical relationship between the distribution of diffraction light field and the surface wave is obtained. According to this relationship, the surface tension of liquid can be measured. Compared with the traditional liquid surface tension measurement method, the experimental method is simple,non-destructive, intelligent, and has high measurement accuracy and maneuverability.
