摘　　要：基于拉脱法测量液体表面张力系数的原理,采用排水法和杠杆原理来测量水的表面张力系数,实验结果表明,使用该文装置测量的结果与标准值符合得很好,与传统的拉脱法相比,测量精度有了很大的提高。该方法具有实验仪器简单、可操作性强、实验结果精确等优点,能够为测量液体表面张力系数提供一种新的途径。This experiment method is based on the principle of measuring liquid surface tension coefficient using the pull - out method. We measured the water surface tension coefficient by firstly using drainage method and lever principle electronic balance. The experiment results show that the experiment results measured using our experimental device are well agreement with the standard result. Compared with the traditional drainage method, measuring precision is improved largely. Our method has the advantages of simple ex- perimental apparatus, strong operability and accurate experimental results and so on, which can be provide a new way to measure liq- uid surface tension coefficient.
