| 摘 要： | 通过用毛细管测量纯水表面张力系数实验，得到管内径d与接触角θ的相对误差之间的关系曲线，由此说明实验测得的表面张力系数α和理论公式相比呈现一定的偏差，并简单地讨论了实验的理想状态与实际情况的差别．

| Abstract: | The relationship currve between the inside diameter of capillary tube and the relative error of contact angle can be obtained in the experiment of measuring the surface tension coefficient with capillary tube. The surface tension coefficient measured in the experiment appears some errors compared with theoretical formula. The difference between the ideal condition and real condition in the experiment is discussed. |
