摘　　要：介绍了液滴形状法测量单根纤维接触角的基本原理 ,利用显微镜观察液滴的形状 ,将数据输入根据Young Laplace方程编写的程序中计算出接触角。通过实验验证 ,该法简单可行 ,可以有效的表征 0～ 60°的纤维表面接触角。The fundamental of droplet profile method for the determination of contact angle between liquid and monofilament was introduced. Contact angle can be calculated by inputting the data of liquid droplet profile measured with a microscope into a program based on Young-Laplace equation . The experimental results proved that the method was a convenient,feasible and efficient way to characterize contact angle in the range of 0-60°.
