Harkins-Jordan 校正因子使环法成为测量表面和界面张力的精确且绝对的方法，该校正因子经过理论计算并以表格形式提供。数值表的适用范围远远超出了文献中通过实验获得的范围。通过制表，环法可用于测量界面上密度差很小而界面张力较大或密度差较大而张力较小的液体体系的界面张力。理论计算还提供了有关液体界面处的环状态的信息，这可用于提高环法的准确性。
TheHarkins-Jordancorrection factors which make the ring method an accurate and absolute method of measuring surface and interfacial tensions, are calcuated theoretically and made available in a tabulated form. The applicable range of the numerical tabulation far exceeds the range of those available in the literature which have been obtained experimentally. With the tabulation, the ring method may be used to measure the interfacial tensions of liquid systems in which the density difference across the interface is very small and the interfacial tension is large, or in which the density difference is large and the tension is small. The theoretical calculations also provide information on the state of the ring at the liquid interface which may be used to increase accuracy of the ring method.
