七种不同的二元液体混合物的已发表的实验数据的分析，使我们能够测试的概念，在接口的临界现象的普遍性，并比较三个独立的通用表面振幅的值与理论预测。尽管在一个表面振幅的情况下，不舒服的大实验误差酒吧，我们发现协议为五个不同的系统和两个不一致。对于其他两个表面振幅，我们得到的理论和实验之间的边际协议，这是由于缺乏实验误差条。我们还测试了临界吸附的标度函数。鉴于数据分析的复杂性，理论和实验之间的一致性是令人满意的和令人鼓舞的。实验改进建议，以获得更严格的测试。
The analysis of published experimental data for seven different binary liquid mixtures allows us to test the concept of universality for critical phenomena at interfaces and to compare the values of three independent universal surface amplitudes with theoretical predictions. In spite of uncomfortable large experimental error bars in the case of one surface amplitude we find agreement for five different systems and disagreement for two. For the other two surface amplitudes we obtain a marginal agreement between theory and experiment which is impeded by the lack of experimental error bars. We also test the scaling functions for critical adsorption. In view of the complexity of the data analysis the agreement between theory and experiment is satisfactory and encouraging. Experimental improvements are suggested in order to obtain more stringent tests.
