A comparative study of the temperature dependence of the elastic constants of the nematic liquid crystals known as PAA (p-azoxyanisole), MBBA 4'-methoxybenzylidene-4-n-butylaniline, and 5CB (4-n-pentyl-4'-cyanobiphenyl) will be made in this work. After a regularization of their values, and with use of a unique temperature scale, the experimental data of each of these parameters will be displayed along the lines of corresponding states that are not restricted to the neighborhoods of the nematic-isotropic phase transition point, as it would be the case in a usual corresponding states law, but encompass the entire nematic phase.
在本研究中，将对被称为PAA（对甲氧基偶氮苯甲醚）、MBBA（4'-甲氧基苄叉-4-正丁基苯胺）和5CB（4-正戊基-4'-氰基联苯）的向列型液晶弹性常数的温度依赖性进行比较研究。在对其数值进行正则化处理后，并使用唯一的温度标度，这些参数中每一个的实验数据将沿着对应态的线展示出来，这些对应态并不局限于向列-各向同性相变点的邻域，而不像通常的对应态定律那样，而是涵盖整个向列相。
