测量了表征二氧化碳和氙气粘度差异的临界指数 y。两种流体的 y 值均落在 y = 0.041 + 或 - 0.001 范围内，并且与四种二元液体混合物的早期数据所跨越的范围 y = 0.042 + 或 - 0.002 一致。这一一致性是纯流体和二元液体处于同一动态普遍性类别的最有力证据；然而，y 的结果与最近的理论值 0.032 不一致。
The critical exponent y characterizing the divergence of the viscosity for carbon dioxide and xenon has been measured. The values of y for both fluids fall within the range y = 0.041 + or - 0.001 and are consistent with the range y = 0.042 + or - 0.002 spanned by earlier data for four binary liquid mixtures. This agreement is the strongest evidence that pure fluids and binary liquids are in the same dynamic universality class; however, the results for y are inconsistent with the recent theoretical value of 0.032.
