1. Except for v, the exponents in these power laws are related to one another because they all result from differentiating the universal function go (in Eq. [4]) with respect to Tand/or h and then evaluating the results at particular values of z. Typical relations among the exponents are a = 2 - ft(6+1) * 0.11 and 1 = £(.6-1) « 1.24, where the numbers quoted are appropriate for the d = 3, n = 1 class. In contrast to tests of scaling, the experimental study of power laws requires data along a single path through the critical point; thus, the measurement of critical exponents has received much more attention than tests of scaling.
