摘要：

Recently, Bhargava and Kumar studied the random bond and the random site problem for a Heinsenberg model. They calculated the critical temperature Tc as a function of the bond or site concentration x using a two-spin cluster expansion. In contrast to their paper it can be shown that Tc(x) is the same in both cases. © 1979 The American Physical Society.
