摘要：

We show how the critical point and the ratio gamma/nu of critical exponents of the finite temperature deconfinement transition of SU(2) gauge theory may be determined simply from the expectation value of the square of the Polyakov loop. In a similar way we estimate the ratio (alpha - 1)/nu. The method may also be used in other lattice theories at second order transitions.
