摘要：

We investigate the nonperturbative features of phi(4) theory in two dimensions, using Monte Carlo lattice methods. In particular we determine the ratio f(0) equivalent to g/mu(2), where g is the unrenormalized coupling, in the infinite volume and continuum limit. Our final result is f(0) = 11.055(24).
