Query: Critical region of the random bond Ising model   We describe results of the cluster algorithm Special Purpose Processor
simulations of the 2D Ising model with impurity bonds. Use of large lattices,
with the number of spins up to $10^6$, permitted to define critical region of
temperatures, where both finite size corrections and corrections to scaling are
small. High accuracy data unambiguously show increase of magnetization and
magnetic susceptibility effective exponents $\beta$ and $\gamma$, caused by
impurities. The $M$ and $\chi$ singularities became more sharp, while the
specific heat singularity is smoothed. The specific heat is found to be in a
good agreement with Dotsenko-Dotsenko theoretical predictions in the whole
critical range of temperatures.
