In the presence of large thermal fluctuation, conditions that RF-SQUID in the dissipa-tive mode can be properly operated are analysed, the flux transition distribution densities are obtained, thus the mean value and the width of transition are derived. Finally we find that the-effective critical current of RF-SQUID loop is greatly reduced by large fluctuation and the transition width can be determined with a simple equation.
