摘要

We report the limits of superheating of water and supercooling of vapor from Monte Carlo simulations using microscopic models with configurational enthalpy as the order parameter. The superheating limit is well reproduced. The vapor is predicted to undergo spinodal decomposition at a temperature of T-sp(vap) = 46 +/- 10 degrees C (0 degrees C %26lt;%26lt; T-sp(vap) %26lt;%26lt; 100 degrees C) under 1 atm. The water-water network begins to form at the supercooling limit of the vapor. Three- dimensional water-water and cavity-cavity unbroken networks are interwoven at critically superheated liquid water; if either network breaks, the metastable state changes to liquid or vapor.
