摘要：

Explanations are given for why there is no real first-order phase transition in the one-component plasma (OCP) model. The fluid (liquid) and crystalline states of the OCP observed in computer experiments are not in equilibrium, on account of instability of the system. However, specific features of the free energy suggest that some sort of a "virtual" phase transition occurs in the model. Such a transition can be turned real by choosing the right form of the background energy. (C) 1998 American Institute of Physics. [S0021-3640(98)01601-6].
