摘要: 采用动力学Monte Carlo 方法研究了二层Ising模型的临界性质及早期动力学标度行为.结果表明层间耦合不为零时也存在临界点；计算了早期动力学临界指数θ;估计了传统的临界指数1/νz.其结果支持临界线存在的猜想，并表明此模型很可能是一种弱普适模型.
Abstract: Monte Carlo simulations of critical dynamics has been used to study the short-time process and scaling behavior of two-layer Ising model. The result shows that there are critical points even when the coupling between the two layers is not equal to zero; the short-time dynamic critical exponent θ was determined; the traditional critical exponent 1/νz was estimated also.Our result encouraged the supposition of the existence of the critical line and evidenced that this model was likely a weak universal model.
