研究了波动对一维一阶相变朗多-金兹堡模型的影响。可以得到非常尖锐的伪跃迁。发现过渡的临界区域或宽度随系统横截面上相互作用单元的有效数量呈指数型消失。结果在朗道-利夫希茨证明的背景下进行了物理解释，证明在一维中不可能存在相平衡。
The effect of fluctuations on a Landau-Ginzburg model of a first-order phase transition in one dimension is studied. Extremely sharp pseudotransitions can be obtained. The critical region or width of the transition is found to vanish exponentially with the effective number of interacting units across a cross section of the system. The results are physically interpreted in the context of the Landau-Lifschitz proof that phase equilibrium is impossible in one dimension.
