给出了甲醇-环己烷二元液体混合物相图混合区存在预润湿转变的证据。我们的测量结果表明，在温度T_(Pw)高于T_(S)且与分离温度T_(S)不同的温度下，随着温度向分离温度T_(S)降低，存在一级薄膜到厚膜的转变。这种转变具有很强的滞后性。所确定的预润湿线切线逼近共存曲线。此外，预润湿临界点还表现出二维伊辛临界性
We present evidence for the existence of a prewetting transition in the mixed region of the phase diagram of the binary liquid mixture methanol-cyclohexane. Our measurements reveal the existence of a first order thin to thick film transition as the temperature is decreased towards the separation temperature T S at a temperature T pw above T S and distinct from it. This transition is strongly hysteretic. The determined prewetting line approaches the coexistence curve tangentially. Also, the prewetting critical point is found to display 2D Ising-like criticality
