我们研究了由两组分混合物蒸发引起的表面张力梯度驱动的液膜的扩展。薄膜从倾斜平面上的宏观储层开始爬升，其长度L与时间t的平方根成线性关系：L（t）=（Dt）（0.5）。我们开发了一个半定量的分析，显示哪些参数控制的D值为理想的混合物和nonidealones。我们还报告了实验结果的时间演化和时空行为的界面不稳定性，开发在水库和薄膜之间的弯月面。结果与以前的实验和理论研究一致。
We study the spreading of liquid films driven by surface tension gradients induced by evaporation from a two-component mixture. The films climb from a macroscopic reservoir on a plane tilted surface and their length L is found to depend linearly on the square root of time t: L(t) = (Dt)(0.5). We develop a semiquantitative analysis that shows which parameters control the value of D for ideal mixtures and for nonidealones. We report also experimental results about the time evolution and the spatiotemporal behavior of the interfacial instability that develops at the meniscus between the reservoir and the film. Results agree well with previous experimental and theoretical studies.
