受有机发光二极管显示器工业化制造的启发，我们建立并分析了较一般形状的浅井在触地前后薄滴演化的数学模型，该模型考虑了流体在空间上的不均匀蒸发，用三个不同长宽比的圆柱形井进行了物理实验，并与圆柱形井的相应理论预测进行了比较，验证了数学模型的正确性。
Abstract Motivated by the industrial manufacture of organic light-emitting-diode displays, we formulate and analyse a mathematical model for the evolution of a thin droplet in a shallow axisymmetric well of rather general shape both before and after touchdown that accounts for the spatially non-uniform evaporation of the fluid, perform physical experiments using three cylindrical wells with different small aspect ratios, and validate the mathematical model by comparing the present experimental results with the corresponding theoretical predictions for a cylindrical well.
