本文提出了一种求解Hele-Shaw盒中粘性指状物宽度的Saffman-Taylor问题的解析方法。第一个目的是提供一个系统的描述的方式，其中引入毛细力的奇异摄动导致模式选择的可解性机制。然后说明Couder等人（1986）最近的实验观察如何可以用这种机制所暗示的术语来解释。
An analytic approach to the Saffman-Taylor problem of predicting the width of a viscous finger in a Hele-Shaw cell is presented. The first purpose is to provide a systematic description of the way in which the singular perturbation introduced by capillary forces leads to a solvability mechanism for pattern selection. It is then shown how recent experimental observations by Couder et al. (1986) may be interpreted in terms suggested by this mechanism.
