我们研究了人类角膜前泪膜的引流。建立了考虑蒸发和重力作用的水层排水流体动力学模型。该模型可以简化为一个单一的非线性偏微分方程。对方程进行了数值求解，得到了符合实际参数的准确破膜时间。结果表明，虽然重力和蒸发在膜的某些部分不是最主要的影响，但它们仍然会对膜的排水过程产生重大影响，因此应将其纳入泪膜排水模型中。
We study the drainage of the precorneal tear film in humans. A fluid dynamic model for the drainage of the aqueous layer is developed that includes the effects of evaporation and gravity. The model may be reduced to a single nonlinear partial differential equation for the thickness of the aqueous layer. The equation is solved numerically and accurate times for film rupture are obtained for physically realistic parameters. The results indicate that although gravity and evaporation are not the most dominant effects in some parts of the film, they can nevertheless materially affect the film drainage process and should therefore be included in models for tear film drainage.
