利用液体纳米层模型计算树高极限的新方法
A new approach for the limit to tree height using a liquid nanolayer model
摘要：
与固体接触的液体受到分子间力的作用，从而在壁处产生密度梯度。范德华力使液体不均匀，应力张量不再像均匀块体那样是球形的，并且可以获得稳定的薄液膜，润湿垂直壁直到不可压缩流体模型无法预测的高度。应用于木质部的微管，可以理解为什么树液的上升是可能的非常高的树木，如红杉或巨桉。
英文摘要：
Liquids in contact with solids are submitted to intermolecular forces inferring density gradients at the walls. The van der Waals forces make liquid heterogeneous, the stress tensor is not any more spherical as in homogeneous bulks and it is possible to obtain stable thin liquid films wetting vertical walls up to altitudes that incompressible fluid models are not forecasting. Application to micro tubes of xylem enables to understand why the ascent of sap is possible for very high trees like sequoias or giant eucalyptus.
