植物气孔蒸腾作用的流体动力学解释

A HYDRODYNAMICAL UNDERSTANDING OF TRANSPIRATION OF PLANT STOMATA

植物叶片具有很大的内表面，气孔间相互连通。当叶片表面各部位有不同风速时，气孔口间外产生压力差，由此造成空气经气孔进入叶的内表面流动，从而促进水分蒸腾和对ＣＯ＿２的吸收。

Thearea of inner surface of plant leaves is very large with numerous stomata connected withone ane another.The wind speed varies with different positions of the leaf surface,resulting inpressure dfference amon8 the stomata. Air coming into the inner surface and flowing over itfunction as ventilation,hence encouraging the transpiration of water and the obsorption of CO_2,
