The mutual diffusional interference between adjacent stomata in laminar flow over a leaf is shown to play a decisive role in determining overall transpiration. The magnitude of this interference varies with the interaction of the vapor diffusional shells forming above each stoma and the air flow over the leaf. The interference decreases with increasing incident radiation and wind velocity. The effect of interference on the stomatal resistance to diffusion plays a major role in the overall variations in transpiration.
层流掠过叶片时，相邻气孔间的相互扩散干扰对总蒸腾作用起决定性作用。这种干扰的大小随每个气孔上方的蒸气扩散壳与叶片上方的气流相互作用而变化。干扰随入射辐射和风速的增加而减小。扩散阻力对干扰的影响在总蒸腾作用的整体变化中起着重要作用。
