| 摘 要： | 在湿润的土壤中,根毛表面形成一个圆柱形水膜套。这个弯曲的液面产生一个附加压力,这个效应在根毛的尖端大于其他部分一倍,因此能把水分、养分“压入”根系。

| Abstract: | In damp soil, cylinder-like water membrane forms on the surface of the root hair. This curve surface naturally produces additive pressure.This effect has been further verified through formulae that additive pressure on the tip of root hair doubles that on any other part of it, for it will "force" water and nutrint absorbed into the root system. |
