白天蒸腾作用散失的水分超过根系吸收的水分，因而叶子的水势就下降。

During the day water loss by transpiration exceeds water absorption by the roots and leaf water potential decline.

比较实际观测资料，双水分子对于大气吸收和水汽总含量的非线性关系有作用，但造成此非线性关系，仍有其它因素。

In comparison with experimental data, the dimer water vapour is a factor of nonlinearity between the relationship of atmospheric absorption and total water vapour content, but it is not the only one.
