图1. 扩散方程中6种元素通量随时间的变化趋势。c∝是初始浓度, 6种元素的初始浓度分别为5、0.046、0.1、0.0029、0.001、0.008 μmol·cm-3; Ftot(t)是养分吸收通量; t是时间, 以25天为例。
Fig. 1. Changes in the fluxes of six elements with time in diffusion Nye-Tinker-Barber model. c∝ is the initial concentration, with given values of 5, 0.046, 0.1, 0.0029, 0.001, 0.008 μmol·cm-3 for the six elements; Ftot(t) is the element uptake flux; t is time, with a duration of 25 days as an example.
