natural river model的意思|示意

This model can not only solve computational problem of hydrographic net, but also can solve computational problem of long watercourse and complex flow in natural river.

该模型既可解决复杂的河网水流计算问题，亦适用于长河段、长时段的较复杂的天然河道水流计算问题。

As a case, the model was satisfactorily structured and effectively used in computation of annual natural runoff with precipitation and evaporation at Huaibin Station on the upstream of the Huai River.

作为一个案例，该模型在淮河上游淮滨站以上流域被成功地建立，并有效地用于由降水量和蒸发量资料推求年天然径流量。

In the second part, a predator-prey model of ordinary differential with one-way diffusion is studied considering the monsoon, river flows, other natural conditions and living habits as background.

第二章以季风、河流流向等自然条件和生物生活习性为背景，建立食饵单向扩散的捕食-被捕食系统的常微分模型。
