We will consider first the case of two-dimensional incompressible steady flow through orthotropic soil . 我们首先考虑二维不可压缩流体通过正交各向异性土层的定常流动。
This discussion of steady-state aerodynamics not only outlines sources of textbook material, but also provides an insight into the relatedness to other factors . 定常空气动力学的讨论不仅概述了教科书上的材料,而且提供了对有关的其它因素的看法。
