Moreover, single-well radial flow model, vertical stimulated fracturing model and quasi-3D multi-wells model are considered, and finite difference schemes for these models are formulated as well.

考虑了单井径向流模型、垂直压裂模型及拟三维多井模型，并给出了相应的有限差分数值模型。

Radial horizontal well is the most complicated one in horizontal well series, it has a major horizontal section and one or several branch sections.

辐向水平井是水平井系列中的高难度井，它除了有一段水平井段外，还有另外一条或多条分支井段。

Due to their design, these slewing rings can transmit radial and axial loads as well as tilting moments.

由于其设计，这些回转环可以传输径向和轴向负载以及倾斜的时刻。

So, there are 2 different things that we can compare when we're comparing graphs of radial probability distribution, and the first thing we can do is think about well, how does the radius change, or the most probable radius change when we're increasing n, when we're increasing the principle quantum number here?

当比较这些径向概率分布图,的时候，我们可以比较两个东西，第一个就是考虑当我们增加ｎ,当我们增加主量子数的时候，半径怎么变，最可能半径怎么变化？
