图1：CT扫描显示了一个右侧顶叶囊性结构伴有中心点状高密度影代表一个头节（箭头）。

Figure 1: CT scan demonstrates a right-sided parietal lobe intraaxial cystic structure with a central "dot" representing a scolex (arrow).

其中一个理解它的方法，就是通过看这个密度点图，这里点的密度，和概率密度想关联的。

So, one way we could look at it is by looking at this density dot diagram, where the density of the dots correlates to the probability density.

本研究的平均图距还较大，有待于进一步深化，以期构建出一张标记分布均匀，位点密度较高的长果种黄麻遗传连锁图谱。

In this study, the average map distance is too large, which requires to be further deepened for building a genetic linkage map of Jute with evenly-distributed markers and high-density sites.

So, doing those probability density dot graphs, we can get an idea of the shape of those orbitals, we know that they're spherically symmetrical.

概率密度点图上,我们可以对这些轨道的形状，有个大概了解,我们知道它们是球，对称的,我们今天不讲。

It looks like we hit zero, but we actually don't remember that we never go all the way to zero, so there's these little points if we were to look really carefully at an accurate probability density plot, And then, for example, how many nodes do we have in the 3 s orbital?

但其实没有，记住，我们永远不会到零,如果我们，在概率密度图上,非常细致的看这些点的话,它永远不会到零，在3s轨道里，有多少个点呢？，2个，正确？
