This paper argues first that atomic parts of a connected circulargraph are still connected circular graphs. It also gives some natures about connectivity of connected circular graphs.
本文首先得到了循环图的原子部分仍为连通循环图的结果，同时还得到了连通循环图的连通度的一些性质。

This is a surprising fact, given that circular references are a common occurrence for almost any persistent object graph.
这很让人意外，因为循环引用几乎出现在所有的持久化对象图中。

Then, use GraphViz to generate the graph image (here, using circo, which specifies a circular layout). The process of generating this image is defined as follows.
