Moreover, the synchronization of EAN is studied; the result shows that the stochastic networks are more poorly synchronized than their deterministic counterparts. These models can well mimic some real systems. Firstly, two dimensional random Apollonian networks and two dimensional EAN are maximal planar graphs, which may be helpful for designing printed circuits. Secondly, V-HDRAN can be mapped into the Yule process, which was inspired by observations of the statistics of biological taxa. From this perspective, V-HDRAN can find some applications in biological systems. Thirdly, all networks of this type consist of complete graphs; this particularity of the composing units can provide a comprehensive aspect to understand some real-life systems making up of complete graphs, such as movie actor collaboration networks, scientific collaboration networks and networks of company directors.

这些模型可以很好地描述现实系统，其中二维随机阿波罗网络与二维演化的阿波罗网络为最大平面图，这对印刷电路板等现实系统的设计有重要的借鉴作用；变体模型V-HDRAN的构建过程与Nature上发表的关于生物物种的形成过程之间存在一个一一对应的关系，这对生物系统的建模有重要的价值；另外，这类网络均由完全图组成，它们对由完全图组成的电影演员合作网、科学家合作网、公司董事网等由完全图构成的现实网络的建模有重要的理论意义和应用价值。
