Adjacency matrix data of the virtual airport network.

There are four sheets in this table that store the critical matrix data of four virtual airport networks: A1, A2, A3, and A4. Among them, rows and columns represent airports, 0 in the matrix represents no flight route between two airports, and 1 represents a flight route between two airports. (XLSX)本表格包含四个工作表，用于存储A1、A2、A3、A4四个虚拟机场网络的关键矩阵数据。其中，矩阵的行与列均代表机场；矩阵内取值为0表示两个机场之间无航班航线，取值为1则表示二者存在航班航线。本数据集文件格式为XLSX。
