中文说明：
在1x1的单位矩形中随机部署传感器节点，而且假设每个节点的通信半径一样，要求利用蒙特卡洛算法进行1000次试验分别模拟出连通率随节点数增加以及通信半径增加的变化趋势。
English Description：
The sensor nodes are randomly deployed in the unit rectangle of 1x1, and assuming that the communication radius of each node is the same, the Monte Carlo algorithm is required to conduct 1000 experiments to simulate the change trend of the connectivity rate with the increase of node number and communication radius.
