分析二维正方格子上的逾渗问题，通过编写程序，得到临界概率 P 及临界指数 (PS:程序功能简单介绍:yushen.m 中计算了 Pinf 和 p 的关系，yushenmain.m 调用 yushen.m 来 计算不同 p 下的 Pinf;yushenhuixuan.m 中计算了 Rs 和 p 的关系，yushenmain2.m 调用 yushenhuixuan.m 来计算不同 p 下的 Rs。具体的实现程序中均有注释。)(The percolation problem on two dimensional square lattice is analyzed, and the critical probability P and critical exponent are obtained by programming. (PS: program functions simply: the relationship between Pinf and P is calculated in yushen.m, yushenmain.m is called yushen.m to calculate Pinf under different p; the relationship between Rs and P is calculated in yushenhuixuan.m, and yushenmain2.m invokes to calculate the differences under different P. There are annotations in the specific implementation program. ))

通信双方以客户-服务器方式建立TCP连接，用于双方信息的相互提交。当信道上没有数据传输时，通信双方应每隔时间C发送链路检测包以维持此连接，当链路检测包发出超过时间T后未收到响应，应立即再发送链路检测包，再连续发送N-1次后仍未得到响应则断开此连接。(Both sides of communication establish TCP connection in client-server mode for mutual submission of information. When there is no data transmission on the channel, both sides of the communication should send link detection packages every other time C to maintain this connection. If the link detection packages do not receive a response after sending out more than time T, the link detection packages should be sent immediately, and then the link detection packages should be disconnected if they have not received a response after sending N-1 consecutive times.)
