5.3    变换始终节点模块功能
变换始终节点模块主要是设置每次实验的开始节点和目标节点。
代码如下：
iiii++;
            if (iiii == 2)
            {
                qd.x = 90;
                qd.y = 20;
                zd.x = 140;
                zd.y = 60;
                MessageBox.Show("变换成功");
               
            }

            else if (iiii == 3)
            {
                qd.x = 90;
                qd.y = 20;
                zd.x = 270;
                zd.y = 80;
                MessageBox.Show("变换成功");
              
            }
            else if (iiii == 4)
            {
                qd.x = 80;
                qd.y = 50;
                zd.x = 270; 无线传感器网络中数据传输最优路径选择(10):http://www.751com.cn/tongxin/lunwen_2234.html
