单片机向串口发送汉字，超级终端为啥显示是乱码？
效果如下：
绀哄姛浠浇鑽风數鍘嬫槸: 1497mV
Channel '1' voltage is 1835mV
Channel '2' voltage is 1270mV
鍔犻€熷害浼犳劅鍣ㄧ數鍘嬫槸: 2426mV
Channel '4' voltage is 1524mV
Channel '5' voltage is 4mV
Channel '6' voltage is 657mV
鐢垫睜鐢靛帇鏄? 2394mV
Channel '8' degree is 160.139800

sprintf(main_buf,"Channel '%d': %s %5.1fmV ",i,sgy_jsd_volt, voltage);
SimUart1_WriteString(main_buf,strlen(main_buf));
Channel '1' voltage is 4.8mV
Channel '2' voltage is 4.8mV
Channel '3': 加速度电压值是 9.6mV
Channel '4' voltage is 9.6mV
Channel '5' voltage is 0.0mV
Channel '6' voltage is 4.8mV
Channel '7': 电池电压值是 1134.1mV
Channel '8': 芯片的内部温度值是 34.9
