发牌程序，利用MFC编写，采用双缓冲技术实现发牌和显示(Licensing procedures, written using MFC)

电子称重的实现首先是通过压力传感器采集到被测物体的重量并将其转换成电压信号。输出电压信号通常很小，需要通过前级信号处理电路进行准确的线性放大。放大后的模拟电压信号经AD转换进入主控单片机中，再将结果显示在人机界面。(The realization of electronic weighing is firstly to collect the weight of the measured object through a pressure sensor and convert it into a voltage signal. The output voltage signal is usually very small, which requires accurate linear amplification through the front signal processing circuit. The amplified analog voltage signal is converted into the main MCU by AD, and the results are displayed in the man-machine interface.)
