营养膳食+SQL+三层架构，非常适合初学者学习借鉴，参考

用Canny算子提取边缘 用Canny算子提取边缘(Using Canny edge extraction Using Canny edge extraction Using Canny edge extraction Using Canny edge extraction Using Canny edge extraction)

基于51单片机对水温进行PID控制，维持水温，水温可设定。内附Verilog代码PCB和仿真程序。(Based on 51 single-chip computer, the water temperature is controlled by PID to maintain the water temperature, and the water temperature can be set.)

用VC6.0编写的对话框程序，可以读取ECG（txt格式）数据，并画图。采用差分阈值法对心电信号进行R波的检测并显示R波检测的个数，效果较好。程序中也编写了一个滤波器对心电数据进行滤波。(VC6.0 prepared by the dialog box procedure, you can read ECG (txt format) data, and drawing. Differential threshold method ECG R-wave detect and display the number of R-wave detection, the better. The program also write a filter for filtering the ECG data.)
