摘　　要：在镀膜生产中,镀膜的厚度是镀膜质量的关键,利用自制的基于USB接口的数据采集系统成功实现了对镀膜反射率的计算,实验证明:该采集系统的采样频率为110K/S,采样精度为30.5μV。通过良好的人机交互界面,方便地控制镀膜时间,极大提高了生产效率。During the production of coating, the thickness of coating is the key factor of the production quality. We have succeeded in calculating the reflectivity of coating by using the data sampling system which based on USB interface. Finally the result given by experiment shows that the sampling frequency is ll0K/S and the sampling precision is 30.5μV. We can control the coating cycle conveniently and enhance the productivity greatly by using the application program.
