联接CHESTAC-35F型肺功能机的Apple-Ⅱ微电子计算机上采用BASIC语言编制程序,建立了用力呼气容积-时间曲线的时间常数直方图分析方法。在模拟实验中,复原前后的直方图误差不超过一个直方柱
The BASIC language program was used to connect the CHESTAC-35F lung function machine to the Apple-Ⅱ microcomputer, and the time constant histogram analysis method of forced expiratory volume-time curve was established. In simulation experiments, the histogram errors before and after restoration do not exceed one histogram
