摘　　要：我们以证据理论为核心建立数学模型，以ＶｉｓｕａｌＢａｓｉｃ为计算机应用开发工具，实现了一个计算机辅助肺功能分型诊断系统。系统能够根据患者的相关指标的检测值作出阻塞型通气障碍、限制型通气障碍、混合型通气障碍或正常的诊断。在对本文所收集的２９０ 例原始病例所作的回代验证中，系统诊断符合率达到９３．１％ ，取得了较为满意的效果。This article expounds the main idea of the evidence theory and hence presents a mathematical model.Based on the above work,we have developped a computer aided medical differential diagnosis system with Visual Basic.The system can identify restrictive ventilatory impairment,obstructive ventilatory impairment,mixed ventilatory impairment and normal.according to the valuse of patients' related indexed. In a retrospective test of 290 cases we collected,the rate of agreement between the diagnosis made by this system and the physicians was 93.1%.
