摘　　要：[目的]探讨石棉工人肺弥散量(DL_(CO))和残气功能动态变化特点。[方法]对某石棉制品厂健康石棉工人和石棉肺患者分别于1984、1989进行了二次肺弥散量和残气功能追踪测定。[结果]石棉工人DL_(CO)随接尘年限的增加而下降,石棉肺患者弥散功能的进行性损害快于健康石棉工人;同时结果提示,石棉粉尘影响肺残气功能,但尚不能认为随接尘时间的增长残气功能进行性损害。[结论]石棉工人DL_(CO)随接尘年限的增加而下降,而石棉工人接尘年限对残气功能的影响不明显。[Objective]To discuss the characteristic of dynamic changes of pulmonary diffusing capacity and residual volume function in asbestos workers. [Method]Both healthy workers and asbestos lunge patients in a asbestos factory were investigated in 1984 and 1989 to examine their pulmonary diffusing capacity and residual volume function. [Result] Asbestos workers' DLco decrease as the growing of working time. Impairment of pulmonary diffusing capacity in asbestosis patient group was faster than that in healthy asbestos workers. At the same time the results indicated that asbestos dust affects pulmonary residual volume function, but we can not consider that residual volume functioning asbestos workers have progressive impairment as asbestos exposure duration increased. [Conclusion]DLco and asbestos exposure duration didn't affect obviously residual volume function.
