摘　　要：从道尔顿分压定律和理想气体的状态方程出发,导出肺功能仪在不同环境条件下的体积修正公式,对影响肺功能仪校准准确度的温度和大气压力等因素进行了讨论分析,结果表明温度和大气压力对测量结果有显著影响。该研究对实际校准工作有一定的借鉴作用。Volume correction formulas for spirometer were derived according to the different atmospheric environmental conditions and human lung environmental conditions. The temperature and atmospheric pressure that affected the calibration accuracy of spirometer were discussed and analyzed. The results showed that the temperature and atmospheric pressure had a significant impact on the measurement results. The research has a certain reference for the actual calibration work.
