| 摘 要： | 测定了在中等（100W）和高等（155W）劳动强度下，8名受试者佩戴5种自吸过滤式呼吸器（呼吸阻力及死腔不同）从事踏车运动时的呼吸模式变化。结果表明：口腔压力波动和外呼吸功因呼吸器而显著增加；随着呼吸负荷的增加，呼气压及吸气压相应增大；在呼吸负荷较大的情况下，呼气压及吸气压的增大更加显著；随运动负荷的增加，呼吸负荷对呼吸压的影响更加明显。

| Abstract: | Eight subjects wore five types of non-powered air-purifying respirators with different respiratory resistance and dead space,then they engaged in bicycle exercise test under medium(100W)and higher(155W)labor intensity,and the changes in breathing pattern of subjects were recorded to study. The result showed that,the correlation analysis revealed that the variables characterizing mouth pressure swing,extra work rate changes were highly correlated with both the phase impeded and the values of the added resist... |
