| 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）从事踏车运动时的主观舒适度。结果表明：随着呼吸负荷增大，受试者的主观不适度显著增强；在中等运动负荷条件下，高温环境中人员对呼吸负荷主观不适度的反应更加明显；在高运动负荷条件下，常温环境人员对呼吸负荷主观不适度的反应更加明显。

| Abstract: | Eight subjects wearing five types of non-powered air-purifying respirators with different respiratory resistance and dead space were engaged in bicycle exercise test under medium(100W) and higher(155W) labor intensity,and the subjective well-being of subjects were recorded and analyzed.The result showed that the degree of subjective uncomfortableness of subjects increased with increasing inhalation resistance,and it increased in the hot environment under the condition of medium labor intensity.On the other ... |
