摘　　要：采用平地测试和攀爬楼梯、扶梯测试两种方式,进行穿着战斗服行进和穿着密闭防化服行进、负重、救人等多种测试,对消防部队常用的空气呼吸器的供气性能进行实验测试。测得连续作业条件下的最长供气时间、不同作业条件下的单位时间耗气量,对比平地与攀爬情况下的单位时间耗气量及心率变化。分析测试数据,得出测试结果,归纳便于实战应用的供气性能参考数据及规律。同等距离攀爬楼梯时的单位时间耗气量可以参照平地行进数值的2倍计算。建议空气呼吸器配置备用气瓶或备用气源。The experimental test of the air SUpply performance of air breathing apparatus used by the fire forces was carried out by field test and stair climbing test. The test included move with firefighting suit and move, load bearing and life rescue with airtight chemical protective suit. The longest air supply time and air consumption under different conditions were test- ed. The air consumption in unit time and pulse change of ground movement and climbing were compared. Based on the a- nalysis of the test data, the test results were obtained. The ref- erence data and the law of the air supply performance for the practical application of the actual combat were summarized. The air consumption in unit time of climbing could be calculated as 2 times of that of ground movement. The spare gas cylinders or spare air sources for air breathing apparatus were suggested.
