摘　　要：目的:通过测评特定低温环境新型快速上浮脱险服的保暖性能,为其后续研制和脱险人员水面待援时间的确定提供依据。方法:5名受试者穿着新型快速上浮脱险服,置于水温(-1.0±1.0)℃,气温(-2.0±1.0)℃,风速(9.0±0.2)m/s的低温环境,观察其核心体温、平均体表温度及心率变化,记录其主观感受和耐受时间。结果:5名受试者的核心体温、平均体表温度、心率均在正常范围;耐受时间均超过6 h,最长为6.5 h。结论:新型快速上浮脱险服在特定低温环境下的保暖性能可维持6 h以上,能够满足设计要求。Objective To evaluate the thermal insulation performance of a new fast buoyant ascent escape suit in a specific low temperature environment,so as to provide a basis for the subsequent development of the suit and determining the stand-by time on the surface for rescue.Methods Five subjects in new fast buoyant ascent escape suits were placed in a low temperature environment with water temperature(-1.0±1.0)℃,air temperature(-2.0±1.0)℃and wind speed(9.0±0.2)m/s.The changes of core body temperature,average body surface temperature,and heart rate were observed,and the participants’subjective feelings and tolerance periods of time were recorded.Results The core body temperature,average body surface temperature,and heart rate of the 5 subjects were within normal range.The tolerance periods of time were all more than 6 h,and the longest period of time reached 6.5 h.Conclusion The thermal insulation performance of the new fast buoyant ascent escape suit can be maintained for more than 6 hours in a specific low-temperature environment,which meets the design requirements.
