目的:建立实时减压方案的理论计算方法。方法:根据Haldane理论n [n 1]n ，确定适合实时安全减压方案计算的假定时间单位、理论组织分类、氮过饱和安全系数及其选取方法，建立实时安全减压方案的计算方法；通过112只羊次，28个加压方案观察动物出舱后的行为学改变并检测多普勒气泡音。n 结果:出舱后动物均未出现行为学异常，多普勒血流气泡音检测均为零级。结论:理论计算得到的减压方案安全可靠。“,”Objective:To establish a theoretical calculating method for real-time safe decompression scheme.Methods:Based on the Haldane theory, this research determined the assumed time unit, theoretical organization and classification, safety factor of nitrogen supersaturation and its selecting method, which were suitable for real-time safe decompression scheme calculation, and established a calculating method for real-time safe decompression scheme, then validated that calculating method by observing the behavioral change and detecting Doppler bubble sound with 112 sheep/times and 28 pressurization schemes.Results:There was no behavioral abnormality in all the animals after leaving cabin, and the results of Doppler blood bubble sound detection were zero level.Conclusion:The decompression scheme obtained by theoretical calculation was safe and reliable.
