复杂压力暴露条件下从失事潜艇快速上浮脱险后余氮张力的初步探讨

目的 探讨失事潜艇艇员在高压下暴露并从失事潜艇快速上浮脱险后体内余氮张力的计算方法.方法 对失事潜艇脱险过程进行分解,采用微积分等方法,建立脱险艇员出水时体内氮张力值的理论计算公式,并将此氮张力值换算成相对饱和深度.结果 建立的理论计算公式可以计算在7、12 m饱和后,在不同深度脱险时体内余氮张力值对应的相对饱和深度.结论 本研究建立的理论计算公式可为减压病的预测提供参考,为分析复杂压力暴露后快速上浮脱险方法的安全性提供理论依据.

Initial exploration of the body residual nitrogen tension with fast buoyancy ascent escape from the DISSUB following complicated hyperbaric exposure

Objective To discuss the arithmetic of the body residual nitrogen tension with fast buoyancy ascent escape from the DISSUB,following complicated hyperbaric exposure.Methods The processes of fast buoyancy ascent escape were analyzed,the theoretical arithmetic of the residual nitrogen tension in the body at the break of water surface was established with infinitesimal calculus,and the resulting residual nitrogen tension value was converted into corresponding saturation depth.Results The established formula could be used to calculate the residual nitrogen tension in the body at different escape depths,corresponding to saturation depths following saturation at 7 m and 12 m.Conclusions The established theoretical arithmetic could provide reference for the forecasting of DSC and could also provide theoretical evidence for the safety of fast buoyancy ascent escape following complicated hyperbaric exposure.
