惰性气体不对称动力学在潜水减压计算中的应用

摘要

Objective To explore the application of asymmetric kinetics of physiological inert gases in diving decompression algorithm.Methods Considering that the actual desaturation in the human body was slower than the saturation process,the kinetic equations of different saturation and desaturation rate of inert gases were constructed with piecewise functions on the basis of the original single exponential kinetic equation.The results were compared other adjustment methods.Results With the application of asymmetric kinetics, the time at each decompression stop was prolonged for an approximately equal proportion, remained unchanged at some deeper and shorter stops.Conclusion Asymmetric kinetics can more closely simulate the gas movement in the body to effectively control the conservativeness of decompression,and adapt to different decompression requirements by adjusting the half-saturation time ratio.%目的 探索惰性气体不对称动力学在潜水减压算法中的应用.方法 在原有单一指数式动力学方程的基础上,根据机体内气体脱饱和慢于饱和的客观现象,采用分段函数分别构建饱和与脱饱和过程气体动力学方程,建立饱和-脱饱和临界点计算指数方程,构建不对称算法,并对比分析计算的减压结果.结果 应用不对称动力学后各减压站停留时间近似等比例延长,部分较深且时间较短的站停留时间维持不变.结论 不对称动力学可更近似地模拟体内气体运动规律,有效控制减压保守度,并可通过调节半饱和时间比以适应不同减压需求.
