根据高原部队特殊性和驻地环境特点，为了探讨部队由海拔较低的营区，进入海拔较高的坑道及在封闭坑道作业时，人体血气分析各参数的变化，我们在某部发射旅和装检团坑道驻训期间，跟踪调查了部分人员血液气体与酸碱平衡参数，同时对坑道内大气压、氧含量进行了测定，旨在探讨 According to the special characteristics of the plateau troops and the characteristics of the resident environment, in order to investigate the changes in the parameters of the human blood gas analysis conducted by the troops entering the higher-altitude tunnels and the operation of the closed tunnels, During the training period of the tunnel, the parameters of blood gas and acid-base balance of some staff were traced and investigated, and the atmospheric pressure and oxygen content in the tunnel were measured at the same time.
