严寒季节野战生存、训练及战斗状态下,野战坑道和帐篷取暖与 CO_2浓度增加是野战部队面临的两大难题。据报告,乡村大气中CO_2浓度为0.03%,当 CO_2浓度升高到3%时,人员会出现不适、气喘、头痛等,使工作效率减低。为探讨严寒条件下坑道、帐篷内如何取暖及 CO_2能达到什么浓度,对人员会造成何种影响,我部于1997—12—18在延边地区冬训时进行了观测,现将结果报告如下。
Under the conditions of field survival, training and combat in the cold season, the heating of field tunnels and tents and the increase of CO 2 concentration are two major problems that field forces face. It has been reported that the concentration of CO 2 in the rural atmosphere is 0.03%. When the CO 2 concentration is increased to 3%, the staff may experience discomfort, asthma, headache and the like, thereby reducing the work efficiency. In order to explore the tunnel under harsh conditions, how to heat the tent and what concentrations of CO2 can be achieved on the staff will affect what, I Department in 1997-12-18 in Yanbian during winter training was observed, the results are reported as follows.
