采用分光光度法研究了偏二甲肼动态配气系统的稳定性。实验结果表明,在环境温度、载气温度和流量恒定的情况下,该动态系统可稳定地输出0～100mg/m~3的偏二甲肼标准气体,可用于肼类推进剂监测仪器的标定与校验;该配气系统还可用于制备用静态法难以配制其它极性化合物标准气体。
The stability of UDMH dynamic gas distribution system was studied by spectrophotometry. The experimental results show that the system can stably output 0 ~ 100mg / m ~ 3 UDMH standard gas at constant ambient temperature, carrier gas temperature and flow rate, which can be used for the calibration of hydrazine propellant monitoring instruments And calibration; the gas distribution system can also be used to prepare the static method is difficult to formulate other polar compounds standard gas.
