目的 研究模拟航空器气调检疫处理现实可行条件下, 应用不同气调处理技术对小白鼠的致死效果.方法 将小白鼠随机分组置于模拟实验装置中 (实验用鼠共75只), 分别持续通入不同浓度氮气和高温空气进行处理, 氮气流量选取6、9和12 L/min 3个流量梯度, 流量差在±0.5 L/min;高温空气选取60、120和180 L/min 3个流量梯度, 流量差在±2 L/min, 观察了小白鼠的死亡时间.结果 小白鼠的死亡时间随着通入氮气的浓度和流量的增加而缩短, 不同浓度组以及不同流量组间比较, 差异有统计学意义;小白鼠的死亡时间随着通入高温空气流量的增加而显著缩短, 不同位置以及不同流量组间比较, 差异有统计学意义.结论 98％以上浓度氮气和高温空气可快速有效致死小白鼠, 在有效性和可行性上可以成为探索现有航空器检疫处理的替代方法.“,”Objective To study the lethal effect of different type controlled atmosphere (CA) treatments on mice in simulated aircraft controlled atmosphere quarantine treatment. Methods A total of 75 mice were divided into several experimental groups, and feed in the experimental containers with different concentration of nitrogen or high temperature air. Three nitrogen flow (6, 9, 12 L/min) were set and flow bias about ±0.5 L/min was permitted. High temperature flow was set at 60 L/min, 120 L/min and 180 L/min which may had temperature bias of ±2 L/min. The death rate and mortality of mice during each experiment were observed. Results The death time of mice was shortened significantly with the rising of density and flow of nitrogen. The difference between different concentration and flow groups was statistically significant. The death time of mice was shortened significantly with the rising of density and flow of high temperature. The difference between different position and flow groups was statistically significant. Conclusion Two types of controlled atmosphere (CA) treatments on mice with 98％ nitrogen and high temperature of air showed lethal effect on mice. It could be an alternative method to explore the aircraft quarantine treatment from effectiveness and feasible aspect.
