摘要
在半衰期为 78秒的 4 5号仓和半衰期为 5 4秒的 4 9号仓进行环流熏蒸效果对比试验 ,试验结果表明 ,气密性越好 ,维持PH3气体有效浓度的时间越长 ,熏蒸效果也越好。
Recirculation fumigation were tested in two large warehouses which decline half-degradation time were 78s and 45s respectively.The results showed that the better gastightness the warehouse have,the longer time the PH 3 effective concentration can maintain,and the better fumigation effect can be achieved.
