By research on the concentration change and distribution of methyl bromide in the container, we found that in the first period of fumigating, the absorption of the goods to methyl bromide became quickly, so did the concentration decline of the fumigant because of leakage of the carton itself. The distribution of the fumigant is not uniform in the aclinic and vertical directions. The absorption of the goods to methyl bromide completed after 6 hours delivered the gasified fumigant and the distribution of the concentration in space got balance.

对溴甲烷在集装箱内浓度的变化与分布规律进行研究，发现熏蒸开始阶段，货物对熏蒸剂的吸附及箱体渗漏使气体浓度下降较快，且在水平和垂直方向都存在分布不均匀的现象，气化投药后6小时，货物对溴甲烷的吸附已基本完成，浓度空间分布达到平衡。
