摘　　要：采用曲线分段拟合方法，把我国立筒库磷化氢环流熏蒸过程中释放与降解的变化规律进行数学建模，并在IBM—PC486电子计算机上利用Mathematica2.0版本建模、求解、绘图、修匀，然后对求得的模型进行分析和检验。结果表明：函数模型（Ⅰ、Ⅱ、Ⅲ）具有良好的预测功能，能分别预测磷化氢环流熏蒸中的浓度峰值，磷化氢降解到无效低浓度熏蒸需要的时间和害虫的磷化氢熏蒸临界浓度。The test adopted the curve piecewise fitting method to build up a mathematic modelaccording to change regularity of phosphine gas release and concentration degradation in theprocess of silo recirculation fumigation. The results showed that the model has goodprediction function and can predict concentration peak value for phosphine recirculativefumigation, requiring time for phosphine degrading to the inefective low concentration andthe critical concentration for phosphine fumigating insects, respectively.
