摘要
本文是文［５］在ｎ＝２时更进一步的讨论．模型由一个种群构成，此种群可在两个毒素环境中生存，且种群扩散仅与其所在生存环境中的（数量）密度决定．得到了比文［５］更精细的结论．
This paper is the further discussion of paper [5] when n = 2. The system consists of only one specy, but this specy can live in two polluted eviroments. The deffusion is correpondent with the density in the eviroment. We discussed the strong perslstence. week persistence and extinction. We obtained the better results than paper [5].
