摘要
考虑广义“食物有限”模型， 其中ｒ（ｔ）＞０在任何有限区间上可积，α＞１为两奇数之比，获得了保证方程每一正解Ｎ（ｔ）趋于１的若干充分条件，推广和改进了已有的相应结论。
We consider the generalized 'Food -limited' model. t≥0. Where r(t) > 0 t> 0, is the ratio of two odd integers, we obtain the sufficient conditions,that guarantee every positive solution of the model convergence to l as t tends to infinite some known results are improved and generated.
