One of the basic assumption of the simple catalyticmodel is that during the period of the diseases prevalence, the force of infection is a constant.
简单催化模型的一个基本适应条件是:在疾病流行期间其感染力保持恒定。

Conclusion: Applying catalytic models to fit the positive rate of stool examination age distribution data of schistosomiasis, two-stage catalyticmodel is much better.
结论:应用催化模型拟合血吸虫病粪检阳性率的年龄分布资料,两级催化模型较为合适。

The results showed that the model complexes the high catalytic activity was high.
