摘要
目的:探讨催化模型在血吸虫病粪检阳性率年龄分布资料分析中的应用。方法:采用非线性最小二乘法对四川省西昌市川兴监测点的2000年血吸虫病监测数据进行拟合,确定催化模型。结果:结合资料特点和模型的适用条件,并经分析比较确定模型y=17·00(e-0·0255t-e-0·0270t)为拟合该资料较优的模型。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。
Objective: To probe into applying catalytic models to the positive rate of stool examination age distribution data of schistosomiasis. Methods: The data weve collected from Xichang city, Sichuan provincial surveillance spot in 2000. To get the catalytic models, the data were fitted with nonlinear least squares. Results: Comidering the data characteristics and the application conditions of models, the model y= 17.00 (e^-0.0255t - e^-0.0270t) was ascertained finally, which fits the data better. Conclusion: Applying catalytic models to fit the positive rate of stool examination age distribution data of schistosomiasis, two - stage catalytic model is much better.
