The Gray Prediction Model for the Spread Period of Schistosomiasis
血吸虫病蔓延周期的灰色预测模型

It is of great importance to predict the spreading peak of schistosomiasis. This paper establishes a difference gray prediction model, which forecasts the peak peroid of schistosomiasis growing and spreading. A practical example is caculated and analyzed, which indicates that the prediction result is correct and the precision grade of the model is excellent.
