The case study shows that SP model is convenient and effective, and that SP model can be applied to mid and long termprediction of many runoff processes.
实例研究的结果说明，SP模型简便、实用性强，可在径流中长期预测中广泛应用。

Conclusion GM (1, 1) model can be well used to the short termprediction of Cardiocerebrovascular disease, but it is not very well in midterm or long term prediction.
结论GM(1,1)模型能够较好的用于疾病死亡率的近期预测，而中长期预测的效果不太理想。

The result shows that there are obviously anomaly zones of a value with better prediction ability, in midterm of 2 ~ 3 years before most moderately strong earthquakes.
