the gray dynamic model

By adopting the method of looking over the tickets of passengers and recording the time when they enter the stations, a waiting time model is established on the basis of the gray dynamic theory.

通过实际查验旅客车票并同时记录该旅客的进站时间，基于灰色动态理论，建立旅客的候车时间模型。

Therefore, the dynamic gray forecast model had higher value than static model in dam deformation forecast.

因此，动态灰色预测模型在大坝变形的预测预报中比静态预测模型具有更高的应用价值。

Based on the test data under dynamic water and static water, main factors which influence the fine sediment flocculation are analyzed using the relative analysis theory of the gray model analysis.

根据静水和动水条件下的细颗粒泥沙沉降试验结果，应用灰色模型分析中的关联度分析理论，分析了影响细颗粒泥沙絮凝沉降的主要因素。
