  1. In this paper, the study status about freeze - up of domestic and overseas was discussed first, then based on thermodynamic theories and river ice hydraulic theories, using the observed data to calculate parameters, the freeze - up forecasting mathematical model in inner mongolia reach was established. in the model, the calculating method of heat exchanging coefficient was perfected properly, and the river characteristics was quantified for the first time. the forecasting result indicated that the model precision is high, and the freeze - up forecasting formula is all - purposed

    本文首先論述了國內外有關封河研究的現狀,然後在此基礎上針對存在問題,以熱力學理論及冰力學理論為基礎,利用實資料率定參數,建立了內蒙古河段封河預數學模型,其中對熱交換系數的計算進行適當的修改,並將河條件化考慮進封河預數學模型中,證明預精確度高,且各河段預式具有通用性。
