freeze-up forecast meaning in English
冻结预报
封冻预报
Examples
- Because the complexity of ice evolvement and it was late to start studying river ice in our country , now the freeze - up forecasting precision ca n ' t satisfy the need of preventing ice flood and the freeze - up formula of every reaches is different , being not all - purpose
由于冰凌演变的复杂性及我国冰情研究起步较晚，现在的预报精度尚不能满足防凌需要，且各河段封河预报公式不同，没有通用性。 - For the study of freeze - up forecasting model in in inner mongolia reach , now it changed to combining theories and experiences from statistic model . now most of the freeze - up forecasting methods are based on combining theories and experiences , and then correcting properly with time
对于内蒙古河段封河预报模型的研究，经历了从数理统计到理论与经验相结合的阶段，现行预报方法多是以理论与经验相结合为基础，并进行适当的实时修正。 - 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
本文首先论述了国内外有关封河研究的现状，然后在此基础上针对存在问题，以热力学理论及冰水力学理论为基础，利用实测资料率定参数，建立了内蒙古河段封河预报数学模型，其中对热交换系数的计算进行适当的修改，并将河道条件量化考虑进封河预报数学模型中，证明预报精确度高，且各河段预报公式具有通用性。
