This paper introduces the river ice study and project experience during freezing period mentioned above 本文对上述河冰问题的研究成果以及冰期输水的一些工程经验作了简单介绍。
If you like the cold , you ' ll enjoy sweden ' s ice hotel . located 200 kilometers north of the arctic circle , it ' s built from scratch from river ice every winter 如果你喜欢寒冷,你将喜欢瑞典的冰旅馆。位于北极圈200公里以北,它是每年冬天用河冰从零开始建的。

In order to find out safe methods for water transfer during freezing period , studying the formation and development regularity of the river ice has been concerned on by many countries 研究河冰形成和演变规律,寻求相应的解决办法保证冰期安全输水成为许多国家关心的重要问题。
On the base of the river ice study , the former ussr , canada , north europe take some effective measures to transfer water safely on their water transfer projects , and these countries have accumulated a few valuable experience 前苏联,加拿大,北欧等国家和地区结合河冰研究的成果,在引水工程中采取各种有效措施,达到了冬季安全引水的目的,积累了许多有价值的经验。
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。
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。
