摘　　要：通过研究冰与水交界面附近温度场分布情况为找到冰情检测新方法及研究冰水转化提供理论指导。在水域投入冰后,对冰-水热传导影响冰水交界面附近温度变化进行了检测。对离冰水交界面在5~9cm、-4~0cm、0~4cm、-5^-9cm处温度分布研究拟合得到点距冰与水交界面距离与温度关系函数,数据验证,拟合值与监测值误差在±(0.1~0.3℃)。当冰与水交界面温度场引起附近温差越大,冰水转化越快,易引发冰情。Through the study of ice and water temperature distribution near the interface, a new method of ice detec- tion is found and the theoretical guidance is provided for the research of ice and water transformation. By putting the ice into the water, the ice-water heat transfer have an effect on the water temperature near the interface. Through the study of the temperature distribution, which is 5~9cm,0~4cm,-4~0cm,-5— -9cm to the ice water interface, the fitting section function is got, which named relation function of points from ice and water interface between the distance and tem- perature. The fitting values and monitoring error is between _±0. 1~0. 3℃. The temperature difference of ice and water interface is bigger; the ice change into water is faster, which is more easily leaded to ice.
