胡南琦同志: 您好! 十分高兴收到由《物理教学》编辑部转来您的复信。谢谢。阅后您的来信,感到贵文的解释不太完美。水处于高温时其冷却速率固然较大,但它们在冻结之前必须经过一系列过渡温度。此时情况又怎样呢?我抱有许多疑 Comrade Hu Nanqi: Hello! I am very pleased to receive a letter from the “Physics Education” editorial department. Thank you. After reading your letter, I feel that the explanation of your article is not perfect. When the water is at a high temperature, the cooling rate is certainly high, but they must pass through a series of transition temperatures before freezing. What happened at this time? I have many doubts
