保溫隔熱實驗：
Thermal insulation test:
分別做了兩個大小厚度都相同的磚混結構房屋和輕鋼結構房屋，到專業的實驗室去做測試，看他們之間的溫差到底有多少？
Two brick concrete structure houses and light steel structure houses with the same size and thickness were made respectively, and they were tested in a professional laboratory to see how much the temperature difference between them was?
保溫箱里的溫度將持續下降到零下30℃，實驗顯示在降溫過程中，輕鋼結構里面的溫度和磚混空間里面的溫度差一直保持在13℃左右。
The temperature in the incubator will continue to drop to minus 30 ℃. The experiment shows that during the cooling process, the temperature difference between the light steel structure and the brick concrete space has been maintained at about 13 ℃
