我国北方地区冬季漫长，寒冷干燥，建筑物大都用双层塑钢窗来保温。由此引出1个数学问题，即比较双层玻璃和单层玻璃的热量传导的差别，从而找到安装双层玻璃的工作原理。
我國北方地區鼕季漫長，寒冷榦燥，建築物大都用雙層塑鋼窗來保溫。由此引齣1箇數學問題，即比較雙層玻璃和單層玻璃的熱量傳導的差彆，從而找到安裝雙層玻璃的工作原理。
아국북방지구동계만장，한랭간조，건축물대도용쌍층소강창래보온。유차인출1개수학문제，즉비교쌍층파리화단층파리적열량전도적차별，종이조도안장쌍층파리적공작원리。
It is dry and cold in the long winter in Northern China, with most building adopting double steel windows as the warmth insulator, which results in a mathematical problem, the differences between the heat conduction of double glazing and single glass, leading to the working principles of the installation of the former.
