窗是一幅既生动而又变幻无穷的画幅。一年四季,风雨明晦,烟岚晓色,远山近廓,繁花落叶,都可以从窗中窥见。因此,有人称窗为“无心画”。窗不但是取景框,更主要的作用是阳光和空气进入室内的通道。开窗要大小合度,光照适宜,空气流畅。开得过大,夏天日晒强烈,易使人疲倦;冬季热损失大,增加烤火费 The window is a picture that is both vivid and ever-changing. Throughout the year, the weather is bright, the smoke is bright, the mountains are near, the flowers are fallen, and you can see through the windows. Therefore, some people call the window “unintentional.” The window is not only the frame, but also the main function of the sun and the passage of air into the room. Open the window to size, light is suitable, air is smooth. Too large to open, strong in summer sun, easy to make people tired; large heat loss in winter, increase heating fee
