如果发生地震,怎样减少建筑物的损害呢?这里有一种非常实用的方法介绍给大家。先让我们做一个小实验吧,剪裁四片长方形硬纸板(图1),然后分别等距离钉在一块长方形木板上,再分别用两块小木板将四片硬纸板连接成两个建筑模型(图2),将其中一个模型顶部放上一盘水(水不要加满)。模型做好后开始作实验,
If there is an earthquake, how can we reduce the damage to the building? Here is a very practical way to introduce it to everyone. Let us do a small experiment first, cut out four rectangular cardboard pieces (Figure 1), and then place them on a rectangular wooden board at equal distances. Then use two small boards to connect the four pieces of cardboard into two building models ( Fig. 2) Put a plate of water on top of one of the models (the water should not fill up). After the model is done, start experimenting.
