现在人们使用的简易气体打火机,装丁烷液体的塑料容器一般都被塑料片隔成两部分,而这两部分下端又是连通的,有些学生将打火机倒过来,无论怎样摆动,两容器中液面都很难相平.对此甚感迷惑.要解释清楚这个问题,首先要弄明白该装置究竟是不是“连通器”.在人教版新教材初中物理第一册P123有“上端开口,下部相连通的容器叫连通器”这样叙述比原教材中“底部互相连通的容器叫连通器”更为科学、准确,这里
Now people use simple gas lighters, plastic containers filled with butane liquid are generally divided into two parts by plastic sheet, and the lower part of the two parts are connected, some students will reverse the lighter, no matter how the swing, two containers of liquid Face is very difficult to be equal. This is very confused. To explain this issue, we must first understand whether the device is a “connector”. In the new textbook PEP junior middle school physical book P123 has The upper end is open, and the lower part is connected to a container called a “connector”. This description is more scientific and accurate than the “connected container at the bottom” of the original textbook.
