If the glass were kept hot enough, it would flow over the molten tin until the top surface was also flat, horizontal and perfectly parallel to the bottom surface.
如果玻璃保持足够的温度，它就会在熔化的锡中流动，直到顶部表面也变得平整、水平，与底部表面完全平行。
The partial cavity consists of two horizontal adiabatic surfaces, a vertical hot surface and a cold surface with varied opening.
方形空腔由两个水平绝热壁、一个竖直加热壁而另一个竖直壁为冷壁但具有变化的开口度组成。
