Fig. A): Let’s examine the behavior of particles in a closed container.
(图A):让我们来观察一下粒子在封闭容器中的行为。
(Fig. B): The more particles we squeeze into the container, the testier they will become, especially if the container happens to be a rush-hour downtown local at 86th and Lex.
(图B):如果我们把更多的粒子挤入容器中,它们将变得易爆,特别是当这个容器正好是高峰期的下城86街和莱克星顿大道路口的那个地铁站。
(Fig. C): Usually the particles will distribute evenly, unless there is a weird-looking puddle on the floor.
(图c):通常粒子会分布均匀,除非地板上有一滩奇怪的的不明液体。
