高中物理课本提到的用橄榄油制取大球形液滴的实验,可用材料易得,制作简便的“萘液法”来代替。具体操作如下。1.取—50毫升小烧怀,放入适量萘(或卫生球十余粒),置于石棉网上,用酒精灯加热熔解(见图1),萘球全部熔完只需数分钟。 The high school physics textbook mentioned the experiment of making large spherical droplets from olive oil. The available materials can be easily obtained and a simple “naphthalene solution” can be used instead. The specific operation is as follows. 1. Take - 50 ml small boiled, add the appropriate amount of naphthalene (or more than ten tablets of the health ball), placed on the asbestos network, heated with an alcohol lamp melting (see Figure 1), all the naphthalene balls melted only a few minutes.
