试论偏翼镞的用途——史前人类是否认知光的折射?

On the Use of the Asymmetric Arrowhead:If Humans Had Understood the Idea of Light Refraction in Prehistory

本文初步搜集了我国各时期遗址中出土的偏翼镞,并根据偏翼镞多与鱼镖、鱼钩、网坠等捕鱼工具共出于同一遗址或遗迹的现象,以及光的折射的原理,提出偏翼镞用于渔射的假设。最后通过模拟实验对假设加以检验,结果表明,偏翼镞飞行后的落点较对称形镞偏下,有可能专门用于渔射。这说明在史前时期,人类已经对光折射的现象有了一定的认识。

This paper describes many asymmetric and puts forward a hypothesis that the asymmetric arrowheads from a number of ancient sites, arrowhead was used for shooting fish, which is based on the fact that many asymmetric arrowheads coexist with other fishing tools at the same sites. Experimental results show that the flight path of the asymmetric arrowhead is lower than the symmetrical arrowhead, which suggests that the asymmetric arrowhead was possibly used for shooting fish, and thus human understood the concept of light refraction in prehistory.
