石片研究

石片是石制品的重要组成部分, 其分类须遵循逻辑划分, 研究应规范化、系统化和简单化。按照台面和背面特征划分石片类型越来越趋向共识。石片台面由其背面缘和破裂面缘构成,是由直线、折线和弧线相互组成的几何图形, 它的形状反映剥片思维的逻辑构想。依据单疤、双疤、多疤组合和单向、双向、多向组合观察石片背面有助于剥片流程的分析。从背面观测石片的长度和划分左右较为合理, 参照人的手掌和手指判定石片大小和依据黄金分割律确认石片的形态应该是较有理的选择。石片除了制作食物外, 更多功效的猜想也值得考虑, 如敬奉首领、示爱异性、切割头发胡须、挠痒痒和清理排泄物等。

A study of flakes

The flake, as one of the important components of stone artifact assemblage, is an absolutely necessary key to resolve the manufacture techniques on the making stone artifacts by early hominins. It is also a direct evidence of material object used to interpret the Paleolithic culture and the adaptive behavior of early human in the Old Stone Age. However, the observation and study of the flakes should be based on systematization, standardization, and simplification. Classifying stone flakes must adhere to the principle of logic differentiation and all the methodologies of studying flakes should be understandable and compatible each other.
It should be best for flakes to be classified based on characteristics of its platform and dorsal surface. The shape of the flake platform suggests the logic configuration of flaking anamnesis, and it is made up of the edges on butt, that is the geometry figure combined from beeline, flex line and arc line. The flake scar on the dorsal surface could provide a probability to explain the flake work process and it should be observed in the light of the scar quantity (single, double, many) and direction (single, double, many). It would be well-founded for the length and right- and-left sides to be observed on the dorsal surface. It is best for the flake size to be classified based on the human palm and finger in order for the flake form to be confirmed by the golden section of index of breadth/length and thickness/breadth.
The purpose of flake production and repair include hunting and making foods, as well as giving to leaders or friends as gifts, haircutting and shaving beards, scratching itch, cleaning up excreta and other behaviors.
