研究早已注意到石包大小和还原强度对岩屑组合组成的影响，特别是以片状粒度分布的形式。然而，在考古学背景下，如果不控制这两个变量中的一个变量的变化，仍然很难客观地区分这两个因素的影响。在这里，我们报道了一项实验研究，旨在检验原始石块大小和还原强度对岩心还原过程中产生的石片碎屑的粒度分布没有影响的零假设。结果表明，原始结石大小的影响在统计学上是显著的，但还原强度并不影响，尽管前者的影响很小，被认为是微不足道的。在回顾旧石器时代中期遗址的考古组合序列时，与实验数据相比，所有这些都显示出过多的小尺寸材料。当较小规模类别的异常高频率出现时，攻丝过程显然是原因所在。
Studies have long noted the influence of stone package size and reduction intensity on lithic assemblage composition, particularly in the form of flake size distributions. However, it remains difficult to distinguish objectively the effect of either factor in archaeological contexts without controlling for the variation in one of the two variables. Here we report on an experimental study designed to test the null hypotheses that original stone size and reduction intensity have no impact on the size distribution of lithic flake debris produced during core reduction. Results indicate statistically significant influence from original stone size but not reduction intensity, although the effects from the former are low enough to be considered trivial. In reviewing a sequence of archaeological assemblages from a Middle Paleolithic site, all exhibit an excess of smallsized materials in comparison to the experimental data. When exceptionally high frequencies of the smaller size classes occur, taphonomic processes are clearly responsible.
