margin: 0px 0px 26px; text-align: justify; word-break: break-all;">三维扫描显示，鹅卵石上的孔是用燧石手钻从两侧钻到一半的。与现代钻头不同的是，它留下了一个狭窄而扭曲的锥形形状。这些孔的直径为3到4厘米，通常穿过鹅卵石的重心。</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">“从两侧钻孔有助于平衡石头，使其旋转更稳定。一些部分穿孔的石头有偏离中心的孔，这表明它们可能是错误的，就被丢弃了。”Yashuv说。</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">研究人员一开始觉得，这些平均重9克的石头太丑了——不可能是装饰的珠子，也太轻、太脆弱了——不可能用作捕鱼砝码。它们的大小、形状和孔周围的平衡使研究人员确信这些石制工具是纺轮。</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">为了验证假设，研究人员用遗址附近的鹅卵石和燧石制作了复制品。然后，他们请传统手工艺人Yonit Kristal试着纺亚麻。</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">Yashuv说：“真的很惊讶它们能运转起来，因为它们并不是完美的圆形。但实际上，只需要将孔定位在物品的中心，就能平衡并运转了。”</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">Yashuv表示，如果这些穿孔鹅卵石真的是轮子，那它们就是最古老的纺轮。这一发现表明，在大约5500年前发明制陶轮和推车轮之前，人们早已试验旋转技术几千年了，而纺轮可能有助于这些发明。</p> <p style=";; margin: 0px 0px 26px; text-align: justify; word-break: break-all;">然而，法国蔚蓝海岸大学的Carole Cheval却认为，这些穿孔鹅卵石更像陀螺，而不是轮子。“这项研究缺乏揭示使用痕迹的微观数据，因为随着时间的推移，纱线会在石头上留下痕迹。”Yashuv回应称，痕量分析“超出了当前研究的范围”。</p> <p class="lastPadding" style=";; margin: 0px 0px 26px;
