【摘要】 血蜜蜡是2015年底我国市场上出现的琥珀新品种,具有少见的颜色和独特的根须状包体(俗称"根系纹")。根须状包体的成因目前尚无定论,但其形态与绝缘材料经电子束辐照引发击穿放电产生的利希滕贝格图形有很高的相似性。琥珀和柯巴树脂作为绝缘材料经电子束辐照能否生成利希滕贝格图形尚未有报道。为此笔者收集了琥珀和柯巴树脂样品进行了电子束辐照实验。实验结果表明,在适当的工艺条件下,琥珀和柯巴树脂样品均可以通过电子束辐照技术产生根须状包体。辐照生成的根须状包体实则是琥珀和柯巴树脂样品被击穿放电形成的伴有应力裂纹的树枝状通道,即利希滕贝格图形。样品经辐照生成的根须状包体与血蜜蜡样品中的根须状包体在形态特征上基本相同。更多还原

【Abstract】 Blood Mila is a new kind of amber that has appeared on the market since last year,which has uncommon color and unique root-like inclusions(known as root-like patterns).There has been no definite conclusion about the genesis of such root-like inclusions so far.The root-like inclusions are extremely similar in morphology to the Lichtenberg figures in which the insulator initiates the generation of breakdown discharges through irradiation by electron beam technology.As insulators,whether amber and copal can generate Lichtenberg figures by the electron beam irradiation technology has not been reported yet.Therefore,the authors collected some amber and copal samples to perform electron beam irradiation test.The results show that the root-like inclusions can be generated in both amber and copal samples by the electron beam irradiation technology under appropriate process conditions.The root-like inclusions generated by irradiation are the dendritic channels with stress-related cracks generated by breakdown discharge in amber and copal samples,also named Lichtenberg figures.The root-like inclusions generated in tested samples by irradiation are almost the same in morphology as those in Blood Mila samples.更多还原
