摘　　要：一、引言 折射率大于2.1的微珠为高折射率玻璃微珠。它作为微型球体透镜用于交通标志而称为回归反射微珠,是我国发展高速公路和改善交通运输所急需的高技术新材料。近几年来,国内少数厂商开始试制这种新材料。该材料在原则上必须要求微珠的折射率高达2.2以上,并且在几何学上要求微珠是一颗颗真正的球体,其个体的圆度误差宜在1％以下,其尺寸分布谱带尽可能属于窄带分布,峰形尖锐。因此,微珠群体的形状因素。A high refractive solid medium has been used to measure refractive index and diameter of imported microbeads by optical interference microscopy (interphako). Statistic distributions of refractive index and diameter (especially in different size range) are obtained. The index shows a log. normal probability distribution. The size approaches a normal probability distribution. In addition, the comparison between imported and home-made microbeads has been also made in their distributions.
