摘要
本文提出了在费氏台测量过程中,当遇到一些特殊情况,如光轴面与薄片平面夹角较小的条件下,如何测定2V的方法。1是用测定公式计算;2是用诺模图解方法,最后进行了误差讨论并提出如何减少误差的具体要求。
In the measurement of 2V by means of Fedorov stage on the condition of small angle intersection of optic plane and thin section Plane,two methods are Put forword:(1)calculation formula; (2) nomograph. Finally,theerrors are discussed and countermeasures raised accordingly.
