查询词典 optical

The calculations show that the principle formula error have small influence on the aberrations of an optical system, but as the stundard measurement of a refractive index, so great principle formula error is not allowable.

这样，虽然仪器本身具有高精度的测试性能，但原理公式误差大大地超过了仪器的测试精度，导致错误的测试结果。因此指出原理公式误差，评价其大小，重新推导测量绝对
