摘要
根据低纬子午环绝对测定的要求，在原来的测微器方案〔１〕的基础上，针对斜狭缝用于卯酉方向测定天顶距时所存在的问题，对原来的视栅形式作了进一步改进。本文对改进后的视栅形式及观测原理加以说明，并讨论了视栅的狭缝倾斜对测定量的影响及测定狭缝倾斜的方法。
According to the demand of the absolute measurement by the Low-latitude meridian circle, for problems of the measurement of the zenith distance in the direction of the prime vertical using the slant silts, the previous grating form is improved based on the former micrometer scheme. The new grating form and the measurement principle are introduced in the paper. The influence of the degree of the slant of slits for the measurements and the method of determination of the tilt of slits are also discussed.
