摘　　要：本文研究了日月潮汐对水准高差的影响 ,导出了水准高差的日月潮汐改正公式 ,从而验证了现行水准测量规范引用的公式 ,并发现其存在的个别错误 。The paper deals with luni-solar tidal effects on height differences measured by precise leveling,presents the correction formulas of leveling height differences for luni-solar tides,thereby verifying the formulas quoted by the existing specifications of precise leveling,and shows few mistakes committed there. The expressions for Sun and Moon's hour angle and declination as needed to compute the tidal corrections are also given in the paper.

关 键 词：日月潮汐 水准高差 日月黄道坐标
