摘　　要：采用统计假设检验和正态性检验的方法,对潍坊市大地水准面精化成果的精度、是否存在系统误差等方面进行分析讨论,得出了潍坊地区的大地水准面精化成果可以替代四等水准测量成果的结论,在降低劳动强度,提高作业效率方面具有一定的意义。This paper analyzes and discusses the precision and systematic error of geoid refinement results in Weifang City by using the methods of statistical hypothesis test and normal test in mathematical statistics,and concludes that the refined geoid results in Weifang can replace the fourth-class leveling results,which can reduce labor intensity and improve operation efficiency.

关 键 词：大地水准面精化 统计假设检验 正态性检验 GNSS
