摘　　要：通过对4种型号数字水准仪和Ni002A光学水准仪的同桩比测表明:1)数字水准仪相对Ni002A光学水准仪没有明显的系统测量偏差;2)条形码标尺米长改正数f值在实际水准观测结果中必须进行修正;3)SDL1X、DiNi03、DNA03型号数字水准仪可用于一等水准测量,DL101C数字水准仪只能用于二等水准测量。Comparison of the data measured by four kinds of digital levels, and a optical level Ni002A, based on same piles shows that：1 ）There is not obvious systematic measurement deviation in the digital levels relative to the optical level Ni002A ;2）Bar code level rod＇s length correction f value must be corrected in the practical leveling measurement ;3 ）SDL1X,DiNi03 and DNA03 style of levels can be used in the one-grade-leveling measurement, and DL101C can be used in the two-grade-leveling measurement only.
