| Abstract: | Summarizing the improvement of the observational result precision of short-range leveling at Qingyuan seismic station in 1985,some successful measures on how to improve the observational result precision of stations short-range leveling are given.Main of the measures are:to select the optimum line length of sight,to widen the line of sight,to raise the line of sight,to reduce the influence of astronomical refraction,to remake the condition of the instrument station,to fix the surveying time and the surveyor and to define the period of observation time. |
