| Abstract: | The primary and direct causes of the refraction coefficient variation in lowest tropsphere are analysed based on the fundamental definition of the atmospheric vertical refraction. Five characteristics with variation of the refraction coefficient are indicated,i, e. ,characteristics of time,climate,height,soil and mean value,some viewpoints in application of surveving are put forward based upon the results in this paper. |
