Abstract Systematic error can not be ignored in study of crust deformation and high precision data processing. thus its influence should be weakened as far as possible In this paper．the problem on adjustment compensation of systematic error is discussed and some simple and practlcal methods for testing E(△)=0 according to residual error after diustment are brought up. The variance estimation of systematic error for which concepts of confidence region in probability and method of region estimation are used，is focused on．In adjustment compensation of systematic error．method with system parameter added in is discussed and model with system weigtlt added in is given It can be concluded that，for weakening influence of systematic error，the method whh both the system parameter and system weight is m ore effective
Key words ：
systematic error
variance estimation
