But the traditional discipline of evaluating accuracy has been used in the geodesy. Many papers on uncertainty theory are still using the precision of theoretical concepts to explain the theory of uncertainty, resulting the difficulties in extending uncertainty theory. In this paper, we contrast and analyse the traditional theory of measurement with philosophical concept of uncertainty theory, considering with specific practice. We compare the theory of measurement uncertainty with the accuracy theory in geodesy from the basis concepts, the epistemology and the methodology . It sums up the essential difference between the category thinking and the existence thinking for the first time. It is been clarified that the theory of measurement uncertainty is a more scientific and strict discipline than the traditional theory of evaluating accuracy, and uncertainty evaluation should be promoted in the geodesy. Key words: measurement; uncertainty; geodesy; precision; error. 引言 测量不确定度理论于1963年由美国国家标准局（NBS）的Eisenhart首先提出，在历时了30余年的国际学术界讨论后，成为当前国际上表示测量结果及其不确定度的通
