| Abstract: | In this paper, detailed analysis of measuring the uncertainty sources of small angle tester, the corresponding standard uncertainty components and degree of freedom is given. On the basis, the syn- thetic uncertainty and effective degree of freedom is proposed. The expanded uncertainty is put forward when the confidence probability reaches 99%, which makes the dissemination more reliable. |
