| Abstract: | Authors analyzed the disadvantages of two data processing methods of permutation intercomparsion and a more perfect data processing derived by the least squares method.The new algorithm makes the influence of measuring errors on two intercomparative workpieces same,the calculated results are unique and the residual squariance is minimum.The cause of the linear harmonic system error appeared in the results of permutation intercomparsion method is first described in theory.A reducing and elimination method for this system error is proposed and it has been demonstrated by experiment. |
