| Abstract: | In order to reduce uncertainty of primitive data using pitch to measure straightness and flatness, this paper adopts the theory of least square adjustment to settle principle problems of measurement adjustment of straightness. In addition it compared and analyzed the project of the measurement adjustment of flatness. We testify the availability of adjustment through a large number of experiments. It is of practical significance to draw up the criterion of measuring the straightness and enhace the inspection accuracy in engineering. |
