Abstract


At present, whether from the national standard or the Ministry of Construction Standardization Department or the State General Administration of Sport sports facilities and standards of the office or the State General Administration of Quality Supervision, Inspection Measurement Department have yet to be established competitive playing field testing and compliance standards and will never test venue The results were evaluated purely measurement results are given. Thesis is based on the distance Shunyi Olympic Rowing-Canoeing Park race-lines, The introduction of measurement adjustment theory, is proposed to amend the number of vectors and the observed values of the functional relationship between the error vector is obtained observables of the most reliable results and test the accuracy of measurement results. Because even if the systematic errors that have been identified in the amendments, the measurement results measured value is still only an estimate of value, because there is not only measured in the random factors will result in uncertainty, but does not completely factor correction systems are also there is uncertainty.By measuring the adjustment process the results including the measurement and characterization of the measurement results of this measurement uncertainty standard deviation. Survey Adjustment Act is essentially equivalent to the random measurement error of less effective, ranging from the right of the measurement error of the non-deterministic system, but for the middle of the right measurement error of the non-deterministic system does not to eliminate or weaken the role of play. Therefore, the measurement results obtained after adjustment standard deviation, but characterized by a random effect due to measurement uncertainty, in order to complete characterization of measurement uncertainty, but also need to consider the systemic effects caused by non-uncertainty and to be synthesized.Second, the above-mentioned theory, only with a clear that the random error (adjusted results) is due to measurement of the random factors or effect arising from the true value is measured relative to the deviation, such random factors or effect, will result in measurement results when repeated measurements the value of dispersion. Measurement uncertainty can be assessed to determine the uncertainty components (equipment, environment, repeatability, etc.). Is calculated through a large number of data can validate the accuracy of test results of the report.
