And use relative fitting error to measure statistical data non - uniform error ; then introduce the method systematically of using the fuzzy comprehensive evaluation method to carry on the overall superior test of the government statistical data quality. includes the establishment of step level appraisal target system, target weight determination, calculates the factor weight in various levels, uniform test of judgment matrix, and built up the final fuzzy comprehensive evaluation model of the government statistical data quality according to the above - mentioned standard ; finally selects the partial main social economy total quantity target from chinese statistics yearbook 2003 to carry on the real diagnosis analysis : ( 1 ) confirm these social economy total quantity targets using the description statistics and the k - s inspection method to obey the lognormal normal distribution. ( 2 ) according to the two levels of inspection methods which this article proposed to carry on accuracy and the overall superior test for these social economy total quantity targets
本文首先從統計數據及質量的涵義出發，全面系統的介紹了統計數據質量的概念;其次，從研究統計數據的分佈規律入手，對統計數據準確性檢驗問題進行了探討，利用對數正態分佈檢驗對反映研究對象規模大小的統計數據的質量及異常數據進行定量檢查和識別，並利用相對擬合誤差計量統計數據的非一致性誤差;接著系統介紹了利用模糊綜合評價方法對政府統計數據質量進行整體優度檢驗的思路，具體包括建立遞階層次的評價指標體系，指標權重的確定，計算各層次中因素的權重，判斷矩陣的一致性檢驗，並根據上述標準建立了最終的政府統計數據質量模糊綜合評價模型;然後通過從2003年中國統計年鑒資料中選取部分主要的社會經濟總量指標進行實證分析: （ 1 ）利用描述統計和k - s檢驗法來驗證這些社會經濟總量指標服從對數正態分佈的規律; （ 2 ）按照本文提出的二級檢驗法來對這些社會經濟總量指標進行準確性和整體優度檢驗，從而達到綜合評價政府統計數據質量的目的;最後對這種二級檢驗法的優點和不足進行小結，提出今後應該努力改進的方向。 -
The sensitivity analysis and discussion of pose measurement error caused by the measurement errors of coordinate measuring machine and by the coordinate errors of three standard spheres on the base platform has been done in detail. the pose measurement error formulas as function of the measurement errors of coordinate measuring machine and the coordinate errors of three standard spheres have been deduced and it has been discovered that larger relative diatances among the three standard shpheres will efficiently minimize the influence of the measurement error of coordinate measuring
推導出了三坐標測量機的測量誤差、固定平臺上三個標準球的位置誤差對位姿測量誤差的函數，發現只要適當地增大固定平臺上三個標準球之間的相對距離，就能夠有效地降低三坐標測量機的測量誤差和固定平臺上三個標準球的位置誤差對位姿測量的影響，從而提高了位姿測量的準確性。
