| 摘 要： | 针对全组合测量的数据，根据最小二乘法原理，提出了一种特殊的多套测试系统精度比对实验中标准差的最小二乘平差处理方法，当比对套数ｍ＞３时，利用此方法可分解开究竟哪一台仪器（或哪一套测试系统）的标准差最小，哪一台其次，从而评定参与比对各仪器精度的优劣，并以五套测速比对系统为例进行分析、论证。

| Abstract: | A least square adjustment of standard deviations is presented,which can be used in the accuracy of several testing systems.It can judge which onehas the least standard deviation,i.e.the highest accuracy as well as the accuracy ofevery compared devices or systems when the number of the devices are greater thanthree.As an example,the data measured for five systems for velocity measurementof bullets is analyzed and demonstrated. |
