摘　　要：对专用测具空间尺寸的测量方法进行了分析研究,利用精密平台配备数显测高仪、杠杆千分表与标准滚(量)棒,采用双杠杆千分表交叉换位的方法对空间尺寸进行检测。测量方法比较和测量不确定度评定的结果表明,本文方法解决了以往使用单只千分表检测空间尺寸效率、精度较低的问题。A method for measuring a specific measurement of spatial dimensions was analyzed using sophisticated platform with digital altimeter, lever dial gauge and standard roll （amount）rods, and a coordinated trasposition of double lever dial gauge approach was adopted to detectspatial dimensions, Comparison of the results of measurement and evaluation of the measurement uncertainty show that this method can solve theow efficiency and accurancy problems of a single micrometer for spatial dimensions detection,
