摘　　要：介绍了按国家平面角检定系统规定的光学角规系列标准计量器具的等级及传递方法，介绍了标定光学角规偏向角ＰＪ—２型仪器的新改进，首次提出标准光学角规组合原理和应用，并且给出组合应用的扩展不确定度，列举了组合标准光学角规补偿法在光学材料高精度直接测量色散中的应用和在Ｔ３经纬仪示值误差检定中的应用。The grade and transfer method of serial optical angle gauges, which standard measuring instruments setted by national plane angle verification system, are discussesed. The improvement of PJ 2 instrument that calibrates the gauges is also proposed. The combination principle and application of standard optical gauges is presented firstly. Also, the extended uncertainty of the combination application is given. Application of combination standard optical angle gauges compensation method measured in high accuracy dispersion of optical material and testing indication errors of the theodolite is enumerated.
