摘　　要：本文主要描述了工作级标准直接辐射表的设计原理及结构,在热电堆和感应面组成的平面感应件上,利用加半球反射罩的人工黑体和多层光栏消除杂散光技术,通过对仪器结构的优化设计,确定最佳尺寸,研制出了TBS-2-B型工作级标准直接辐射表,其不确定度为1%,达到世界气象组织(WMO)仪器和观测方法委员会(CIMO)有关工作标准直接辐射表的要求。经过多年与我国标准直接辐射表(腔体绝对辐射表)进行比对,仪器性能非常稳定,并作为工作级标准直接辐射表在气象辐射仪器计量检定业务中应用。This paper presents the principle, basic configuration of working standard pyrheliometer. The technologies of adding hemispherical mirror black body and using multi-layer diaphragm to suppress stray light were applied on the sensor which is made up of thermopile and planar sensor. By the optimal design of the instrument structure, the best sizes are determined. The TBS-2-B working standard pyrheliometer has been developed with the uncertainty of 1% and can satisfy the requirement of Commission for Instruments and Methods of Observation （CIMO） in World Mete- orological Organization （WMO）. Comparisons have been made with National Standard Pyrheliometer（HF cavity pyrheliometer）, the agreement is satisfactory. The TBS-2-B pyrheliometer have been used in the calibration of pyrheliometers.
