摘　　要：简述了用变角辐射计测量光源的总辐射通量及总光谱辐射通量的原理和方法。介绍了变角辐射计的组成和特点，并使用该装置测量了3种光源的辐射通量，测量结果的不确定度为1.6%~3.6%（k=2）。由辐射通量计算得到的光通量与光度法测得的光通量的偏差小于0.9%，在不确定度范围之内。The theory and method of measuring total radiant flux and total spectral radiant flux is described. The components and character of a goniospectroradiometer had been introduced. Three kind of light sources have been measured, the measurement uncertainty is 1.6% -3.6% （k = 2）. Luminous flux calculated by the spectra radiant flux comparison with NIM＇s photometric based luminous flux scale shows that agreement is within 0.9%, well within the combined measurement uncertainty.
