摘　　要：根据ＷＭＯ对全波辐射表规定的性能指标，对国产净全辐射表进行了逐项测试，着重研究辐照度大小、环境温度、光线的不同入射角度、零点漂移、罩形变化等对仪器性能的影响。再一次验证了仪器的全波和长波灵敏度之间存在着差异，阐述了测试前对半球罩充气的必要性。结果表明，国产净全辐射表的性能并不比进口仪器差。According to the WMO specifications for pyrradiometer,the performance of net pyrradiometer made in China have been tested.The influences of irradiance,ambient temperature,incoming direction of beam and zero drift as well as hemispheric dome of polyethylene on net pyrradiometer are mainly studied during the tests.The necessity to fill air for hemispheric dome before measurment is emphasized.From the series of test,the large difference of the sensitivities between the allwave and longwave of the instrument is once verified.The results show that the performance of net pyrradiometers made in China are almost as same as the imported ones.
