摘　　要：详细介绍了一种光电式自动日照计的原理和结构,并对基于该原理和结构的3种自动日照计开展了比对试验,试验以直接辐射表为参考标准,在不区分天气条件下分析3种自动日照计的月总量日照时数相对误差都在5%以内,在区分天气条件时,除阴雨天月总量日照时数相对误差较大外,多云天气条件下在5%左右,晴天在2%以内,证实了国产自动日照计能够满足目前日照观测自动化和准确性的要求。The principle and structure of a photoelectric automatic sunshine recorder is introduced in detail in the paper. And the comparison test on three kinds of sunshine recorder is carried out. In the test a pyrheliometer is served as the reference. In non-distinguishing weather condition, the relative measurement errors for three kinds of automatic sunshine recorder are all in the range of 5% by analyzed respectively. And in distinguishing weather con- dition, the relative measurement errors are much bigger in rainy days, and about 5% in cloudy days and in the range of 2% in sunny days. The results verify that the China-made automatic sunshine recorder can satisfy the auto- mation and accuracy requirements of the surface meteorological observation.
