摘　　要：在同一观测场内,用同一厂家生产的4支铂电阻温度传感器,同时测量1个百叶箱和3个防辐射罩内的温度,以百叶箱内的温度作为参考标准,进行比对试验。结果表明:其中两种防辐射罩在白天的辐射误差较大,不能满足业务使用要求;有一种防辐射罩的辐射误差较小,基本符合业务使用要求。In the same observation field, this experiment measures the temperature in thermometer screen and three radiation protection cover with four temperature sensors of platinum resistor which are manufactured by the same manufacturer. Taking the temperature of thermometer as a reference standard,the author compares the data of these three platinum sensors. The results show that the radiation error of two radiation protection covers is greater during the day that can not meet the operational requirements. The radiation error of one radiation protection cover is smaller than others that basically meets the requirements.
