1992年11月26日在五院五一一所召开了“航天用发光强度一级标准装置”鉴定会。专家们听取了研制报告、测试报告和使用意见报告,查看了标准装置和试验室。鉴定委员会认为:由五支BDQ8型灯组成的标准灯组发光强度年变化率小于0.7％,中性减光片透过比测量精度为±0.3％,整套装置测量不确定度小于1％,原理正确,方 On November 26, 1992, a conference entitled “First-class Light Intensity Standard Device for Aerospace Use” was held in May 21, The experts listened to the research report, test report and opinion report, and looked at the standard equipment and laboratory. Accreditation Committee believes that: the standard lamp group consisting of five BDQ8 lamp luminous intensity annual change rate of less than 0.7%, the neutral absorption of light transmittance than the measurement accuracy of ± 0.3%, the whole device measurement uncertainty of less than 1%, the principle Correct, square
