1984年11月9日邮电部召开技术鉴定全,通过了北京邮电学院副教授彭道儒同志发明的DGB—823电接触固体薄膜保护剂技术鉴定,批准转入批量生产。经检索国内文献并同国外样品对比试验,证明其性能超过同类产品,达到了先进水平。DGB—823对电接触元件有极好的保护作用,因而,将DGB—823推广应用在航天、航空、航海及民品上,对提高产品可靠性和经济效益有重大意义。这里简要介绍如下:
November 9, 1984 Ministry of Posts and Telecommunications held technical appraisal, adopted by Beijing University of Posts and Telecommunications associate professor Peng Dao-ru DGB-823 electrical contact solid film protective agent technical appraisal, approved the transfer to mass production. After the retrieval of domestic literature and comparative tests with foreign samples to prove its performance over similar products, reached the advanced level. DGB-823 has excellent protection for electrical contact elements. Therefore, it is of great significance to promote the reliability and economic benefits of DGB-823 in space, aviation, navigation and civil products. Here is a brief introduction as follows:
