1977年9月7日至8日由冶金部和铁道部共同主持,在北京召开了铁路小站信号设备试用硅太阳能电池座谈会,除两部所属十多单位外,还有中国科学院科技办、四机部、国家地震局、中央气象局等共40多位同志参加了会议,与会同志参观了冶金部上海901厂、洛阳740厂和铁道部电化工程局共同协作为高原铁路试制的200余瓦硅太阳能电池方阵,听取了上海901厂和电化工程局关于试制以及在北京试验情
From September 7th to 8th, 1977, co-chaired by the Ministry of Metallurgy and the Ministry of Railways, a silicon solar cell seminar was held in Beijing for trials of signalling equipment for railway stations. In addition to the two more than ten units, there was the Science and Technology Office of the Chinese Academy of Sciences. More than 40 comrades including the Fourth Division, the State Seismological Bureau, and the Central Weather Bureau attended the meeting. Comrades visited the Shanghai 901 Plant of the Ministry of Metallurgy, the Luoyang 740 Factory, and the Ministry of Railways Electrochemical Engineering Bureau jointly collaborated to produce more than 200 watts of plateau railways. The silicon solar cell square array listened to the Shanghai 901 plant and the Electrochemical Engineering Bureau on the trial production and the test situation in Beijing.
