在毛主席革命路线指引下,为实现敬爱的周总理在四届人大提出的“在二十世纪末实现四个现代化”的宏伟目标,物理教研组同志以大庆为榜样,坚持独立自主,自力更生的方针,抵制“四人邦”的干扰和破坏,以革命加拼命,大干了还要大干的革命精神,自一九七五年八月到十二月,只用了四个月左右的时间,自行设计并安装成功第一台集成电路数字式钢弦测周仪,经过一年来,在工矿多次实测证明电路性能良好,该仪器先后在陕西省高等学校教育革命成果展览会及全省农业学大寨展览会上展出。一九七七年四月开始应用在量测地应力予报地震的科研项目中,并在全国地震战线学大庆会议地震仪器展览会上展出。该类仪器目前只有几个厂少量生产,并且仅是晶体管式的,PSJ—3型是应用了第三代电子器件——集成电路,从而进一步提高了仪器工作的可靠性,减轻了重量,减小的体积和功耗,更便于野外作业。 Guided by Chairman Mao’s revolutionary line, in order to realize the grand goal set forth by the beloved Premier Zhou in the Fourth National People’s Congress, “realize the four modernizations by the end of the twentieth century,” the comrades of the Physics Teaching and Research Group took Daqing as an example and adhered to the principle of independence and self-reliance , Resisted the interference and sabotage of the “gang of four,” added even more force to the revolution and made even greater efforts to carry out the revolutionary spirit. From August to December 1975, it only took about four months Of the time, to design and install the first successful digital integrated circuit digital steel measuring week instrument, after a year, many times in the mining industry to prove that the circuit performance is good, the instrument successively in Shaanxi Province higher education revolution results exhibition Provincial Agricultural Exhibition Dazhai exhibition. In April 1977, it began to be used in scientific research projects measuring earthquakes to measure earthquakes and exhibited at the Seismological Equipment Exhibition of the National Seismological Battle Line Science Daqing Conference. At present, only a few plants of this type are produced in small quantities, and they are only transistor-type. PSJ-3 is the third generation electronic device integrated circuit, which further improves the reliability of the instrument, reduces the weight and reduces Small size and power consumption, more convenient for fieldwork.
