根据工农业生产的发展和国防建设的需要,我校半导体厂在1974年接受了研制NG04型集成运算放大器的任务.我们物理系半导体专业工农兵学员结合这一具体战斗任务进行了毕业实践.由于工人师傅和工农兵学员的共同努力,经过四个月的时间,试制成功了通用型高增益的NG04集成运算放大器.? According to the development of industrial and agricultural production and the need of national defense construction, our school’s semiconductor factory accepted the task of developing NG04 type integrated operational amplifier in 1974. Our physics, semiconductor, laborer and peasant trainees engaged in graduation practice in accordance with this specific combat task. Workers master and workers and peasants and soldiers of the joint efforts, after four months, the trial success of the common high-gain NG04 integrated operational amplifier.
