我们遵照伟大领袖毛主席关于“打破洋框框,走自己工业发展道路”的教导,发扬了“自力更生”、“艰苦奋斗”的革命精神,开展了群众性的技术革新活动。我们用两个报废风缸和一些废旧材料,试制成功了一台14公斤/厘米~2客车暖汽软管水压试验机(图1),解决了我们的生产关鍵。 In accordance with the teachings of Chairman Mao, the great leader, on “breaking the framework of the world and taking the road of industrial development,” we have carried forward the revolutionary spirit of “self-reliance,” and “arduous struggle,” and carried out mass-based technological innovations. We used two scrapped air cylinders and some scrap materials to successfully manufacture a 14kg / cm ~ 2 passenger car hydraulic hose hydraulic pressure testing machine (Figure 1), which solved the key of our production.
