江南丘陵山区,北风阵阵,夹着小雨。夜深人静时,天又黑又冷。某市化工厂合成氨车间,灯光明亮,机器轰鸣,一派热气腾腾的生产情景。离次日零点只差3分钟,负责送气的罗茨风机岗位忽然响起一阵长铃,时间长达五、六秒钟。这是工厂规定的紧急停车信号,操作工人犹豫了一下,正准备与后工段联系,这时又是一阵更加急促的长铃声。铃声就是命令!紧急停车己刻不容缓。 Southern hills and mountains, northerly bursts of light, sandwiched between light rain. The sky was dark and cold at night. A city chemical plant ammonia workshop, bright lights, the machine roar, a steaming production scene. Zero point from the next day only 3 minutes, responsible for sending air Roots blower suddenly sounded a long bell, for up to five or six seconds. This is the factory emergency stop signal, the operator hesitated a moment, is preparing to contact with the work section, then a burst of more rapid long bells. Ringtones is the order! Emergency stop is urgent.
