瑞典化学家诺贝尔发明了多种炸药,但都不尽人意。于是,研制一种既安全又高效的新炸药,成了他追求的目标。1875年的一天,他在实验室工作时,不小心划破了手指,一时流血不止,束手无措。这时,他随手贴上一块名叫硝棉胶的创伤膏。夜里,实验的难题困扰着他,手指的疼痛折磨者他,他一整夜没合眼。好容易熬到早晨,他感觉手指的疼痛减轻了,便拿开硝 Swedish chemist Nobel invented a variety of explosives, but they are not satisfactory. Therefore, the development of a safe and efficient new explosives, has become his goal. One day in 1875, when he was working in the laboratory, accidentally scratched his fingers, sometimes bleed, at a loss. At this time, he readily affixed a piece of trauma cream called cotton glue. Night, the experimental problems plagued him, the pain of the fingers torture him, he did not fit all night. So easy to stay up in the morning, he felt the pain of the fingers reduced, they take away the nitrate
