反败为胜 实例:德国某造纸厂的一位技师,有一次由于一时疏忽大意,在造纸的某道工序中少放进去一种原料,结果生产出大批不能书写的“废纸”。正当他想着会被老板解雇的时候,一位朋友向他建议说:“考虑一下这样的纸还有没有什么别的用途?”于是这位技师和他的朋友一起,对这批纸反复观察琢磨。终于发现:这种纸吸水的性能很强,蘸在这种纸上的墨水很容易被吸掉。他们发现这一点以后,便对这种纸加以剪裁装订,把它作为一种供书写后吸干墨水用的“吸墨水纸” Reversal defeated the victory Example: A technician at a paper mill in Germany had once lost a certain amount of raw materials in a certain process of papermaking because of a momentary negligence. As a result, a large number of waste papers that could not be written were produced. While he was thinking about being fired by his boss, a friend suggested to him: “Is there any other use for this kind of paper?” So the technician and his friends observed the paper repeatedly. Ponder. Finally found: This paper is very strong in water absorption, and the ink on this paper can be easily sucked. After discovering this point, they cut and stapled the paper as an “ink-absorbing paper” for blotting ink after writing.
