在工厂里,我们常采用组织“攻关”的方法,发挥群众智慧,以解决生产中的枝术难题。但有些“攻关”,由于违背了科学的原理,因而尽管耗费不少精力,仍不能取得进展。现提供这个例子,目的是引起设计人员的注意。工艺人员遇到这类问题,也应如实地把道理讲清楚,不要碍于情面,明知不可能而抱着试试看的态度,徒然浪费人力物力。 In the factory, we often adopt the method of organizing “tackling problems” and give play to the wisdom of the masses to solve the problems in production. However, some “tackling problems” can not make progress despite consuming a lot of energy because they violate the principle of science. This example is provided for the designer’s attention. Craft workers encounter such problems, they should truthfully make it clear, do not obstruct the situation, knowing it is impossible to hold the attitude of trying, in vain to waste human and material resources.
