我们在解题时,根据某种需要,要么将题设条件中的关系设想在某个模型上,要么结合题设条件产生联想构造某种关系式,要么将已知条件与相关知识进行有机组合、等价转化而构造出一种新形式,从而使问题得以解决。我们把这种在思维过程中,对已有的知识和方法采取分解、组合、类比、推广、变换和等价转化等手段,进行思维的再创造,并构造新的关系式、图形或命题来帮助解题的思想,称之为构造思想。 When we solve problems, according to a certain need, we either envisage the relationship of the preconditions in a certain model, or combine them to produce the associative relations or combine the known conditions with relevant knowledge , The equivalent transformation and the construction of a new form, so that the problem can be solved. In this process of thinking, we take the means of reconstructing, combining, analogizing, popularizing, transforming and transforming existing knowledge and methods to reconstruct the thinking and construct new relations, figures or propositions Help solve the problem of thinking, called the tectonic thinking.
