对一些已知条件隐蔽、模型新奇、题文隐晦的物理题,用常规的方法往往颇费思量,难以奏效,而在不改变原题所含物理本质特征的条件下,如果对原题进行诸如调动、重组、限定、推广、替换或分解等创造性思维活动,往往可以将它改装成一个物理情景清晰、处理方法常规化的问题,达到事半功倍的效果,我们称这种方法为构造的方法. For some physics problems with hidden conditions, novel models, and hidden topics, the conventional methods are often intensive and difficult to work out. If the physical nature of the original questions is not changed, the original questions are Creative thinking activities such as mobilizing, reorganizing, restricting, popularizing, replacing or decomposing can often be converted into a problem with clear physical scenes and normalized processing methods. This can achieve a multiplier effect. We call this method a method of construction.
