所谓等效,是指在解决某问题时,可以运用甲、乙、丙、丁等多个方案,而它们的效果是等同的. 人们可以应用物体之间的等效关系,把一个较为复杂的问题简化或将一个生疏的问题转化为熟知的问题的思维方法叫做等效思维. 这种思维方法广泛地运用于物理学的研究和应用中.如力的合成与分解、波的迭加、电路的等效变换、电容的串并联计算,都属于等效思维在物理学中的应用。
The so-called equivalent means that when solving a problem, you can use multiple schemes such as A, B, C, and D, and their effects are equivalent. People can apply the equivalent relationship between objects and put a more complicated one. The method of thinking that simplifies the problem or converts an unfamiliar problem into a well-known one is called equivalent thinking. This method of thinking is widely used in the study and application of physics. The synthesis and decomposition of force, the superposition of waves, and circuits The equivalent transformation and series and parallel calculation of capacitance are all applications of equivalent thinking in physics.
