类比推理是合情推理的重要形式,它是根据两个(或两类)对象之间的某些方面的相似或相同,推演出它们在其他方面也相似或相同的推理方式.类比推理在数学发现中具有十分重要的作用,正如德国天文学家、数学家开普勒指出:我珍视类比胜于任何别的东西,它是我最可信赖的老师,她能揭示自然界的奥秘. Analogical reasoning is an important form of adulteration reasoning, which deduces the reasoning ways that they are similar or the same in other respects according to the similarity or the sameness of some aspects between two (or two kinds) Discovery has a very important role, as Kepler, a German astronomer and mathematician, points out: I cherish analogies over anything else, and it is my most trusted teacher who reveals the secrets of nature.
