摘要
任何科学,都是在一定条件下成立的,是对事物的"近似"描写。本文通过对两个问题的解决,具体阐述了"近似"方法的运用。"近似"是科学的普遍方法,至少是自然科学的普遍方法。
Any science, established under certain conditions, is an approximate description about things. Through solving two problems, this paper specifically discusses the use of "approximation". Approximation is a universal method of sciences, at least a universal method of natural science.
