物理中的近似估算法

物理估算,一般是指依据一定的物理概念和规律,运用物理方法和近似计算方法,对所求物理量的数量级或物理量的取值范围,进行大致的推算.灵活的运用物理知识对具体问题进行估算,是科学素质的重要体现,因此,近些年来,不论是教材编写、还是高考命题,都加强了对估算题的重视程度.

Physics Teaching Method to Estimate the Approximate

Physical estimates generally refers to a certain extent based on the concepts and laws of physics and uses physical and approximate calculation method to estimate the approximate on the order of the physical or the physical range from roughly the projected.Flexible use of physical knowledge of the specific issues of estimates is an important manifestation of the quality of science.So,either writing textbooks,or college entrance examination proposition draws great attention to the importantion of the estimat...
