高考把对能力的考核放在首要位置。其中有一个能力要求为“应用数学处理物理问题的能力”(指:能够根据具体问题列出物理量之间的关系式,进行推导和求解,并根据结果得出物理结论,必要时能运用几何图形,函数图象进行表达、分析)。图象的考查成为近年来高考命题的重点之一,要做到应用数学处理物理问题的能力,就要能够从图象中获取有用的信息,要知道图象斜率、截距、面积、交点所代表的物理意义,要做到会识图、会用图、会作图。
The college entrance examination puts the assessment of competence on the forefront. One of the capability requirements is “ability of applied mathematics to deal with physical problems” (refers to: the relationship between physical quantities can be listed according to specific problems, derivation and solution, and based on the results to draw physical conclusions, if necessary, can be used Geometry, function images for expression, analysis). Examination of images has become one of the focuses of the college entrance examination propositions in recent years. To use mathematics to deal with physics problems, we must be able to obtain useful information from images. We must know the slope, intercept, area, and intersection of images. The physical meaning of the representative should be understood by drawing pictures, using pictures, and drawing pictures.
