从近两年贵州各地区的物理中考来看,压强的考点还是主要集中在综合密度、重力公式,解决固、液压强的简单计算上。对固、液、气压强的特点应用和影响固、液压强大小因素的实验探究等出现的考查几率不高,即使要在中考试题上出现也只是涉及基础的考查,难度不大。所以压强知识最终还是要求对固、液压强公式的掌握和应用,由于最终公式的熟悉应用还是要有前面基础知识的理解,所以要学好压强,必须
From the last two years of physical examination in various regions of Guizhou point of view, the pressure test sites or mainly concentrated in the integrated density, gravity formula to solve the simple, strong hydraulic calculations. The solid, liquid and gas pressure characteristics of the application and the influence of solid and hydraulic factors such as the small test to explore the probability of occurrence is not high, even in the examination questions appear only on the basis of the test, not difficult. Therefore, knowledge of pressure finally requires the mastery and application of solid and hydraulic formulas. Since the familiar formulas of the final formulas still need to have the understanding of the previous basic knowledge,
