压强是中考的热点内容,主要考查压强的相关计算及其应用,大气压强的作用及其现象解释,流体压强的特点。本章在中考中各种题型都有可能出现,是力学中计算量较多的内容。课程标准对本部分提出的具体要求是:通过实验,理解压强,知道日常生活中增大和减小压强的方法;通过实验,探究并了解液体压强与哪些因素有关;知道大气压强与人类生活的关系;了解流体的压强与流速的关系及其在生活中的应用。重点1:压力
Pressure is the hot spot in the exam, the main test of pressure related calculations and applications, the role of atmospheric pressure and its interpretation of the phenomenon of fluid pressure characteristics. This chapter in the exam in a variety of questions are likely to occur, is more computational content in mechanics. Curriculum standards for this part of the specific requirements are: through experiments to understand the pressure, to know the daily life to increase and decrease the pressure of the method; through experiments to explore and understand the liquid pressure and what factors; know the relationship between atmospheric pressure and human life; Understand the relationship between fluid pressure and flow rate and its application in life. Key 1: Stress
