固体、液体的压力和压强问题在中考中占 有一席之地,但有的同学,碰到这类题,往往不 知道是先求压力还是先求压强,应用什么公式 解决．有时常因运用公式不当而造成错误．对 此本文作一初步探讨,以便使初学者有较全面 的了解． 一、固体类 分析自然科学中运用压强公式解决有关问 题的计算中,大都是求算固体对水平面产生的 固体、液体的压力和压强问题在中考中占 有一席之地,但有的同学,碰到这类题,往往不 知道是先求压力还是先求压强,应用什么公式 解决．有时常因运用公式不当而造成错误．对 此本文作一初步探讨,以便使初学者有较全面 的了解． 一、固体类 分析自然科学中运用压强公式解决有关问 题的计算中,大都是求算固体对水平面产生的
Solid and liquid pressure and pressure problems have a place in the middle school entrance examination. However, some students encounter such questions and often do not know whether to seek pressure or to seek pressure first, and what formula to apply. Sometimes errors are caused by improper use of formulas. A preliminary discussion of this article is made so that beginners can have a more comprehensive understanding. First, the analysis of solids in the natural sciences using pressure formulas to solve relevant problems in the calculation, mostly to calculate solids on the water level of solids, liquid pressure and pressure problems in the examination has a place, but some students, encountered this type of Questions, often do not know whether to seek pressure or pressure, apply what formula to solve. Sometimes errors are caused by improper use of formulas. A preliminary discussion of this article is made so that beginners can have a more comprehensive understanding. I. Solids Analysis of the use of pressure formulas in the natural sciences to solve problems related to the calculations, most of them are to calculate the solids produced on the horizontal plane.
