液体压强教学演示仪的设计与制作
摘要
本文结合理论与实践对初中浮力教学中液体压强教学仪器的设计和制作给予论述,设计并制作了液体对容器壁压强演示仪、自制U行液压计、液体压强与流速关系演示仪,并在论述过程中,结合我国初中物理演示实验仪器的现状,以及当前物理教学中存在的问题提出改革的思想。针对三组仪器的制作及实验过程进行了详细的论述。详细的论述了普通物理实验仪器的设计思想和基本要求。提出了在教学过程中合理使用自制演示仪完成教学的设计假说,以达到使学生更好的理解液体压强教学内容的目的,并对教学过程中使用演示仪时需注意的问题给予论述。

DEMONSTRATOR LIQUID PRESSURE OF TEACHING DESIGN AND PRODUCTION
ABSTRACT
bination of theory and practice of teaching junior high fluid pressure buoyancy equipment design and production of teaching given to discussion of design and production of liquid pressure on the container wall demonstration instrument, mading U-line manometer, liquid pressure and velocity relationship Demonstrator demonstrator and discusses the process, Combineding with junior high school physics demonstration of the status of laboratory instruments and the current problems in physics teaching ideas to reform. Three sets of equipment for production and test process are discussed in detail. Detailed discussion of the general physics laboratory instruments and basic requirements for design ideas. Proposed fair use in the teaching process of teaching self-presentation device plete the design hypothesis, in order to achieve a better understanding of the students the content of the liquid pressure of the purpose of teaching, and demonstration instrument used in the teaching process should pay attention to
