浅谈物理原理对物理实验的指导作用

实验原理是物理实验的核心，本文通过对具体案例的分析指出：正确理解实验原理是实验科学性的基本保证，深刻理解实验原理是突破实验难点的关键，掌握实验原理是领会实验设计思想的前提，挖掘实验原理的内涵则是教学创新设计的出发点．

Guiding effect of physical principles to physics experiments

The experiment principle is the core of the physics experiment. Through analyzing the cases, it is indicated that correct understanding of the experimental principles forms the base of the scientific quality of experiments; deep understanding of experimental principles is the key to breaking through the experimental difficulties; mastering experimental principles is the prerequisite for catching the designs of experiments; excavating the intension of experimental principals is the starting point of creative teaching designs.
