静电场对液态电介质极化作用的实验验证

THE POLARIZATION WHICH THE ELECTROSTATIC FIELD ACTED ON LIQUID DIELECTRIC WAS VALIDATED BY EXPERIMENTS

介绍了静电场对液态电介质极化作用的实验及注意事项．此实验对学生加深理解静电场中电介质的性质具有重要作用．

In this paper, the author introduced not only the design of the experiment, which proved the polarization which acted on liquid dielectric,but also the attention in the course of experiments. Theseexperiments are important in making the students under- stand deeply the character of dielectric in the staticelectricfield.
