| 摘 要： | 针对压电陶瓷的压电系数实验测量中仪器调节的困难,通过放置一个三面箱体辅助仪器来改善对光路的调节,同时在给压电陶瓷施加电压的电路中接入电压报警器,有效控制施加在压电陶瓷上的电压大小,以此避免压电陶瓷的疲劳受损乃至被烧坏。

Improvement of the Measurement of Piezoelectric Coefficient in Piezoelectric Ceramic Experiment |

| Abstract: | To solve the difficult of adjustment in the piezoelectric coefficient measurement of piezoelectric ce-ramics,we placed a box with three surfaces as the auxiliary instrument.This box has a very good guidance func-tion to adjust the light path.A voltage alarm was applied in the piezoelectric ceramic voltage circuit to control the voltage on the piezoelectric ceramic,which can avoid the damage of piezoelectric ceramics effectively. |
