| 摘 要： | 利用分析天平，测出了带电平行板电容器两金属板间的相互吸引力F，根据F与两极板间电压U的函数关系，对测量数据进行回归计算，得出平行板电容中电介隔片的相对介电常量。 |
| 关 键 词： | 测定 相对介电常量 电介质 平行板电容器 天平 |

| Abstract: | In the experiment, an analytical balance is used to measure the mutual attraction F between the two plates of a electrified parallel plate condenser. According to the functional relationship between F and U , which refers to the voltage of the condenser, we regress and count those figures and work out the relative permittivity of the dielectric spacer in the condenser. |
| Keywords: | relative dielectric constant dielectrics parallel plate condenser analytical balance |
