| 摘 要： | 本工作是采用对空心圆柱形玻璃管体容比的测量，实现其玻璃介电常数（ε＿ｒ）的测定。所得结果说明同轴圆柱形电容器的电容公式只有当其高度Ｈ与壁厚ΔＲ之比大于７０时才基本适合，否则理论值与实际值将产生较大的偏离。

| Abstract: | The glass dielectric constant is mersured in propotion of inner volume tocapacity.Measuring results show that the capacity formula of co-axis cylinder condenser isin agreement with the experimental result,of only the ratio of H(the height of glass cylin-der)to ΔR(the thickness of hollow glass cylinder)is larger then 70. |
