| 摘 要： | 电容器是广为应用的电子器件之一.由于电容器的边缘不规则和具有明显的边缘效应,使电容的标称值与其实际值不符,常会引起无法预料的电容击穿等线路故障.通过对两类具有非理想边缘的矩形平行板电容器电容的分析,得出了具有较明显边缘效应的电容器电容的半定量结果和两板不严格平行的电容器电容的定量结果,指出了在实际应用中应注意的有关问题.

| Abstract: | A capacitor is one of the most widely used electronic elements.Difference between the nominal value and the actual value of a capacitor occurs due to edge effect,which may cause unexpected breakdowns of the capacitors.Two kinds of rectangular parallel-plate capacitors with non-ideal edges are analyzed in the paper.The semi-quantitative capacitances in capacitors with non-ideal edges are determined.The paper calculates the quantitatihe capacitances in plate capacitors uhich are not strictly paralleled.Some noticeable relevant issues in practical applications are proposed. |

| Keywords: | capacitor with nonideal edges rectangular parallel-plate capacitor edge effect semi-quantitative capacitance quantitative capacitance |
