| 摘 要： | 介绍了在不同温度下，PN结正向伏安特性曲线的自动测量方法。讨论了PN结伏安特性与温度的关系．由于正向结电压小于内建电势差，温度升高或正向结电压增加，正向结电流将增大，温度升高反向结电流也相应增加．当温度趋向OK时。正向结电压趋向内建电势差。

| Abstract: | The auto-measuring means of positive volt-ampere characteristics of PN junction at different temperature is introduced, and the relation of volt-ampere characteristics of PN junction with temperature is discussed. Due to positive junction volt smaller than build-up potential inside PN junction, the positive junction current increases with the raise of temperature or positive junction volt, and the reverse junction current also increases with temperature. The positive junction volt tends towards the build-up potential while temperature goes to 0K. |
