【摘要】 对自加热气敏电阻工作电压超过一定值时，由本征激发而产生的热奔走现象机理进行了分析．结果表明，该电压值随空气中ＣＯ浓度的上升而下降，并与气敏电阻自身结构特性有关．更多还原

【Abstract】 Thermal shift phenomena happens as a result of intrinsic excitation during working voltage of self--heating gas sensing resistance is over certainly value.The voltage decreases with increasing CO concentration in air and relates with structure characteristic of gas sensing resistance.更多还原
