【摘要】 分析了光电效应实验中阳极光电流和阴极光电流的形成机理.探索了二者之间的关系.阳极光电流值的K倍与阴极光电流值关于原点对称,因此当K足够大时,用电压大于0时的实测电流值代替阴极光电流值,可以求得电压小于0时的阳极光电流值.更多还原

【Abstract】 The mechanism of anodic and cathodic photocurrent in photoelectric effect experiment was analyzed,and the relationship between them was researched.Because of the mirror symmetry between K times the anodic photocurrent intensity and the cathodic photocurrent intensity,the cathodic photocurrent could be replaced by the measured current intensity when K was large enough and the voltage was greater than zero.Thus the anodic photocurrent value could be calculated when the voltage value was less than zero.更多还原
