摘要： 应用光脉冲技术借助计算机由FFT运算测定了n-InP在Fe~(3+)/Fe~(2+)溶液中复收集率图, 结果为一第四象限内半园, 由理论模型从园心位置、园半径及特征频率可算出三个动力学参数; 研究了电极电位及光强对这些参数的影响, 并对结果进行了讨论。

Abstract: In this paper the complex collection efficiency figures of n-InP in Fe~(8+)/Fe~(2+) solution are determined with light pulse technique by fast Fourier transformation using microcomputer. It is a half circle at fourth quadrant. According to theoratical model three photoelectrochemical kinetic parameters are calculated from the position of circle centre, the radius of circle and the characteristic frequency. Influences of the electrode potential and the light intensity on those parameters are dermined and the results are discussed.
