摘　　要：用自行设计的“连续抽运-探测光+脉冲抽运光”的实验系统,在不同波长的连续和脉冲光作用下,研究了细菌视紫红质(BR)膜的瞬态光吸收性质,并着重以632.8nm的激光为连续抽运-探测光研究了BR的质子电荷光循环过程中。The characteristics of instantaneous optical absorption in bacteriorhodopsin(BR) pumped by different wavelength cw and pulsed light were studied with the experimental system of “cw optical pump probe+pulse laser pump” designed by ourselves.Especially, a 632 8 nm laser was used as the cw pump probe light to study the correlation between the optic absorption kinetic characteristics of BR’s every state during the optical cycle process of proton charge together with its instantaneous optical absorption and the intensity of cw pump probe or pulsed pump laser.
