天线色素

推测小偃54PSⅠ可能通过将能量较多地分配给长波长状态的叶绿素分子和保持相对较少的天线色素分子，以避免过多的能量向P700反应中心传递，而起到保护作用。

Presumably in PS ⅰ of " Xiaoyan 54 ", excessive energy was distributed to long wave chlorophyll molecules and the number of antenna pigment molecules was less , so that less energy was transferred to the reaction center P700 and thus it was protected .

表面活性剂使PSⅠ颗粒长波长荧光急剧下降，并在680nm左右出现新的荧光发射峰，可见其阻碍了激发能由天线色素向反应中心的传递。

The presence of surfactant could make the long wavelength fluorescence emission decrease greatly and a new fluorescence peak appeared around 680 nm , it was obvious that the surfactant interceded the transfer of excitation energy from antenna pigments to reaction center .
