The flucrescence decay of Chlorella pyrenoidosa has been investigated under a variety of conditions in the picosecond and nanosecond time regions. Most of the fluorescence is accounted for by an expression of the form I(t) = I0exp-(At+Bt1/2) though an additional exponential term is required to include a weak component of lifetime 32 ps observable only at the higher pulse intensities. This interpretation reconciles earlier and apparently conflicting data. The weak 32 ps component may be associated with Photosystem I, although the possibility that it is an artefact of the high intensity pulses used cannot be excluded at present. The main fluorescence, described by the equation above is attributed to the antenna chlorophyll and is of the form which would be expected from a single light harvesting array with trapping at randomly distributed sites.
在皮秒和纳秒时间区域内的各种条件下，对小球藻的荧光衰减进行了研究。尽管需要一个额外的指数项来包含仅在较高脉冲强度下才可观测到的32皮秒寿命的弱组分，但大部分荧光可由I(t) = I0exp-(At+Bt1/2)形式的表达式来解释。这种解释调和了早期明显相互矛盾的数据。尽管目前不能排除其是所用高强度脉冲的人为产物的可能性，但32皮秒的弱组分可能与光系统I有关。上述方程所描述的主要荧光归因于天线叶绿素，其形式是具有随机分布捕获位点的单个光捕获阵列所预期的。
