The multivariate linear regression analysis on specific absorption coefficients for pheophytin and chlorophyll a indicates that the specific absorption coefficients for pheophytin was much larger than chlorophyll a at 412 nm; slightly larger than pheophytin at 440nm; and about 3 times larger than pheophytin at 670 nm and 675 nm.
结果表明，412nm波段脱镁叶绿素的比吸收系数远大于叶绿素a；440nm波段，叶绿素a的比吸收系数略大于脱镁叶绿素；670、675nm波段，叶绿素a的比吸收系数约为脱镁叶绿素的3倍。

While the proportion of pheophytin in total pigment concentration increased, the absorption peak in the blue region of spectrum deviated from 440 nm to near 412 nm. The absorption peak height in the blue region was mainly influenced by pheophytin concentration, whereas the height in the red was decided more by chlorophyll a concentration.
随脱镁叶绿素占色素总浓度比例的增大，浮游植物吸收曲线上蓝光吸收峰偏离440nm波段，逐渐向412nm波段靠近，并得到蓝光波段吸收峰的高度由脱镁叶绿素浓度决定，而红光波段吸收峰的高度由叶绿素a浓度决定。
