Using gray connection to research relationship between chlorophyll-a and environmental factors in Wulihu Lake in Taihu region was done in the present study.

运用灰色系统理论对淡水湖泊太湖五里湖中叶绿素-a与环境因子的关系进行研究,采用灰关联分析方法探讨太湖五里湖的部分理化因子对叶绿素-a浓度影响的大小排列顺序。

The chlorophyll-a (1) was converted into the chlorins 2b～4b by air-oxidation in acid or basic condition.

在酸碱性条件下对叶绿素-a (1)进行空气氧化反应, 分别得到卟吩衍生物 2b～4b; 通过酯交换和去金属镁离子,将叶绿素-a 转化为脱镁叶绿酸-a 甲酯(MPa) (5), 其 3-位碳碳双键与氯化氢的加成生成卟吩醇(6), 经碱性空气氧化和 E-环重排则转化成紫红素-18衍生物7。

The results showed that light shading could greatly reduce the alga biomass without removing nutrients after 9 days, considering that Chla declined from 130.

结果显示,9d试验后,叶绿素a浓度、COD、浊度、DO分别由遮光前的130。

Ocean primary productivity is based on chla, which mainly denotes itself as the integral of the velocity of photosynthesis of chlorophyll and the density of chlorophyll in euphotic layer.

海洋初级生产力是基于海洋叶绿素a进行计算的,主要为叶绿素光合作用速率与遥感得到的叶绿素浓度在真光层的积分。

It seems nothing happens for the chlorophyll A (Chla) in the leaves of plants, even exposure in strong sunlight of summer.

有机溶剂中的叶绿素a很快会发生光解 ,但即使在夏日炎炎烈日暴晒下 ,叶片中的叶绿素a却没有任何变化。
