查询词典 chlorophyll

The excited and emission spectra of anthrone derivative, lactoflavin and chlorophyll a in different solvents are taken and the fluorescence yields has been estimated. The results show that the emission spectrum depends on the structure of molecule, and shifts to red with increasing of number of π electrons in the molecule.It is...

It was shown that microcystis colonies floated upward to the water surface in light shading by means of monitoring Chlorophyll a contents at different water depths,.

光限制初期铜绿微囊藻群体存在逐渐上浮聚集的趋势，这与其自身的浮力调控机制有关。

Researchers have tried to mimic the process used by plants with experimental systems that use some of the components of photosynthesis, such as chlorophyll, which makes plants green and helps trap light , and catalysts which facilitate the process of converting carbon dioxide, water and sunlight.

研究人员一直试图用实验体系模拟植物的光合作用。他们想利用一些光合作用中的原料，例如让植物呈现绿色并有助于俘获光子的叶绿素、促进二氧化碳转化过程的催化剂、水和阳光。

Fourthly, taking three groups of water quality data of Jinhe River as original data, prediction to water quality of the river was made. Compared with real monitored value, the error of predicted value of all of simulating terms, including dissolved oxygen, bio-chemical oxygen demand, chlorophyll a, organic nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, organic phosphorus, dissolved phosphorus and temperature, were basically within error limit of 20%, which validated the validity of the model.

第四，以津河三组水质数据为原始数据，通过建立的模型对津河水质进行预测，水质变量溶解氧、BOD、叶绿素、有机氮、氨氮、亚硝酸盐氮、硝酸盐氮、有机磷、溶解性磷和温度的预测值与实际监测值均在所设定的误差范围20%之内，验证了模型的有效性。
