The effects of different phosphorus concentrations of water system on DTP, P-in-cell content of tissues (QP) and cell multiplication of Microcystis aeruginosa were studied in laboratory experiments.

通过室内模拟的方法研究了在磷质量浓度不同的水体条件下，在铜绿微囊藻水华形成过程中微囊藻的增殖特征及细胞内磷、可溶性磷的变化特征。

Ammonium sulfate is also used as a fertilizer (although in much higher concentrations), but it only contains nitrogen but neither phosphorus nor potassium.

作为肥料应用的硫酸铵浓度会更高，但其中只有氮的成分，没有磷或钾。

In certain range of concentrations, there existed a good linear correlation between the average blueness of image and the concentration of phosphorus in solution after chromogenesis.

在一定的浓度范围内，显色后的溶液磷浓度与图像的平均蓝色度有较好的线性关系。
