The effects of mud concentration, gas to liquid ratio and the hydraulic resident time on the removal rates of COD and NH3-N were investigated.
实验考察了污泥浓度、气液比及水力停留时间对生物降解废水中COD和氨氮(NH3 - N)的影响。
The RG Dipeptides were condensated from N-protected Arg and C-protected Gly by mixed anhydrides method. Then Asp and RG Dipeptides were synthesized RGD Tripeptides in liquid phase.
由N-保护的精氨酸、C-保护的甘氨酸采用混合酸酐法缩合成RG二肽，再与天冬氨酸在液相中合成RGD三肽。
