The result indicated that two synthesized com-pounds have obvious absorption at near infrared wave band,optical density was near 3,and visible light transmittance of them are all higher than 57%.

结果表明,所合成的化合物在近红外区均有明显的吸收,光密度接近3,并且在可见光区透过率大于57%,可作为激光防护的近红外激光吸收剂使用。

Methods: The PAE was determined by the spectrophotometric method using AVANTAGE Microbiology System.

方法:应用AVANTAGE自动微生物分析仪的光密度法测定培氟沙星的抗生素后效应。
