Surface water is generally coloured and turbid. When total phosphorus is analyzed by luminometer, the monitoring result will be somewhat high.

地面水一般带色且浊，采用光度法分析水样中总磷时，会使测定结果偏高。

Light is emitted when luciferase is exposed to the appropriate luciferin substrate. Photon emission can be detected by light sensitive apparatus such as a luminometer or modified optical microscopes.

在荧光素酶中加入正确的荧光素底物就可以放出荧光，而发出的光子可以被光敏感元件，如荧光探测器或改进后的光学显微镜探测到。
