Rather the detection limit is shown to be sufficiently low by the analysis of samples with known concentrations of analyte above and below the required detectionlevel.
而是，通过分析含有高于和低于必需的检测水平的、已知待分析物浓度的样榀，以显示检测限度足够低。

The testing content and procedure on detection range with a certain new model low light level observation device are described.
叙述国产某新型微光观察仪探测距离的测试内容和方法，并得出具有一定参考价值的结论。

This method also has characteristic of low amplitude detection threshold, it can detect weak signals with amplitude value smaller than 10-3 level.
