Detecting the density of pollutant gas is one of the important applications of lidar. The minimumdetectableconcentration is a key index of lidar.
探测大气中污染气体的浓度是激光雷达的一个重要应用方面，最小可探测浓度是衡量一个雷达系统的重要指标。

As the 10 groups, 2 groups were lower than the minimumdetectableconcentration, and we can not analysis the relationship between the caries status an MG1 content in the plaque.
由于10组有2组低于最低检测浓度，故无法对儿童菌斑MG 1含量与患龋状况之间的关系进行分析。
