A standard metal ball with known RCS value has been used as the calibration body in the external calibration experiment which used a relativecalibration method and acquired the calibration data.
实验时采用已知rcs值的标准金属球作为定标体,使用相对定标法对系统进行外定标实验,得到定标数据。

Such impurities requiring calibration calculation normally use main component as reference and use relative retention time for orientation, such value are to be recorded under each type.
这些需作校正计算的杂质,通常以主成分为参照采用相对保留时间定位,其数值一并载人各品种项下。

We measure that in a more relative sense; this will give us a calibration.
