the IS normalized MF was calculated by dividing the MF of the analyte by the MF of the IS. The stability tests were conducted on the bench-top for 6 h, 3 freeze/thaw cycles, post-preparative for 8 days in the autosampler (set at 10 ?C) and in a freezer set at ?30 ?C for 1 month. Analyte concentrations were calculated using a 1/x2 weighted linear least-square regres-sion analysis of the standard curve. 这几句啥意思啊 |

IS（Internal Standard) 内标 MF (matrix factor）基质效应因子 IS normalized MF：内标归一化基质效应因子 the IS normalized MF was calculated by dividing the MF of the analyte by the MF of the IS. 待测物与内标的MF的比值为内标归一化基质效应因子 The stability tests were conducted on the bench-top for 6 h, 3 freeze/thaw cycles, post-preparative for 8 days in the autosampler (set at 10 ?C) and in a freezer set at ?30 ?C for 1 month. 稳定性试验： 室温稳定性：试验台上放置6h 冻融稳定性：3个冻融循环 处理后样品稳定性：自动进样器内放置8天（某温度）、冰箱内放置1个月（某温度）。 Analyte concentrations were calculated using a 1/x2 weighted linear least-square regres-sion analysis of the standard curve. 待测物浓度由标准曲线计算，线性拟合：最小二乘法，加权因子1/x^2 。 |
