摘　　要：研究了高速离心机在各种转速下分离人乳腺癌细胞MDA-MB-453的效率,为揭示总体趋势,将实验数据应用灰色序列算子生成紧邻均值序列,进而发现,随着离心速率的不断上升,细胞分离产量与离心速率大致呈正相关关系.在800 r/min时,分离曲线出现拐点,说明分离乳腺癌细胞的转速下限应取800 r/min.This work focuses on the separating efficiency of MDA-MB-453 cell line under different centrifugal speed. Then based on the grey system theory, the separating efficiency is nearly positively related to the centrifugal speed within the range of our research. There is an inflexion when the centrifugal speed is 800 r/min; it shows that the lower limit of centrifugal speed to separate the MDA-MB-453 cell line is 800 r/min.
