To investigate the mechanism of repeating-70 ℃ freeze thawing on human choroidal melanoma cell line OCM-1 .
[目的]研究-70℃反复冻融体外杀伤人眼脉络膜黑色素瘤细胞系OCM -1 的机制.
Based on the mapping from the span to the output of MPS time horizon, the ARMA-BP model can respectively approach and forecast the span and the output time series by virtue of output conversion method with average time span ( OCM-ATS).
基于主生产计划时段长度与产量之间的映射关系,利用平均时段长度折合产量法(OCM-ATS),该模型可用于分别逼近和预测主生产计划时段的长度时序和产量时序。
