Research on negative deviation rolling of tinplate

镀锡板实现负偏差轧制的研究

When the critical temperature, vapour pressure parameter and the critical pressure and acentric factor are calculated by Roess, Soave and Lee-Kessler equations respectively, the predicted temperatures are all in negative deviation.

采用Roess式计算临界温度，Soave式计算蒸汽压参数，Lee-Kessler式计算临界压力及偏心因子，其预测温度普遍偏低。
