     CRITERION FOR PREDICTING COLD SHUT MARK
     冷隔缺陷预测判据
短句来源
     The criterion which could predict the occurrence of cold shut mark on sUS304 stainless steel during twin roll casting process was determined by combining numerical simulation with test observation. The criterion was tested and verified by experimental results, and was showed correct and reliable.
