Whether this is due to shapefactor of scatterers corresponding to the applied high frequency remain unclear to date.
到底此现象是因为高频率超音波可较好的解析散射子的形状或其他因素，至今仍不太清楚。

Based on the reduced scale ring rolling and finite element simulation materials axial transferring pattern was studied and a formability evaluation method was proposed including the shapefactor.
摘要研究了大型复杂环件形状因素和轧制速率对成形性能的影响规律。
