Specific radiographic parameters such as LIV and fusion levels,disc wedging,LIV obliquity,global coronal ba.
5年(1~3年),统计分析LIV与融合椎体节段数、椎间盘楔形变、LIV倾斜度、躯干平衡指标等影像学资料之间的关系,分析椎间盘楔形变与躯干平衡之间的关系。
A formula of contact area between the shaft part of workpieceand flat parts of forming wedges in rolls was therefore derived, as well as anempirical formula using effecting coefficient of surface rolling deformationgiven by regression analysis.
通过实验验证了三辊楔横轧中轧件轴平行部对轧辊变形楔平直部分碾压力的存在,它是楔横轧时轧制力的重要组成部分。
