valgus

Objective To investigate the effect and advantage of oblique os teotomy of the first metatarsal in treatment of hallux valgus deformity.

目的　探讨和总结第一跖骨斜行截骨术治疗　外翻畸形的临床效果和优越性。

Using a new model for analyzing forming parameters in external inversion process of round tubes on fillet die;

利用一种新的模型解析圆角模外翻管成形参数

Tube inversion is a special metal forming process in which a tube, when subjected to axial compression, will undergo external inversion or internal inversion to form double-walled tubular components that are difficult to produce by any other manufacturing process.

(1)采用轴对称旋转壳体的薄壳理论对内翻及外翻变形过程进行了力学分析。
