纵向流动

A multiminate layer vapor screen technique and force measurement technique for an unsteady flow in the intermitted wind tunnel is presented in this paper.

本文介绍在暂冲式三声速风洞中实现了非定常流动的多片光蒸汽屏显示技术和测力技术，并用这两项技术研究了亚声速时70°后掠三角翼模型俯仰振动的非定常流动现象，探讨了由于三角翼模型俯仰振动产生的涡结构与纵向气动力特性之间的相关关

He showed short-and-leggy shifts with a waistless, floating volume.

他展示了纵向的简短和横向的流动的对比。

The second, according to mapping function of blank and product sections, and to many interpolating functions along model-cavity vertical surface, paper has built mathematics model, fluid surface function of special-shaped product plastic deformation and velocity field, gotten basis theory for metal forming prediction, for example empty drawing metal pipe thickness homogeneity and special-shaped product fluid regular, die parameter optimization and integration research of die CAD/CAM.

根据拔制坯料和制品截面映射函数和模腔纵向多种插值函数（直线型、凸型、凹型和三次多项式型），建立了相似异型材、圆形坯料——异型材和异型材——异型材三维金属拔制塑性成形的数学模型和异型材塑性成形的流面方程及流动场方程，为预报金属成形规律（如：空拔管壁均化、异型材流动规律），模腔参数优化及其CAD／CAM一体化研究提供了理论基础。
