Numerical simulations on the quasi-steady and unsteady flow in Aachen 1-1/2 Axial-Flow turbine stages are performed in this paper, and the influences of the rotor-stator interaction on the fluctuating velocity, flow angle, wall-pressure and loss mechanism are discussed.

本文对Aachen一级半轴流式透平进行了准定常及非定常流动的数值模拟，讨论了引发动静干涉效应的主要因素，分析了非定常效应对叶栅通道中脉动速度、气流角、型面压力分布以及损失结构的影响。

According to the design principles and analysis and comparison of economy, application, comfortability, safety and reliability , the heavy truck drive axle structure, layout ways, and the final drive assembly, differential assembly, the bridge case and axle structure can be determined; and the strength checking of brake parts, as well as major components improves overall design of the driving axle.

本文认真地分析参考了江淮HF15015卡车驱动桥以及韩国现代468号驱动桥，在论述汽车驱动桥运行机理的基础上，提练出了在驱动桥设计中应掌握的满足汽车行驶的平顺性和通过性、降噪技术的应用及零件的标准化、部件的通用化、产品的系列化等三大关键技术；阐述了汽车驱动桥的基本原理并进行了系统分析；根据经济、适用、舒适、安全可靠的设计原则和分析比较，确定了重型卡车驱动桥结构形式、布置方法、主减速器总成、差速器总成、桥壳及半轴的结构型式；并对制动器以及主要零部件进行了强度校核，完善了驱动桥的整体设计。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
