The multiple stage treatment -ion bombardment plus high frequency quenching is that the parts first should subject to ion bombarded treatment and then to high frequency quenching and low temperature tempering. The steel is made to have double effects both the ion bombardment and high frequency quenching hardening at the same time," that consequently, has increased its surface hardness, abrasion resistant and fatigue property in a large degree. From experiments it has been shown that the evident results have been obtained through the multiple stage treatment after either ionic nitri-ding or soft ionic nitriding treatment and then high frequency quenching.1. Microstructure that subjected to multiple stage treatment is tinier than ones that subjected to ion bombarded treatment or high frequency quenching singly. After high frequency quenching for a short time, a brilliant white compound layer of ionic nitriding or soft ionic nitriding became incontinuous granular, diffused as compounds of ε- Fe2-3(N, C) plus γ'-Fe4N and Fe3(C, N), and so on. After quenching, martensite contained nitrogen is formed.2. Multiple atage treatment may thicken hardening layer, and increase surface hardness and abrasion resistance.3. After the multiple stage treatment, the surface of the part possesses higher residual pressure stress than one that encountered to ionic nitriding (about 1 - 6 times higher) hence, the fatigue property and use life of the part can be increased, its notch sensitiveness is reduced, and the development of the crack in the part is limitedThe multiple stage treatment- ionic nitriding treatment plus high frequency quenching can satisfy the needs of various parts for properties, such as the abrasion resistance of surface, overstanding heavily load or interchangablc load. This is able to increase remarkably the mechanical properties and use life, and would become one of the advanced treatment processes in the 80's. Hence, it will play an important role in the field of metal treatment

钢的复合表面强化处理,是将零件先进行离子轰击热处理,而后再进行高频淬火和低温回火的一种操作,属于复合热处理之一。经此处理可同时发挥离子轰击热处理强化和高频淬火表面强化的双重作用,从而能大幅度提高表面硬度、耐磨性,并造成高的表面残余压应力,提高钢材疲劳性能,延长零件的使用寿命。试验表明,经复合表面强化处理后,取得明显效果。 1.复合热处理表面强化后的显微组织较单一离子轰击热处理或高频淬火者为细。经短时的高频淬火后离子氮化(或软氮化)的白亮化合物层。成为断续颗粒状或锯齿状,为。-Fe_2~3(C.N)+r'-Fe_4N以及Fe_3(C.N)等化合物。扩散层淬成为含氮马氏体。 2.复合热处理强化可以进一步提高硬化层深度,进一步提高表面硬度和耐磨性。 3.复合强化处理后,零件的表层具有高的残余压应力(比离子氮化者可提高2~6倍),从而能大幅度提高疲劳性能和使用寿命,降低缺口敏感性,阻碍裂纹的扩展。 试验认为,离子轰击热处理+高频淬火表面强化处理,可以满足表面耐磨,承受重载和交变载荷的各种零件的性能要求。能显著提高其机械性能和使用寿命,节约电能,可能成为80年代的优秀表面强化新工艺之一而发挥其巨大作用。

The paper presents the results of measurement of the static pressure and swirl in the flow through an S-shaped duct of typical air intake proportions mounted in a wind tunnel and tested at different incidence.In order to reduce the magnitude of swirl at high incidence,two methods have been studied-one,to change the distribution of pressures by means of a spoiler and two,to re-energize the separated flow with an inflow of free stream air through auxiliary inlets.The results show a small degree of swirl at low incidence which takes the classical pattern of two contra-rotating flows,and a large degree of swirl at high incidence,in the form of a single rotating flow.Of the anti-swirl devices,the spoiler is the more powerful and can be sized either to reverse the swirl direction or to eliminate the swirl completely.A parameter of swirl coefficient,SC60,has been suggested,Values of SC60 at 30°incidence are 0.188 for the duct as designed,0.068 for the arrangement with auxiliary inflow and-0.039 with a spoiler of width 0.15 times throat width.The various arrangements tested,together with results of an earlier study,shed useful light on the general nature of swirl in an S-ductp its method of generation and its final form and magnitude.

本文给出了具有典型飞机进气道比例的S形管道在不同攻角下,压力分布和旋流的实验结果。为了减小大攻角下的旋流,研究了两种方法:一是通过扰流板改变管道内气流的压力分布,二是通过辅助进气门引入自由流空气,向分离流补充能量。结果表明,在低攻角下旋流很弱并呈现为典型的反向旋转对涡二次流动,而在高攻角下则为一个很强的单涡旋转流动。至于反旋流措施,扰流板的效果最好,通过变化其尺寸不仅能改变旋流方向,而且还可完全消除旋流。本文建议用一个旋流系数,SC_(60),来描述名义发动机进口处的旋流。其值对原设计模型在30°攻角时为0.188,而通过辅助进气门引入自由流空气向分离流补充能量后为0.068,当采用一个0.15倍喉道宽度的扰流板时,旋流系数变为-0.039。本研究使S形进气道中旋流的产生、发展和性质得到进一步的认识。

Based on our initial practice of applying B-spline method to computer aided geometric design of automobile bodies,this paper presents the algorithm, properties and applying examples of the nonuniform B-spline curves and surfaces combined with a multi-knot method. Besides, some problems about the application going and fitting the surface with more than four boundaries, piecing one surface of B-spline method to CAGD,such as smoothing the nonuni- form B-spline curve, designing and fitting the surface with more than four boundaries, piecing one surface to another (including additional geometric modelling) and computing the contours of arbitrary sections.An NC (Numerical control) drawing program, designed with the aid of the B-spline multi-knot method, is also introdused.Using the information of multiknots,the program can generate automatically NC instructions or NC paper tapes. without the need of user's writing source program and therefore it shows to a larger degree the advantages of automatical programming.The methods and the programs introdused in this paper have certain generality and may be applied to geometric design of products having complex contours.

本文根据作者应用B样条方法进行计算机辅助汽车车身覆盖件几何设计的初步实践,介绍了重节点非均匀B样条曲线与曲面的算法、性质和应用实例;并对CAGD中应用B样条方法的其它几个问题,诸如非均匀B样条曲线的光顺、具有四条以上边界的曲面造型、曲面拼接与追加造型,任意斜截面的外形计算等,进行了一些探讨。本文所介绍的用重节点非均匀B样条方法设计的数控绘图程序,把前置与后置有机地结合起来,自动生成绘图指令信息与控带,不需用户书写源程序,在更大程度上体现了自动编程的优越性。本文所用的方法和所设计的程序具有一定的通用性,可应用于其它具有复杂外形的产品的几何设计。
