While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

A detailed investigation was conducted in this paper on the flow asymmetry and its influencing factors over an ogive slender body model, incorporated with surface pressure measurement, skin oil flow pattern visualization, hot wire dynamic signal acquasition and other relevant approaches, in a low turbulence wind tunnel.The obtained test results demonstrate good accordance with those published abroad in the behavior, tendency of the flow asymmetry and the effects due to Reynolds number, incoming turbulence and model geometry etc.

The paper analyses the dements that inflences the processing precision of thin major axis on the base of its structure charac- teristics.

从细长轴的结构特点出发，分析了影响细长轴加工精度的因素，并针对产生误差的根源，从改变加工方式、工装结构和刀具参数等方面着手，提出了相应的解决措施。

Therefore, for improving the accuracy of exceed slender axle on turning,must need to do with the lathe fixture and cutting tool for further improvement. In order to reached the requirements of precision machining,in machining process must use follower rest、flexible active thimble、space block and bracket etc fixture and assistive device.

超细长轴在车削加工中承受自身重力、切削力、高速旋转产生的离心力的作用，极容易出现振动与弯曲变形现象，增大轴的几何形状误差，而超细长轴的轴向尺寸较大，直径较小，热扩散性及刚性差，受切削热作用会在轴向发生线性膨胀，若在轴向的伸长量无法得到消除，轴将受迫弯曲，从而影响轴的精度。

According to the resonance of mechanical machining,the relationship between the spindle speed of lathe and the surface quality of the workpieces was studied on turning a long and thin axis on the lathe.
