In view of the lack of consideration for the random and the fuzzy of design parameters in traditional optimal design for the machine tool spindle,the fuzzy reliability is introduced into the process, and then a mathematical model is estadlished in the light of the optimal design theory.

针对机床主轴常规优化设计不考虑设计参数的随机性和模糊性，提出将模糊可靠性引入到主轴的优化设计中，在常规优化设计的基础上建立了机床主轴模糊可靠性优化设计的数学模型。

To further study this problem, the optical axis is rotated by an arbitrary angle. A striking phenomenon is discovered that the Brewster angle is always equal to the rotation angle. This is because the waves in the direction perpendicular to the optical axis become evanescent since the permittivity is positive while the permeability is negative in this direction.

然后进一步的研究了主轴不垂直于界面的情况，发现主轴转动的角度恰好等于此时的Brewster角，这是因为此时垂直于主轴的方向上介电常数为正磁导率为负，只有倏逝波而没有可传播的波存在，因此反射系数为0。

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.
