Results show that the water contact angle becomes smaller and the surface is rougher after modification.

结果表明，改性后的硅表面接触角减小，粗糙度增加。

A theoretical model for calculating the cutting angle with different crystal planes, orientations and tool orthogonal rakes are described in this paper. It is built with the ultra-precision cutting model by the principle of the maximum specific energy of shear deformation and the mechanism of change of the shear modulus with...

本文利用剪切变形比能最大及单晶材料不同晶面晶向剪切弹性模量不同的原理，结合超精密切削模型，从理论上计算出不同晶面、不同晶向及不同刀具前角超精密切削条件下的剪切角，得到其在不同切削条件下的变化规律，并由此解释了切削加工中由KDP晶体各向异性所导致的工件表面粗糙度的各向异性。
