The interpolation cutter axis vectors,which turn gradually and evenly,were obtained using smoothing interpolation algorithm of spatial vector.
为了解决数控刻楦中刀轴矢量方向相对鞋楦表面法向频繁变换而造成冲击或发生干涉等问题,提出一种刀轴矢量平滑化插值方法。
Here,an axial vector R is selected as the order parameter to reflect the change of symmetry in antiferroelectric phase NH_4H_2PO_4.
选用轴矢量R作为序参量来描述NH4H2PO4(ADP)晶体反铁电相变中对称性的变化,应用居里原理,恰能得到NH4H2PO4(ADP)晶体反铁电相的正确对称性所属点群P2(C2)。
In this paper, an axial vector R is selected as the order parameter.
本文提出选用轴矢量R作为序参量来描述反铁电相变中对称性的变化。
