本文提出了反射阵的概念，揭示了非正交函数谱分析的镜像对称性。
Thus, the concept of reflection matrix is proposed and the mirror symmetry of spectral analysis for non orthogonal function is revealed.
方法：视头颅为一整体，根据镜像对称性原理，制成由面弓、滑动定位尺、轨限、耳杆和额托等附件构成的颧骨复合体骨折定量复位校正仪。
Methods: According to the mirror imaging symmetry principle, we assumed the skull as an entirety and design the localizer to measure the projections of zygoma and zygomatic arch.
