2) the symmetrical mirror image
镜像对称
1.
With the methods of Navier-Stokes equation and the symmetrical mirror image, the numerical simulation is carried out about the three-dimensional fluent field produced by the low-level wind shear nearby airports; According to the computational results, the prediction about the location and the intensity of the wind shear can be made out.
分别采用Navier＿Stokes方程和镜像对称的方法,对机场区域附近发生低空风切变时所形成的三维流场进行了数值模拟;并根据结果对风切变发生的位置和强度提供有效的预测。
3) Reflectional symmetry
镜像对称性
4) mirror-image dissymmetry
镜像反对称
5) mirror-symmetric extension
镜像对称延拓
6) single-loop mirror-symmetry
单回路镜像对称
1.
In designing left-handed metamaterials composed of magnetic resonators and electric resonators,two design principles,that is,the single-loop mirror-symmetry design principle and double-loop(quadruple-loop) mirror-symmetry design principle,were respectively proposed for the design of magnetic resonators and electric resonators.
基于这一设计方法,提出了能够抑制双各向异性的磁谐振器和电谐振器设计原理,即单回路镜像对称设计原理和双(四)回路镜像对称设计原理。
补充资料：对称与非对称
反映客观事物在结构、功能、时空上的特殊联系的范畴。对称指事物以一定的中介进行某种变化时出现的不变性，非对称指事物以一定的中介进行某种变化时出现的可变性。在自然界中普遍存在，形式多样。对称有空间对称(包括形象对称和结构对称)、时间对称、概念对称等。
