把一个图形绕着某一点旋转180度,如果它能够与另一个图形重合,那么就说这两个图形关于这个点中心对称,这个点叫做对称中心(the point of symmetry),两个图形关于点对称也称中心对称,这两个图形中的对称点,叫做关于中心的对称点。
场线性对称点 VSL ; V-SLOPE
视网膜对称点 corresponding retinal points
不对称点组 unsymmetric point pattern
全对称点群 [数] holohedral point group
不对称点型 [科技] unsymmetric point pattern
对称点扩散函数 centrosymmetric point spread function
对称点群 Symmetry point groups
点对称 [数] point symmetry ; Point of Symmetry
局部对称点 local symmetric points
测量点坐标左右对称点表明的是左侧点坐标,右侧与左侧对称。
The symmetrical points of the coordinates of measurement points indicate coordinates of the points left, and the right and the left are symmetrical.
结果发现由取代引起的非对称点能将严重破坏系统铁磁基态的稳定性。
It is found that the asymmetric site energy, induced by substitutions, will severely weaken the stability of the ferromagnetic ground state.
并进一步构造了与尺度函数对称点一致、系数长度不超过8的所有对称(反对称) 小波滤波器组。
Moreover, all symmetric and antisymmetric wavelets, which have same symmetric point as the scaling function and the length of their filters are no more than 8, are also given.
So let's reflect these two points.
那我们就把这两个点对称过去
