centre of curvature

中文含义：曲线的曲率中心

英语词性：noun

美式音标： /ˈsɛn.tər əv ˌkɝː.vəˈtjʊr/

同义词：curvature center, radius of curvature center

易混淆单词：center of gravity, center of mass

双语例句：

  • The center of curvature of a lens is usually located in the optical system of a microscope or a telescope. （透镜的曲率中心通常在显微镜或望远镜的光学系统中）
  • The center of curvature of a concave mirror is usually located in front of the mirror. （凹面镜的曲率中心通常在镜前）
  • The curvature of a circle at any point is equal to the reciprocal of the radius of curvature at that point, and the center of curvature is the center of the circle. （圆的任意一点的曲率等于该点的曲率半径的倒数，曲率中心就是圆心。）
  • In order to find the center of curvature of a convex mirror, you need to extend the reflected ray from the mirror back to its original direction. （为了找到凸面镜的曲率中心，你需要将反射光线从镜子上反射回原来的方向。）
