英文释义

名词 n.
  1. A cycloid; the curve of fastest descent between two points.
    — Let A and B be two fixed points. Then the time it takes a particle to slide under the influence of gravity along some path joining A and B depends on the choice of the path (curve), and hence is a functional. The curve such that the particle takes the least time to go from A to B is called the brachistochrone.
