| Abstract: | This theses studied on the trajectory which came from a point of a movable straight line through any fixed point in space meet certain conditions(these conditions concerned with the point of intersection from fixed-point,movable straight and hyperboloid),this equation of trajectory still expressed a central quadric surface,this theses also elicited a method of the central quadric surface equation that a movable point meet the conditions of the theses was given. |
