| Abstract: | The trajectory which came from a point of a movable straight through any certain point in space meet certain conditions(these conditions concerned with the point of intersection from fixed-point,movable straight and acentric conicoid) is studied.This equation of trajectory still expressed a acentric conicoid,and elicited a method of the acentric conicoid equation that a movable point meet the conditions of the thesis was given. |
