The method of spherical is a new method for calculating a spaceangle.It is an ingenious combination of figures with mathematics.The method can be defined as follows:translate the space line and planeof the object into a spherical the coordinate system,and draw a figure ofsolid sphere by employing.“true exisence”of angular relation in the spher-ical figure.Thus,the required angle can be directly measured in a plottinginstrument of spherical figures,or a plane—spherical figure line the threeplane projection can be drawn.Finally,calculate the angle by using theformulas of the spherical triangle.The research of space lines revolving on any axis at any time is a con-tinuation of the the dynamic research of the method of spherical diagrams,In this paper a description is made of the space line and plane revoluing onany axis at any time according to the theory of the method of sphericaldiagrams.And then,the research of its track and angular coordinate inspherical figure is described.It has been known through the research thatthe moving tracks in the spherical figure are clear and perceivable.The calculation of the angular coordinate is simple and accurate.That fully reflects the advantages of the method of spherical diagrams.
