| Abstract: | Bazed on the practice,the paper discusses the basic theory of transition-curve and discusses the computing method of transition-curve,and develops a program for curve with Visual Basic in order to complete the coordinate of any curve-point in the measurement coordinate system.The paper provides convenient integration interface for the designer and the operator,meanwhile,it can improve the precision of point which we need and ensure the validity of the data. |
