Its graphics is described visually by considering the intersection of the surface with a plane or a concentric cylinder,by which two of its characteristics are pointed out: sine and ruled.

Based on elastic dynamics mechanics,the numerical simulation of guided circumferential wave propagation in hollow cylinder by Matlab programming was achieved.

Analytical solution and numerical simulation of non-Fourier heat conduction models summarizes and comments on predecessors results and obtains the analytical solution of hyperbolic heat conduction model for a hollow cylinder with inner and outer boundary surfaces subjected to sudden temper.

The outside diameter, height and inside diameter of the hollow cylinder can be measured automatically and quickly by the auto measuring system, the non-conformity workpiece can be eliminated, the measured data can be conveyed to the computer, and also can be stored and processed.
