Furthermore, a new mode, high-order Bessel-Gauss mode, is put forward to describe hollow beams. The results for high order Bessel-Gauss beams propagating through lens focusing system and free space are derived by terms of Collins integral formula.

A Material nonlinear finite element analysis for the cast-in-place reinforced concrete hollow slab that occurs from initial loading, cracking, yielding to failing is carried on. The cracking load, ultimate load, the displacement rules and the principal stress distribution rules of the hollow slab under the vertical loads are obtained. A Material nonlinear finite element analysis for the single span hollow flat-plate floor is also carried on. The function of the concealed wide-flat beams is definite by analyzing the principal stress distribution diagram. The calculating results verify the theoretical analysis and give some important conclusions which are great useful to improve the constructing of the new flat-plate floor.

And by using the initial conditions as well as the end conditions, the dynamic problem is then transferred to a second kind Volterra integral equation about the function of the axial strain with respect to time which can also be solved successfully by the interpolation method. For piezoelectric and pyroelectric hollow cylinders, by following the solving procedure for elastic hollow cylinder and by using the electric boundary conditions, the dynamic problems are transferred to two Volterra integral equations about two functions of time, one is axial strain and the other is related to electric displacement, which can also be solved efficiently and quickly by employing interpolation method. The elastodynamic solutions of hollow spheres, which are made of elastic, piezoelectric and pyroelectric materials, respectively, for spherically symmetric problems are also obtained.
