circular vibration
5.The wave function expansion method is used to analyze the interaction of blasting seismic wave and the adjacent underground chambers,the stress expression and displacement expression of circular underground chambers under the blasting vibration are deduced,the stress and displacement distribution of surrounding rocks mass are presented under conditions of the different frequency of blasting seismic wave and different rock mass.
7.The vortex-vibration was measured when the towed velocity, dip angle between the circular cylider and flow velocity, and diameter were varied.
8.The augmentation of damping is the key to suppressing structural vibration. To cut down element number for modeling structure with constrained damping layer(CDL) in general FEM software,the whole element method is adopted to solve the extension,bending and torsion vibration of the hollow circular beam with CDL.
9.Laser Raman spectra in the region 450 - 1750cm-1 have been obtained for the circular double-stranded plasmids DNA molecule in an aqueous solution, indicating not only contain those marker peaks of secondary structure as in conventional B-form of DNA, but also present both 854 and 1083 cm-1 diagnostic bands of reflecting the vibration state of deoxyribosyl phosphodiester backbone.
