文摘Based on the dynamic governing equation of propagating buckle on a beam on a nonlinear elastic foundation, this paper deals with an important problem of buckle arrest by combining the FEM with a time integration technique. A new conclusion completely different from that by the quasi-static analysis about the buckle arrestor design is drawn. This shows that the inertia of the beam cannot be ignored in the analysis under consideration, especially when the buckle propagation is suddenly stopped by the arrestors.
文摘Surface enhanced Raman spectroscopy (SERS) has been applied to obtain structural information of surface species adsorbed at electrode surface in the electrode potential range of severe hydrogen evolution, which is very difficult to be gained by using most of spectroelectrochemical and conventional electrochemical methods.
