Ce<sup>3+</sup> and Eu<sup>2+</sup> doped and Ce<sup>3+</sup>-Eu<sup>2+</sup> co-doped Sr<sub>2</sub>MgSi<sub>2</sub>O<sub>7</sub> phosphors are prepared via a high-temperature solid-state reaction technique. The synchrotron radiation vacuum ultraviolet-ultraviolet (VUV-UV) excitation and ultraviolet-visible (UV-vis) emission spectra of...

Based on the measured spectra of rail roughness and track structures longitudinal roughness, the rail grinding limit is studied with the help of an established coupled dynamic metro vehicle–track model and a rolling contact fatigue model. The results indicate that metro rail grinding control should be regulated according to corrugation...
