測定了多種礦石標準試件及不同粒度自然礦塊的抗破壞性能，表明自然礦塊的抗壓強度遠小於標準試件，且具有隨粒度減小而增大的趨勢，也說明金屬礦粗磨機球徑計算中採用標準試件抗壓強度代表巖礦破壞性能是不合理的。We also report the uv - visible optical absorption spectra of these colloids. to the metal plate prepared simultaneously, the measurement result of sem and afm of this plate is also reported and the roughness of the silver plate surface is about 60nm. both the colloids and the nano - scale metal surface can become the very perfect sers substrates. rhodamine b, a kind of strong fluorescence laser dye, with gold colloidal surface, has been studied by surface - enhanced raman spectroscopy ( sers ) with near - infrared ( nir ) excitation in the presence of the halide ions ( cf, br -, f )
