就一切情况而论，拉曼光谱明显反映了半刚石的形成。
In all cases Raman spectra showed clearly the formation of the ballas diamond.
在扁平的半刚石中，D带较小，而石墨峰比粗大的半刚石中的要大。
In flat ballas the D-band is smaller and the graphite peak larger than in coarse ballas.
必须注意的是，拉曼强度(背景)因形貌从多面金刚石变成半刚石而得到明显的提高。
It must be noted that the Raman intensity (background) increases strongly due to the morphological change from faceted to ballas diamond.
