In flat ballas the D-band is smaller and the graphite peak larger than in coarse ballas.
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。
These lamella appear to be of graphitic nature since Raman spectra show a sharp graphite peak at about 1585 cm-1 when lamellae are present.
这些薄层好象具有石墨性质，因为当薄层出现时，拉曼光谱在大约1585cm - 1处显示出一个锐利的石墨峰。
The Raman spectra either did not show the diamond 1332 cm-1 peak or the peak was very weak, while the D-band and the graphite peak appeared clearly.
拉曼光谱要么不显示金刚石1332cm - 1峰，要么显示的峰很弱。但D带和石墨峰值却清晰可见。
Using the optical temperature control accessory, silica peak height signal was enhanced doubly, reducing atomization time, extending useful time of graphite tube.
利用光学温度控制器使测量硅的峰高信号增强一倍，试验了时间常数、载气流量、常用酸和盐对测硅灵敏度的影响；
