周玲棣等,对一些用X射线粉末衍射法确定为正长石的晶体进行了~(29)Si和~(27)Al核磁共振谱研究,发现这些正长石的~(29)Si NMR谱并不象一些人所描述的那样是两个分别占T_2和1/2T_1位置的峰,而具有3个峰。笔者对安徽太平花岗岩岩墙中正长石斑晶的微结构与~(29)Si NMR谱进行了研究,以期对该正长石的~(29)Si NMR谱具有3个峰作出解释。
Zhou Lingdi et al. Studied some ~ (29) Si and ~ (27) Al nuclear magnetic resonance spectra of some of the crystals identified by X-ray powder diffraction as orthoclase and found that the ~ (29) Si NMR spectra of these orthoclase Unlike some people described as two T_2 and 1 / 2T_1 respectively occupy the position of the peak, and has three peaks. The author studied the microstructure and the ~ (29) Si NMR spectrum of the orthoclase feldspar in the Taihang granite dyke wall in Anhui Province in order to explain the three peaks of the ~ (29) Si NMR spectrum of the feldspar.
