由拉曼光谱仪测试巨晶普通辉石及包体中的顽火辉石、透辉石拉曼光谱，描述了谱图的位置、形态和相对强度，分析了振动模式，同时对相应的离子基团如非桥氧Si—O—，桥氧Si—O0，O—Si—O，M—O做了谱带归属。通过不同切片方向的谱带强度相对大小及某些谱带的缺失，初步研究了辉石族矿物晶体结晶学定向问题。

英文摘要：

By testing the Raman spectra of megacryst pyroxene, enstatite and diopside in terms of location, shape and intensity, the syn~rnetries of the main spectral band of pyroxene and the vibration modes of Raman shift were identified. The spectral hands of corresponding ionic groups such as non-bridge oxygen Si- 0 and bridge oxygen Si--O0 , O~Si--O and M--O were assigned for vibrational mode. Through the change in the intensity of the spectral band in different section direction and the deficiency of some spectral bands, the orientation problem in mineral crystallography was preliminarily studied.
