英文摘要	实验利用金刚石压腔装置研究了常温和0.1～1400 M Pa范围内黄铜矿A1振动模式的原位拉曼光谱特征。结果显示在实验条件范围内，该拉曼振动峰的强度和形态保持稳定，表明晶格内Cu-S和Fe-S间的相互作用没有发生质变。实验发现黄铜矿该拉曼振动的波数随着压力升高连续向高频方向移动，两者的线性关系为：ν290＝0.0312p＋290.60（0.1≤ p＜58.8 MPa）和ν290＝0.00572p＋292.10（58.8≤ p＜1400 MPa） dν/d p。常温下58.8 M Pa是黄铜矿该拉曼波数随压力变化率的一个突变点，低于和高于该压力时分别为31.2和5.72 cm -1· GPa-1，显著的差异表明黄铜矿的结构可能发生了某种改变。; The variation characters of the A(1) mode Raman spectra of chalcopyrite under 0. 1 similar to 1 400 MPa and ambient temperature were researched using diamond anvil cell. The results show that the shape and intensity of the Raman peak remains constant under experimental conditions, indicating that the chemical bounds of Cu-S and Fe-S remain unchanged. The authors have also noticed that the position of the Raman peak shifts to higher frequency with increasing pressure, which could be described as: nu(290) =0.031 2p+290. 60(0. 1 <= p <= 58. 8 MPa) and nu(290)=0. 005 72p+292. 10(58. 8 <= p<1 400 MPa). The rate of the Raman peak shifting with increasing pressure changed abruptly at about 58. 8 MPa, the dv/dp is 31. 2 and 5. 72 cm(-1) . GPa(-1) below and above 58. 8 MPa respectively, which perhaps indicate that some structural changes occurred in the chalcopyrite.; 国家自然科学基金项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000329379000019&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; xueyinyuan@live.com; hfzheng@pku.edu.cn; 1; 87-91; 34
