英文摘要	在金刚石压腔中,硅油作为传压介质,红宝石作为压标,在298.1 K,0.1~5 140.2 MPa下对硅油C—H伸缩振动ν2 906和ν2 967进行了拉曼光谱的原位测量。实验结果表明:在实验压力范围内,硅油ν2 906和ν2 967的拉曼位移与压力具有良好的线性关系。此外,探讨了在实验条件内利用压力介质硅油ν2 906和ν2 967的拉曼位移作为压力计的可行性,并且得到了硅油在298.1 K下的压力标定公式:p=0.14[(Δνp)2 906]2+81.92(Δνp)2 906+92.01,R2=0.99和p=-0.05[(Δνp)2 967]2+73.07(Δνp)2 967+91.54,...; Within a diamond-anvil cell, the in-situ Raman spectroscopic study of silicone fluid was operated at room temperature 298. 1 K and under pressures from 0. 1 to 5 140. 2 MPa. The present study analyzed the correlation of the modes 2 906 and 2 967 cm(-1) with different pressures, indicating that their wavenumbers linearly increased with increasing pressure. Therefore, this provided the potential to consider the pressure medium silicone fluid as a pressure gauge. The result suggested that silicone fluid could be used as a reliable pressure gauge in high-pressure experiments using diamond-anvil cells with Raman spectrometer, and the correlations between pressure and (Delta nu(p))(2 906), (Delta nu(p))(2) (967) are, p=-0.05[(Delta nu(p))(2 967)](2) + 73.07(Delta nu(p))(2 967) + 91.54 and p=0.14 [(Delta nu(p))(2 906)](2) + 81.09(Delta nu(p))(2 906) + 92.01, respectively.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000281661000020&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; PubMed; 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); 1; 09; 2390-2392; 30
