摘要
利用热液金刚石压腔研究了白云石在温度298K、压力100～1000MPa下C-O键弯曲振动峰V1097的拉曼变化特征。结果表明，在实验的压力范围内白云石稳定，其拉曼位移和压力具有很好的线性关系，拟合后得出压力与白云石1097cm^-1拉曼线频率位移的关系为：P=143．47（△vp）1097＋102．67（1097〈vp〈1103）。因此白云石非常适合作为热液金刚石压腔的压标。
The variation characters of Raman spectra of C--O band-liberation peak v1097 of dolomite at the experiment pressure of 100 - 1000 MPa and temperature of 298 K were studied using hydrothermal diamond anvil cell （HDAC）. The results show that dolomite is stable under the experimental pressure with good correlation between the Raman peak position shift and the pressure. The relationship between the system pressure and Raman peak position shift of calcite （ 1097 cm^-1） is given as follow： p =143.47（△vp）1097＋102.67 （1097 〈vp 〈1 103） Therefore, dolomite can be used as a pressure gauge for the hydrothennal diamond anvil cell.
