- W987570229 abstract "利用水热金刚石压腔研究了高温高压下0.0%、5.0%、10.0%和20.0%的NaCl-H_2O体系的Raman光谱,研究结果发现:对于盐度一定的NaCl-H_2O体系,当压力不变时,水的Raman伸缩谱峰的波数变化量△v_((O-H))随温度的升高而不断增加;当压力不同时,△v_((O-H))随温度的变化关系(偏移斜率S)不受压力的影响,而只与盐度相关.利用该性质可以用来确定流体包裹体的盐度(W),其计算公式如下:W=123.25S~2-128.11S+32.40,误差为0.46%. Abstract： Raman spectra of different salinities (0.0%, 5.0%, 10.0% and 20.0%) of the NaCl-H_2O systems is studied at high pressure and high temperature using hydrothermal diamond-anvil cell (HDAC). It is shown that the frequency shift (△v_((O-H)) of Raman band in the region of OH stretching vibration increases with increasing temperature at a given pressure for the same salinity of NaCl-H_2O system; at different pressures, the relationship between △v_((O-H)) and temperature is influenceded by the salinity, not the pressure. This property has an important application on the determination of the salinity of fluid inclusion, and the calculated equation is described by: W=123.25S~2-128.11S+32.40, the uncertainty is 0.46%." @default.
