摘　　要：本文对海水主要阴离子（SO42-、CO32-和HCO3-）水溶液中的水分子在温度变化下的拉曼散射特性进行了研究,探讨了水分子的振动模式随温度的变化规律和海水阴离子对水的影响。结果显示：随着温度的升高,水的伸缩振动峰逐渐向高频方向移动,拟合特征峰A1和A2强度比值呈下降趋势,表明水分子之间的氢键作用不断减弱,其数量在减少;同种阳离子溶液中不同阴离子对水拉曼峰偏移量影响的强弱顺序为：SO24-〉HCO3-〉CO23-。对探测识别海底热液口的原位物质成分具有重要的指导意义。The investigation of hydrothermal vents is the top topic of the marine geology study recently.This paper detects spectra of sodium sulfate,sodium carbonate and sodium bicarbonate solutions under a series of temperature.The Raman properties of water with temperature increasing and effects of some anions on Raman spectra of water are analyzed.The result shows that Raman shifts of oxyhydrogen bonds are moving toward high wave number while temperature increasing and the intensities ratio between two fit peaks changes,which indicate the hydrogen bond effect is weakening.Effects of anions on anions on Raman spectra of water are in following sequence：SO2-4HCO-3CO2-3.
