On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.

通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究，可以得出以下结论：(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动，同时高频区(850-1300cm〓)不断变窄且向低频区方向移动，这表明随着压力升高T-O-T键角不断减小，并且分布范围变窄，T-O-T键角这种变化从而可使T-O键的力常数减小，导致键强减弱；另外，580cm〓谱峰强度随着压力升高不断减弱，并在0.8-1.0GPa时最为显著，这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。
