应用富里叶变换红外谱仪研究了三个含碱绿柱石样（包括原样与热处理样）。将３４３５ｃｍ－１宽吸收带归属于与铁离子成键的水。谱图表明隧道水的大量脱去是在８００℃以上的温度开始的，对于富碱样品，更可能是在１０００℃以后开始。隧道中碱金属离子的阻塞作用是造成绿柱石隧道水难以失去的重要原因。
Three alkali-rich beryl samples (including samples and heat-treated samples) were studied using Fourier transform infrared spectroscopy. The 3435 cm-1 broad absorption band is assigned to water that bonds with iron ions. The spectrogram shows that a large amount of tunnel water removal begins at a temperature above 800 ° C and more likely starts with a base-rich sample after 1000 ° C. The blocking effect of alkali metal ions in the tunnel is an important reason that the beryl tunnel water is hard to be lost.
