中文摘要:

      用差示FT－Raman和^11B NMR光谱学研究了四硼酸锂过饱和溶液的结构机理，结果表明硼酸盐过饱和溶液中存在的粒子有：B（OH）3、B（OH）4^－、B3O3（OH）4^-、B4O5（OH）4^2-和B5O6(OH)4^-，其结构机理类似于四硼酸锂饱和溶液和其他碱金属四硼酸盐溶液的结构机理。

英文摘要:

      Difference FT-Raman and 11B NMR spectra of supersaturated lithium tetraborate solutions were recorded. The spectra shown the presence of boron species B(OH)3、B(OH)4-、B3O3(OH)4-、B4O5(OH)42-, and B5O6(OH)4- in supersaturated solutions. Compared with the spectra of saturated lithium tetraborate and other alkali metal tetraborate solutions at saturation or undersaturation, the same structural mechanism exist.
