采用蒙特卡洛方法，研究了铝硼硅酸盐玻璃固化体中硅、硼和铝元素的浸出情况。为了验证模拟结果的准确性，采用全谱直读等离子体发射光谱(ICP-OES)测试了铝硼硅酸盐玻璃固化体浸出液中硅、硼和铝元素的浓度。模拟结果和实验结果都表明，溶液中硅的浓度会达到一定的饱和值，在溶解析出的动态过程中，玻璃表面会形成胶体层，该胶体层产生的阻碍效应会限制硼和铝的溶解。最终各元素都将达到稳定的平衡状态。模拟结果与实验结果符合的很好，定量再现了玻璃固化体的溶解过程。

The Monte-Carlo method was used to research the leaching of silicon,boron and aluminum in the alu-minoborosilicate solidifition.In order to verify the accuracy of the simulation results,the direct reading plasma emission spectroscopy(ICP-OES)was used.The simulation and experimental results both show a saturate of silicon concentration in aluminoborosilicate solidifition.The dissolution-condensation of silicon leads to the for-mation of colloid layer in the surface,which causes a corrosion blocking and limits the release of boron and alu-minum in solution.Each element will eventually reach a stable equilibrium state.The simulation results agree well with the experimental results.It was possible to reproduce quantitatively the reaction of the glass dissolu-tion.
