摘　　要：性能稳定的"长寿命"石英玻璃是高科技领域的关键材料。论文着重研究石英玻璃体相、表面结构与缺陷对其化学与力学性能稳定性的影响及其机理。研究结果表明,结构与缺陷是影响石英玻璃性能稳定性的主要内在因素。玻璃假想温度越低,体相结构中气泡、颗粒、条纹、羟基、金属杂质离子等缺陷越少,以及表面与亚表面结构缺陷越少,其性能稳定性越高。Long-life silica glass with stable performance was the key material in high-tech fields.In this paper,the influence mechanism of structure and defect on performance stability of silica glass was studied.It was showed that,structure and defects were the main internal factors affecting performance stability of silica glass.The lower fictive temperature of silica glass was,and also the fewer defects in the bulk and surface of silica glass were,the higher performance stability was.
