摘要：
Effects of homogeneous irradiation of electron beam on bending strength were studied for alkali free glass. The irradiation, which was one of short-time treatments, enhanced the bending elasticity, as well as increased the bending strength, although the irradiation doesn't largely change the fracture strain. Enhancements of bending elasticity and bending strength can be explained by stabilization of atomic distance induced by nano-scopic stress relaxation, which was probably generated by optimum distribution of dangling bonds.
