The experimental results show that foe values of strain intensity factor and strain fracturetoughness are more stable and useful or determining the thermal fractureproperty of the concrete.
实验表明，作者提出的应变强度因子及应变断裂韧性的概念对反映混凝土材料的断裂特性更稳定更具实际意义。

The results showed that multiple solution and aging treatment had a significant effect on increasing plastic property and fracturetoughness, although had little effect on strength.
结果表明：多重固溶时效热处理可以显著提高合金的塑性和断裂韧度，而对强度的影响不大。
