摘　　要：应用弹性力学和断裂力学的基本原理，分析了颗粒弥散复相陶瓷材料的微观热应力，阐述了颗粒弥散增韧补强的原理，并推导了弥散相的颗粒尺寸和体积分数的临界值，提出了颗粒弥散陶瓷材料设计的一般性原则。Elastic mechanics and fracture mechanics were applied to the analysis of residual thermal stresses of particulate strengthened ceramics. The critical values of particle size and maximum volume fraction of dispersed particulates were derived and some principles in the design of microstructure and the selection of material of dispersed particulates were proposed. This formed a basis for the design of particulate strengthened ceramics.
