摘　　要：本文介绍以先进结构陶瓷为主要对象的脆性材料抗张强度的各种评价方法。包括直接单轴拉伸法和各种间接测定法。Evaluation and testing methods of the tensile strength of advanced structural ceramics as a typical brittle material are briefly summarized in the present paper. General concepts relating to the strength tests of brittle materials are discussed. A variety of uniaxial tensile tests and some of indirect tensional tests including the bend test,the pressurized ring test and the diametrical compressive ring test as well as theta specimen are detailed.
