摘　　要：通过对比、描述不同材料的拉伸性能测试试样形状,大致归纳拉伸试样形状为柱状和片状结构,分析了2种结构形状在不同材料测试中的适用性,总结了目前在材料领域评判拉伸测试试样结构适用性的几种手段及方法,并且论述了拉伸性能测试在材料科学研究中的重要性。The tensile specimen shapes are roughly induced to columnar and laminar structures by contrasting and describing the shapes of the different material tensile test specimens. The suitability of the two kinds of structural shapes in the different material tests is analyzed. Several means and methods for evaluating the suitability of tensile test specimen structures in the current material fields are summarized. And the importance of the tensile property testing in the material science research is discussed.
