【摘要】 讨论了影响拉伸试验结果的因素，着重分析了加载条件试样几何以及试验刚度可能引起误差的原因。指出注意试验条件是控制试验结果准确的关键。在简单拉伸试验中常常会引入一些附加的应力，一般照常规方法计算得到的强度要小于真实存在的强度。更多还原

【Abstract】 In this paper, factors influencing on experimental results are discussed. Loading conditions, shapes and sizes of samples and rigidity samles possibly result in probable errors. Attaching importance to text conditions is a key to precision. In the tensile test, extra stresses sometimes would be made. In this case, the strength is smaller than real strength, if calculated by notmal methods.更多还原
