| 摘 要： | 本文用边界元法对销钉接触角及销钉孔半径对三种电流输入方式下紧凑拉伸试样的电位函数影响进行了分析。结果证明,人们在电位法测试中常用的电流输入方式容易引起误差,并非最佳方案.最佳方案是另一种同样方便的电流输入方式.

| Abstract: | The boundary element method is used to analyze the influence of pin con- tact angle and pin-hole radius on the potential function of compact tensile specimen under three current input types.The results show that the optimum type is not these three used types which cause more error but anothcr one. |
