| 摘 要： | 使用投影法计算了α谱仪探测器和面源不同轴情况下的几何因子，并与实验结果进行了比较。结果表明，不同轴距情况下，α谱仪探测器和面源的几何因子与实验测量结果差异基本一致，对α谱仪刻度和实际测量时几何位置引起的不确定度的评估有参考价值。

| Abstract: | A geometric factor was calculated using projection method on condition for α detector and surface source being not coaxial, and compared with experimental result. The differences between the geometric factor and experimental result are mainly consistent. The study is beneficial to α spectrometer calibration and uncertainty evaluation result from the geometric position in the routine measurement. |
