The analytical determination of the solid angle subtended by a circular detector for a line source in a parallel plane, whose midpoint is co-axial with the detector's center, is of some relevance to the medical and nuclear power fields. No report has been found in the literature of a closed-form solution to this problem. We present a first principles solution to the problem along with a graph, which gives some indication of the behavior of the derived expression.
对于位于平行平面中的线源，由圆形探测器所张立体角的解析确定具有一定相关性，该线源的中点与探测器中心同轴，这在医学和核电领域中都有一定意义。在文献中尚未发现关于此问题的封闭形式解的报道。我们给出了该问题的第一性原理解答以及一张图表，该图表给出了导出表达式特性的一些指示。
