本文以钢的试验数据为基础,分析了在工业X射线照相探伤中电压和焦距的选取对射线照相灵敏度的影响,计算结果指出存在最佳的电压和焦距组合,选取这样的组合进行射线照相可以得到最佳的射线照相灵敏度。
Based on the experimental data of steel, this paper analyzes the influence of voltage and focal length on radiographic sensitivity in industrial X-ray radiographic flaw detection. The calculation results show that there is the best combination of voltage and focal length. Get the best radiographic sensitivity.
