摘要:在分析国内外相关标准中放大倍数选择的基础上,结合实际应用,对X射线实时成像检测方法中关键工艺参数最佳放大倍数进行了不同倍数情况下的试验、研究与分析,得到了实际生产时的放大倍数应选择在最佳放大倍数以内的结论,因为这样可以得到较高的空间分辨率和较大的检测对比度,为X射线实时成像检测应用中的最佳放大倍数选择提供借鉴。
关键词:X射线实时成像检测;最佳放大倍数;空间分辨率;不清晰度

Abstract:Combine the choosing of best magnification times in domestic and international standards with practical application, we have conducted testing, research and analysis on different magnification times for the study of best magnification, which is one of the critical process parameter for X-ray real time radiography. And these research can be considered as the reference for the choosing of best magnification times during application of X-ray real time radiography and also being concluded that in order to get a higher spatial resolution and larger detection contrast, the magnification times should be no larger than the best magnification times during actual process.
Key words:X-ray real-time radioscopic testing;best magnification;spatial resolution;unsharpness
