【摘要】 报道了利用光学频谱分析系统对注射针尖进行质量检验的实验,给出了测!数据统计处理方法。实验结果表明,对针尖尖锐度的检测已达到针尖曲率半径之极限范围,对于针尖平度数a>0.02毫米的次品针尖检出率η>94.5％。更多还原

【Abstract】 Inspection of hypodermic syringe needle tips has been performed in our lab using an optical spectrum analysis system. The statistic processing method realized by a digitial computer is presented. The experimental results indicate that the minimal measurable defect size of damaged needle tips approaches the curvature radius of normal needle tips. When the defect size a is over 0.02mm, inspection ratio η is greater than 94.5%.更多还原
