民航CT安检设备技术性能检测与评估研究
|
摘要
随着反恐形势的变化和科学技术的发展,X射线计算机断层成像安全检查设备在民用航空安保领域得到越来越多的应用,具有较大的市场潜力,全面开展此类设备的检测与技术性能评估工作刻不容缓。本文针对民航旅客行李安全检查的特点进行理论分析和计算,确立了X射线计算机断层成像安检设备技术参数要求,为建立检测评估标准奠定了基础。
With the ever-changing domestic and international security situations and development of scientific technology,more and more X-ray Computed Tomography security inspection equipments are used in civil aviation.Therefore,it's practically crucial to develop the test and evaluation method for this kind of security inspection equipment.Based on the characteristics of civil aviation passenger's baggage checking,this paper analyzed and calculated the parameters of Computed Tomography security inspection equipment,and described the test methods and evaluation.Such efforts should be made to promote and expedite the development of security equipments for security check.
