简介:摘要疫苗上市后安全性监测是及时发现风险信号以确保疫苗安全的必要措施,包括被动监测与主动监测。其中,主动监测能够全面、持续的收集免疫接种后不良事件,及时发现并验证疫苗安全性信号,已经成为未来上市后安全性监测的主要发展趋势。随着信息时代的到来,主动监测可通过纵向链接多源电子医疗数据库开展分析,数据的快速传输与定期更新,使得接近实时的发现疫苗安全性信号成为可能,这种主动、及时、快速识别免疫接种后不良事件的准实时主动监测方法逐渐在国际上兴起。本文通过梳理既往文献,对目前疫苗准实时主动监测的发展现状与方法学原理进行综述,以期为我国开展疫苗安全性的准实时主动监测提供借鉴。
简介:摘要:飞机装配工艺包含装配顺序、定位方案、工装设计等要素,是影响装配质量、装配周期等指标的重要因素。与一般机械产品相比,飞机对装配准确度与可靠性的要求更高。同时,由于存在机翼、壁板蒙皮、长桁等尺寸大、刚度小的柔性件,飞机装配工艺设计过程更复杂,考虑因素更多。为保证装配过程中偏差满足质量要求,需在装配前对制造偏差、夹具定位偏差、装配变形等偏差源进行分析,完成偏差预测及优化,进而实现对装配质量问题的主动预防。面对复杂多变的装配现场,即使在设计阶段考虑多种偏差源,工艺仿真结果与现实情况仍会存在差异,不利于装配质量的提升。本文主要分析飞机装配质量主动实时控制技术研究现状与发展趋势。
