Mental health, health-related quality of life, and lung function after hospital discharge in healthcare workers with severe COVID-19: a cohort study from China

Abstract: Coronavirus disease 2019 (COVID-19) is an acute respiratory infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. It is highly contagious and can cause death in severe cases. As reported by the World Health Organization (WHO), as of 6:36 pm Central European Summer Time (CEST), 12 August 2022, there had been 585 950 285 confirmed cases of COVID-19, including 6 425 422 deaths (WHO, 2022).

概要:临近空间高超声速飞行器是指在临近空间能够以大于5马赫速度飞行的一类飞行器,具有飞行速度快、突防能力强、作战半径大和响应迅速等特点。凭借其优异的性能优势,高超声速飞行器逐渐成为各个国家新的空天博弈焦点,给现有防御体系带来巨大挑战。为满足临近空间高超声速飞行器防御需求,本文系统性地梳理高超声速飞行器的"五大优势"及拦截高超声速飞行器的"四大难点"。其次,针对现阶段高超声速飞行器拦截制导律,对基于单弹制导律和多弹协同制导律进行综述,并归纳其优缺点。最后,从"信息域"、"空间域"、"物理域"和"效费比"四个方面对协同拦截高超声速飞行器未来发展方向进行了展望,为临近空间拦截制导技术研究提供参考。
