The 'big bump' is one of the most striking features of the spectral energy distribution of quasars. It extends from optical light to EUV and soft X-ray. It has been suggested that this is due to the thermal radiation from an accretion disk within tens of Schwarzschild radii from a black hole However, McDowell et al. revealed a few quasars with a

Dear Editor,Chikungunya virus(CHIKV),an arbovirus in the family of Togaviridae,genus Alphavirus,is transmitted by the *** or *** mosquito,and causes disease in humans characterized by fever,rash,and arthralgia(Silva and Dermody 2017;Suhrbier 2019).It was first reported in 1953 in Tanzania,and caused only a few outbreaks and sporadic cases in Africa and Asia in last ***,in the epidemic in 2004,CHIKV acquired mutations that conferred enhanced transmission by the *** mosquito(Schuffenecker et al.2006).Since then,it has successively caused outbreaks in Africa,the Indian Ocean,South East Asia,the South America,and Europe(Zeller et al.2016).

Through engineering education, a set of didactical programs and activities are planned to bring the essential knowledge, expertise and training to the students from the corresponding discipline and make them gain the competence of coping with various professional problems independently. Although holding the same views on the importance of developing competence, china and Germany construct the respective education systems in consideration of the different circumstances. In this paper, we propose the analysis onto the engineering education systems in the two countries and characterize the systems as competence-oriented. Through reflecting the differences, we mainly propose three suggestions as the theoretical contribution for deriving advantages from the German engineering education system.
