Hepatitis C virus(HCV), an enveloped positive-sense single-stranded RNA virus, can cause chronic and end-stage liver diseases. Approximately 185 million people worldwide are infected with HCV. Tremendous progress has been achieved in the therapeutics of chronic hepatitis C thanks to the development of direct-acting antiviral agents(DAAs), but the worldwide use of these highly efective DAAs is limited due to their high treatment cost. In addition, drug-resistance mutations remain a potential problem as DAAs are becoming a standard therapy for chronic hepatitis C. Unfortunately, no vaccine is available for preventing new HCV infection. herefore, HCV still imposes a big threat to human public health, and the worldwide eradication of HCV is critically dependent on an efective HCV vaccine. In this review, we summarize recent progresses on HCV vaccine development and present our views on the rationale and strategy to develop an efective HCV vaccine.

【目的】准格尔煤燃烧后灰渣中Al_(2)O_(3)含量超过45%,具有重要的资源综合利用价值。为解决传统循环流化床锅炉燃用准格尔煤时飞灰活性差、Al_(2)O_(3)提取效率低等问题,提出采用水煤浆循环流化床燃烧方式改善灰渣特性。【方法】利用3 MW循环流化床燃烧试验台研究了给料方式、运行氧量、床温、一次风率等对飞灰可燃物含量的影响,并利用比表面积及孔径测定仪、扫描电镜、X射线荧光光谱仪,X射线衍射仪等对不同粒径飞灰成分和微观形貌进行分析。【结果】结果表明:随着床温、运行氧量、一次风率的增加,飞灰可燃物含量逐渐减小;水煤浆粒化燃烧的飞灰可燃物含量明显低于未粒化。飞灰中可燃物主要存在于40μm以下颗粒,随着飞灰粒径的减小,可燃物含量逐渐增加;小颗粒飞灰大部分是由孔隙结构不发达的颗粒构成,可燃物含量较高;随着飞灰粒径的增大,飞灰比表面积和总孔容逐渐减小,平均孔径逐渐增大,粒化末煤浆的总孔容和平均孔径要小于精煤浆;对灰样进行成分分析,发现随着粒径的减小,Al_(2)O_(3)的含量逐渐增大,15μm以下粒径段飞灰中Al_(2)O_(3)的含量达到51.77%;对灰样进行物相检索和半定量分析,活性较好的γ-Al_(2)O_(3)峰随着粒径的增大逐渐减弱,莫来石含量随着粒径的增大逐渐增加,使飞灰的提铝效率降低。总体来看,粒径小于50μm的飞灰中Al_(2)O_(3)的含量更高同时莫来石含量更少,更适合作为提铝工艺原料。

Chinese Physics B 2018年第11期27卷 575-580页

We propose a theoretical model to detect the quantum phase transition in a triangular quantum dot molecule with frustration. The boundaries of the phase diagram are accurately determined by the transmission. For small frustration t, as the interdot Coulomb repulsion V increases, the system undergoes a Kosterlitz–Thouless（KT） transition from the Kondo resonance state with a transmission peak at zero energy to the Coulomb blocked state with zero transmission, which is followed by a first transition to the V-induced resonance（VIR） state with unitary transmission. For large frustration t, as V increases, the orbital spin singlet without transmission transits to the VIR state through a KT transition.
