摘要：Small and medium-sized modular reactors normally are reactors whose power usually less than 300 MW,also,the primary circuit loop such as core,heat exchanger,pump are integrated in the pressure vessel,due to its integration and lower power,the small modular reactor could under the standardized assembly line production and then transported to the destination,in addition,because of the lower power and characteristic of LBE,the LBE cooled small fast reactor could realize natural circulation and then have inherent ***,the small fast reactor could get flexible application such as centralized heating,water desalination and power supply for remote area and marine or space *** view of those,small and medium-sized modular reactors have been a hot area of research these years.

摘要：The glass case is lined by dozens of palm-sized miniature beds-but not the warm,supportive kind that invites a good night’s ***,twisted together from charred copper coils the artist found in electronic repair shops in the 1990s,these bed frames look rugged and even *** is entangled with a wdld web of silk and,occasionally,a cocoon that serves as both the occupant’s cradle and coffin.

摘要：Supported by the National Natural Science Foundation of China,*** Jianlin and *** Wenbo(Shanghai Institutes of Ceramics,Chinese Academy of Sciences)recently reported the design and synthesis of imaging contrast agents,and their early diagnosis for major diseases,which has been published in Advanced Materials(2014,26(23):3867—72)and ACS Nano(2014,8(2):1231—42).
