nuclear transition
1.Because of the inherent flexibility of nuclear fuel cycle in CANDU reactor, the transition from the nature uranium to the recycled uranium(RU) can be completed without any changes of the structure of reactor core and operation mode.
2.After the introduction of the investigative background about the hybrid stars as well as the related astrophysics problems, we describe the EOS of normal nuclear and strange quark matter,then by using Baym-Pethick-Sutherland model describing subnuclear densities,relativistic mean field theory describing nuclear densities and also effective mass bag model considering medium effects for quark matter,we discuss the phase transition in neutron stars,and finally obtain the EOS of hybrid stars.
3.CdSe, a II-VI compound with direct transition, wide-band-gap and high atomic number (48,34), is regarded as a new effective materials for room temperature nuclear radiation detectors and photoconductive devices, and can be used in many fields.
