FeO-rich silicates and Ca, Al-rich inclusions in Qingzhen andYamato 691 (EH3) meteorites: Evidence for migration of mass in the solar nebula被引量：1
《Chinese Science Bulletin》2002年第2期150-153,共4页LIN Yangting OUYANG Ziyuan A.EI Goresy 
This work was supported by the National Science Fund for Distinguished Young Scholars (Grant No. 40025311).
The Qingzhen and Yamato 691 (EH3) enstatite chondrites, which formed under extremely reducing condi-tions, are studied using the scanning electron microscope and electron probe microanalyzer. Both meteorites contain F...

Ca-,Al-rich refractory inclusions and Pt-metal nuggets in the Ningqiang carbonaceous chondrite被引量：1
《Chinese Science Bulletin》1999年第8期725-731,共7页A.El Goresy 
Petrography and mineral chemistry of Ca, Al-rich inclusions of Ningqiang carbonaceous chondrite are studied and the highly Re-Os fractionated Pt-metal nuggets in it is discovered. The refractory inclusions are classif...

ON THE YOUNG CRAB-LIKE SNRs AND THEIR STATISTICAL L_x-E RELATION
《Chinese Science Bulletin》1992年第24期2062-2066,共5页陈阳 曲钦岳 汪珍如 
Project supported by the National Natural Science Foundation of China
Crab-like supernova remnants (plerions) are a kind of SNR which has a central neutron star or pulsar. It is generally believed that the central pulsar drives the evolution of the plerion. A statistical relation betwee...

DISCOVERY OF A NEW PLANETARY NEBULA WITH [WC11] CORE STAR: IRAS 19367+2458
《Chinese Science Bulletin》1992年第3期213-216,共4页胡景耀 董怡荪 
Planetary nebulae are the progenetors of white dwarfs in the final evolution stage of stars with intermediate initial mass ( 1M_⊙<M_*<9M_⊙). The planetary nebulae can be devided into different groups according...

THE INTERIOR METRIC APPROACH TO AN AXIS CHARGED AXISYMMETRIC NEBULA——THE ANALYTIC EXACT SOLUTIONS OF EINSTEIN-MAXWELL EQUATIONS
《Chinese Science Bulletin》1991年第21期1778-1782,共5页周启煌 
By use of the general expression of a static axisymmetric metric tensor, the Einstein-Maxwell equations of an axis charged axisymmetric nebula are established under the condition of no pressure. Under the condition th...
