英文摘要: Within the framework of ungauged and gauged supergravities, we try to construct new exact solutions of rotating charged black holes and black rings. (1) Make a deeper research on the metric ansatze proposed by the applier for the construction of generic non-extremal supergravity black hole solutions, and compare its difference with that of Kerr-Schild form; (2) Do a deeper analysis about the metric structures of the already-known solutions with equal charges, supersymmetric solutions and non-extremal supergravity solutions; (3) Construct the most general rotating AdS black hole with two different charges in D=6,7 supergravities; (4) Construct some new exact solutions to other known supergravity theories; (5) In ungauged supergravity, we study the solutions of black strings, black rings, black lens and black Saturn, and find their new charged generalizations. We shall try to seek for the most general 7-parameter non-extremal solution of the currently unknown black ring (with dipole charges); (6) Find black ring solutions in gauged supergravity, and investigate the D=5 dimensional cases with backgrounds being Godel universe, or Gibbson-Hawking space, Taub-NUT space, and Eguchi-Hanson spaces; (7) Investigate the basic properties of the obtained solutions, etc.
