She is the winner of the National Book Critic Circle Award, the Pulitzer for Fiction and many other literary awards. She was granted the Nobel Prize for literature in 1993, thus becoming the first A^can-American writer to receive this honor. Her first novel The Bluest Eye （1970） tells the story of the bitter and tragic experience suffered by Pecola, a little black girl, and loss of black people＇s self-respect, confidence, value, and culture. The present paper, first of all, gives a brief introduction of the story Then the paper explores the root causes of Pecola＇s tragedy from two aspects： The cause of racial oppression and self-hatred, and the cause of the loss in her independent consciousness. The paper concludes that Pecola is the victim and scapegoat of racial oppression, self-hatred and the loss of her independent consciousness existing in the black community展开更多

Despite its natural resistance to the slow drift of reference frames, the performance of practical RFI-MDI-QKD systems descends with the increasing drift of reference frames. In this paper, we demonstrate the worst relative rotation of reference frames for practical RFI-MDI-QKD systems, and investigate their performance against the worst-case scenario,both of which are unclear to date. Simulation results show that, practical RFI-MDI-QKD systems can achieve quite good performance even against the worst-case scenario, which clearly demonstrates that it is possible to implement practical MDI-QKD systems with freely drifting reference frames.展开更多
