Based on a detailed analysis of the Chinese ancient record of the BC 48 guest star and the new detected physical parameters of PSR J1833-1034, agreements on the visual position, age and distance between PSR J1833- 1034 and the BC 48 guest star are obtained. The initial period/90 of PSR J1833-1034 is now derived from its historical and current observed data without any other extra assumption on P0 itself, except that the factor PP is a constant in its evolution until now.展开更多

The major claim of the paper is that certain dimensions of Tangut Buddhism are traceable to their Sinitic parental tradition, the Buddhism in the Tangut Empire evolved in a specific manner, which was influenced by the Buddhism of the Liao Empire. This implies that Sinitic Buddhism in Xixia was modeled according to the model ＂perfect teaching,＂ promoted by the Liao Buddhists. Thus, the approach basedon the traditional ＂school＂ （including ＂Chan School＂） paradigm is inappropriate for the study of Tangut Buddhism. In this stead I am suggesting a ＂perfect＂ approach, which allows grouping the available texts on the basis of their position in the scheme of the ＂perfect teaching＂ and explores the contents of these texts from this angle. Thus, the specific nature of the texts traditionally deemed as Chan in the Tangut Buddhist system is seen in their relationship to the ultimate practice of the ＂contemplation of the Dharma realm.＂ Finally, the paper introduces some new translations from Tangut.展开更多

文摘Stimulated by the recent discovery of PSR J1833-1034 in SNR G21.5-0.9 and its age parameters presented by two groups of discovery, we demonstrate that the PSR J1833- 1034 was born 2053 years ago from a supernova explosion, the BC 48 guest star observed in the Western Han （Early Han） Dynasty by ancient Chinese.

文摘The paper is an attempt to generalize the results of the previous schol- arship concerning the nature and specific features of Sinitic Buddhism in the Tangut Empire. The major claim of the paper is that certain dimensions of Tangut Buddhism are traceable to their Sinitic parental tradition, the Buddhism in the Tangut Empire evolved in a specific manner, which was influenced by the Buddhism of the Liao Empire. This implies that Sinitic Buddhism in Xixia was modeled according to the model ＂perfect teaching,＂ promoted by the Liao Buddhists. Thus, the approach basedon the traditional ＂school＂ （including ＂Chan School＂） paradigm is inappropriate for the study of Tangut Buddhism. In this stead I am suggesting a ＂perfect＂ approach, which allows grouping the available texts on the basis of their position in the scheme of the ＂perfect teaching＂ and explores the contents of these texts from this angle.
