沈约的《四声韵谱》约于唐初亡佚,但清康熙间,杨锡震称得其古本,将其集注并抄赴内阁。因抄本系世上的唯一存本,见者极少,除《(光绪)香山县志》和王士祯的《居易录》有所记载外,未见其他有记载、了解、评介或涉及该书的文献资料。由此,特对沈约《四声韵谱》及亡佚、杨锡震及集注抄本、抄本与吴棫《韵补》和毛奇龄《古今通韵》的异同等问题进行探讨,并提供给读者参考。 Shen about the “four phonetic spectrum” was about lost in the early Tang Dynasty, but during the Qing Emperor Kangxi, Yang Xizhen called its ancient, will focus on and copied to the cabinet. Due to the transcripts of the world’s only depositor, few see, except “(Guangxu) Xiangshan County” and Wang Shizhen’s “Habitat recorded,” there are no records, understand, review or related to the literature data. Therefore, the author discusses the similarities and differences between Shen Yu “Four Phonograms” and the lost, Yang Xizhen and collected transcripts, transcripts and the similarities and differences between Wu Yun’s “Yun Bu” and Mao Qi Ling’s “ancient and modern Tong Yun”.
