Abstract: Provided are a synchronization method and apparatus for audio and text, a device, and a medium. The method includes: determining a plurality of first text segments for audio conversion and a second text for reading display, in which the plurality of first text segments and the second text are from an initial text; converting the plurality of first text segments into audio segments, to obtain a first mapping relationship between the first text segments and the audio segments; performing matching on the first text segments and the second text, to obtain a second mapping relationship between the first text segments and second text segments in the second text; determining the second text segment synchronized with each of the audio segments based on the first mapping relationship and the second mapping relationship.

Abstract: Embodiments of the present disclosure disclose a method and device for planning a wall surface polishing path, an apparatus and medium.

Abstract: The present invention relates to a group of derivatives synthesized based on the ent-kaurane diterpenoid flexicaulin A and the methods to synthesize such diterpenoid derivatives. In particular, the chemical entities of such synthetic diterpene compounds in the manufacture of a medicament is for the treatment of tumors or cancers.
