Abstract: A microspheric ionomer having a cross-linked structure, a preparation method therefor, applications thereof, and a preparation system thereof. The ionomer comprises structure units A represented by formula (1), structure units B represented by formula (2), and a cross-linking structure provided by a cross-linking agent, M being separately selected from H, a metal cation, and a straight chain, a saturated alkyl of branched or ring-shaped C1-C20, R being H or a methyl; and metal cations are introduced to part of structure units A in the ionomer. The ionomer shows an outstanding effect on nucleation of PET, serves as a nucleating agent for PET modification, so as to obtain a corresponding PET composition.

Abstract: A method and apparatus for recognizing a text sequence, and a storage medium are provided. The method includes: an image to be processed containing a text sequence is acquired; and the text sequence in the image to be processed is recognized according to a recognition network to obtain multiple single characters constituting the text sequence, and character parallel processing is performed on the multiple single characters to obtain a recognition result.
