摘要

<正>In the report we study the structure of the spinor field in Chiral Soliton Model. 40 years and more ago, Skyrme proposed that the Meson-field configuration carries a topological charge which is interpreted as baryon number. The baryon number current can be interpreted as the topological current. Witten showed that baryon many be described as soliton of pion field. The topological current is defined by
