英文摘要	Very recently, the BESIII Collaboration reported a charged hidden-charm structure with strangeness in the recoil mass of K+ of a process e+e--> Ds-D0K+ or Ds-D0K+, which is named as Zcs(3985)-. The newly observed charged structure can be treated as a partner structure with strangeness of well-known Zc(3885)- reported in a process e+e--> D-D0 pi+. In this work, we propose a reflection picture to understand the nature of Zcs(3985). By performing a combined analysis for the line shape of the recoil mass distribution of K+ at five energy points s=4.628,4.641,4.661,4.681,4.698 GeV, we find that the Zcs(3985) can be explained as a reflection structure of charmed-strange meson Ds2(2573), which is produced from the open-charm decay of Y(4660) with a Ds meson. Furthermore, we predicted the angular distribution of final state Ds- in process e+e--> Ds-D0K+ based on our proposed reaction mechanism, which may be an essential criterion to test the non-resonant nature of Zcs(3985) further.
