本文研究了非极化正负电子湮灭中包含的{λ}是横向极化的可能性。由于末态相互作用的存在，非极化类时光子碎裂产生包含{λ}超子（或其他重子）的结构函数{ital {cflx F}}（{ital z}，{ital Q}{sup 2}）对非极化正负电子湮灭中的横向{λ}极化有贡献.
The possibility is examined for the inclusive {Lambda} in unpolarized electron-positron annihilation to be transversely polarized. Because of final-state interactions, there exists a novel structure function {ital {cflx F}}({ital z},{ital Q}{sup 2}) for inclusive {Lambda} hyperon (or any other baryons) production from unpolarized timelike photon fragmentation, which makes a contribution to the transverse {Lambda} polarization in unpolarized electron-positron annihilation.
