研究了基于夸克复合机制的高能强子反应中的极化和分析本领。QRC模型用相对论性描述部分子-部分子相互作用，再现了DeGrand和Miettinen的经验规则。我们将QRC模型应用于各种强子产生过程的极化，并通过与实验的比较证明了它的成功。本文讨论了相对论效应在夸克复合过程中的重要性及其对强子反应中自旋极化现象与强子中夸克动量分布的关系。
We study the polarizations and the analyzing powers in high energy inclusive hadron reactions based on the quark recombination (QRC) mechanism. The QRC model repro duces the empirical rule of DeGrand and Miettinen with a relativistic description for the parton-parton interaction. We apply the QRC model to the polarizations of various hadron production processes and demonstrate its success by comparing with experiment. We discuss the importance of relativistic effects in the formulation of the quark recombination process and their significance with regard to spin polarization phenomena in hadron reactions to gether with quark momentum distributions in hadrons.
