利用电生介子实验测量方法研究夸克-强子二重性,尤其在S~（1/2）=2GeV附近的深度非弹性条件下的单举电子核子散射实验,是验证其共振态二重性最佳的能量区域.本文描述了依据夸克-强子二重性来研究固定靶实验在单举反应中的共振态现象,并描述了利用共振态的数据进行数据分析的方法.计算了介子系统能动量、四动量、散射角等相关参数,同时讨论了实验测量方法,从理论与实验的角度说明了北京试验束装置上的固定靶电子散射实验是研究夸克-强子二重性的重要实验数据库.

英文摘要：

It is an important method to study the quark-hadron duality through the mesons produced by electron scattering, and the exclusive electron-nuclei scattering, under deep inelastic scattering at energy region around √S =2 GeV, is optimal for verifying the duality of the resonance state. This paper describes the resonance states of exclusive reaction through fixed target experiments, which is based on quark-hadron duality. The analyzing method using data from the resonance states is introduced. The characteristics of the mesons system have been calculated, including the four-momentum and scattering angle, and the experimental method is also discussed. In conclusion, it is demonstrated, theoretically and experimentally, that the fixed target electron scattering equipment on Beijing test-beam line is an important database to study the quark-hadron duality.
