动力学演化(GLR)方程是小x物理学的一个基本的动力学方程,特别是对于分析HERA的轻子和强子的非弹性散射实验结果以及核内的EMC效应是非常重要的.但是,GLR方程一个严重缺陷就是违背动量守恒.讨论了动量守恒对GLR方程修正的意义,并且指出对实验结果做分析时须注意影响.The GLR equations are the basic equations describing the phenomena in the small x region.Especially it is important to use them for analysing the deep-inelastic lepton-proton scattering and EMC effect.But GLR equations have the defect that they violate the law of conservation of momentum.We discuss this problem and point out the defect in analysing the experiment.
