Problems related to gauge invariance,Lorentz covariance and canonical quantization applied in nucleon structure study

摘要：

Outline 1.Introduction 2.Gauge theory without gauge interaction 3.Gauge invariant decomposition 4.Physical meaning of parton distribution and its evolution 5.What is the key issue of nucleon structure study Ⅰ.Introduction Nucleon is an SU(3) color gauge system,atom is an U(1) em gauge system.The mass(energy)-momentum,spin,orbital angular momentum distribution among the constituents are fundamental problems in the internal structure study of atom and nucleon.
