Abstract：
In the LUND model, the explanations of e⁺e^-→qqg→3jets and Y→3g→h's are based on the application of the LUND string fragmentation model to the color string structures of qqg and 3g systems. In this paper, starting from the color wave functions of the qqg and 3g systems, these color string structure are directly studied by using QCD. It is shown that the reasonableness and accuracy of the LUND string picture are revealed.
