twist motion

In this paper we calculate the normalization constants mp_ 0 π and mp_ 0K of the twist-3 distribution amplitudes of the pion and kaon from the QCD sum rules, instead of using the equations of motion.

用QCD求和规则计算了π介子和K介子的两个twist3分布振幅的归一化常数mp0π和mp0K。

This model provides theoretical basis for further study on the motion rules of the convergence point and controlling stability and reliability of self twist spinning process.

此模型对于进一步研究自捻纱线在汇合点的运动规律，控制自捻纺纱过程的稳定性和可靠性提供了理论基础。
