本文在手征夸克孤子模型的框架下，在大Nc极限下，研究了手征奇扭3核子分布e（x）在约0.6GeV的低归一化点处的性质.值得注意的结果是，在模型中，e（x）在x=0处包含δ函数型奇点。在模型的低尺度下，发现e（x）的常规部分是相当大的，并且与袋模型计算的定性一致。
The chirally-odd twist-3 nucleon distribution e(x) is studied in the large-Nc limit in the framework of the chiral quark-soliton model at a low normalization point of about 0.6 GeV. The remarkable result is that in the model e(x) contains a delta-function-type singularity at x=0. The regular part of e(x) is found to be sizeable at the low scale of the model and in qualitative agreement with bag model calculations.
