There are polarized structure functions $b_{1-4}$ for the spin-1 deuteron. We calculated the leading-twist tensor structure function $b_1$ by using convolution description for the deuteron. We found large differences between our theoretical functions and HERMES experimental data on $b_1$. Although higher-twist effects should be considered in obtaining experimental $b_1$, it suggests a possible existence of new hadron physics mechanism for spin-1 hadrons. Furthermore, we found that there are significant distributions at large Bjorken $x$. In future, an experimental measurement is planned at JLab for $b_1$ and there is a possibility of a proton-deuteron Drell-Yan experiment at Fermilab with the tensor-polarized deuteron, so that further theoretical studies are needed for clarifying the physics origin of tensor structure in terms of quark and gluon degrees of freedom.

Quark-Hadron Picture of the Deuteron Photodisintegration
氘核的高能二体光致蜕变是研究核中夸克效应的理想反应。特别是，在几GeV的区域内研究这一反应，可以阐明从核子自由度到强子QCD图象的转变。TJNAF Hall B的CLAS大角度光谱仪首次允许在实验室框架中测量0.5至3 GeV之间的光子能量的微分截面，在10至140度之间的所有质子角度。显示了对累积的总统计量的30%进行分析的初步结果。这些结果与已有的实验数据符合得很好，并与最近在夸克胶子弦模型框架下导出的氘核光致蜕变截面的计算结果很好地吻合。
