论文摘要
$^3he $和$^3H $ nuclei的两极化结构函数是在NLO近似中计算的，考虑到了轻型海夸克对称性破坏和无视。我们在对极化数据和极化dis+Sidis数据的两个分析中提取的细胞核中采用了核子的极化结构函数。由于第二个分析的数据涵盖了Bjorken变量的范围更大，因此在分析中考虑了SU（2）和SU（3）对称性破裂。然后，我们计算和比较从两种情况下提取的核的极化结构。同样，Bjorken和ELT总和是使用结构函数矩计算得出的。将结果与实验数据进行了比较，并研究了差异。
The polarized structure functions of $^3He$ and $^3H$ nuclei are calculated in NLO approximation, considering and disregarding the light sea quark symmetry breaking. We employ the polarized structure function of the nucleons within the nucleus extracted from our two recent analysis on polarized DIS data and on polarized DIS+SIDIS data. Since the data of the second analysis cover a bigger range of Bjorken variable, both SU(2) and SU(3) symmetry breaking is considered within the analysis. Then we calculate and compare the polarized structures of nuclei extracted from both scenarios. Also the Bjorken and ELT sum rules are calculated using the moments of structure functions. The results are compared with experimental data and the differences are investigated.
