结果表明，在极化[sup 3]He对极化电子的深度非弹性散射中起相关作用的核效应主要是由[sup 3]He中的[ital S][素数]和[ital D]波产生的有效质子和中子极化引起的。提出了中子[ital g][sub 1][sup [ital n]]和[sup 3]He， [ital g][sub 1][sup 3]自旋结构函数的一个简单可靠的关系式。结果表明，[sup 3]He结构函数的一阶矩的测量可以为Bjorken和规则提供一个重要的检验。
It is shown that the nuclear effects playing a relevant role in deep inelastic scattering of polarized electrons by polarized [sup 3]He are mainly those arising from the effective proton and neutron polarizations generated by the [ital S][prime] and [ital D] waves in [sup 3]He. A simple and reliable equation relating the neutron [ital g][sub 1][sup [ital n]], and [sup 3]He, [ital g][sub 1][sup 3], spin structure functions is proposed. It is shown that the measurment of the first moment of the [sup 3]He structure function can provide a significant check of the Bjorken sum rule.
