摘要：

研究了带电中微子和反中微子在$^{208}$ Pb中引起的深非弹性反应中弱结构函数$F_2(x,Q^2)$和$F_3(x,Q^2)$的核介质效应。计算已在一个理论模型中使用相对论性的核谱函数，其中包括费米运动，绑定和核子关联。我们还考虑了介子和ρ介子云的贡献计算介子核自能的微观模型。使用这些结构函数，微分截面的结果已获得并与CERN混合振荡研究仪器（CHORUS）的数据进行了比较。还得到了$\frac{2F_{i}^{Pb}}{208F_i^D}$、$\frac{4F_{i}^{Pb}}{208F_i^{He}}$、$\frac{12F_{i}^{Pb}}{208F_i^C}$、$\frac{16F_{i}^{Pb}}{208F_i^O}$和$\frac{56F_{i}^{Pb}}{208F_i^{Fe}}$（i= 2，3）比值的结果，其中一些与某些唯象拟合进行了比较。

英文摘要：

Nuclear-medium effects in the weak structure functions $F_2(x,Q^2)$ and $F_3(x,Q^2)$ in the charged current neutrino and antineutrino induced deep inelastic reactions in $^{208}$Pb have been studied. The calculations have been performed in a theoretical model using relativistic nuclear spectral functions which incorporate Fermi motion, binding and nucleon correlations. We also consider the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. Using these structure functions, the results for the differential cross section have been obtained and compared with the CERN Hybrid Oscillation Research apparatUS (CHORUS) data. The results for the ratios $\frac{2F_{i}^{Pb}}{208F_i^D}$, $\frac{4F_{i}^{Pb}}{208F_i^{He}}$, $\frac{12F_{i}^{Pb}}{208F_i^C}$, $\frac{16F_{i}^{Pb}}{208F_i^O}$, and $\frac{56F_{i}^{Pb}}{208F_i^{Fe}}$ (i=2,3) have also been obtained and a few have been compared with some of the phenomenological fits.
