标题： Non-linear screening corrections of stellar nuclear reaction rates and their effects on solar neutrino fluxes

摘要： 在德拜-赫克尔模型的框架下解析计算了恒星核聚变速率的非线性电子屏蔽修正，并将其与萨尔佩特弱屏蔽近似的相应结果进行了比较。 在典型的太阳条件下，偏离萨尔佩特屏蔽因子的程度小于百分之一，而对于温度更高的恒星，在德拜-赫克尔模型的范围内，这种修正仅为百分之一左右。 此外，对所得到的非线性屏蔽效应对太阳中微子通量的影响的研究表明，无论是pp链反应还是CNO链反应，其修正都微不足道。 显示英文摘要

摘要： Non-linear electron screening corrections of stellar nuclear fusion rates are calculated analytically in the framework of the Debye-Huckel model and compared with the respective ones of Salpeter's weak screening approximation. In typical solar conditions, the deviation from Salpeter's screening factor is less than one percent, while for hotter stars such corrections turn out to be of the order of one percent only over the limits of the Debye-Huckel model. Moreover, an investigation of the impact of the derived non-linear screening effects on the solar neutrino fluxes yields insignificant corrections for both the pp and CNO chain reactions.
