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

摘要： 非线性电子屏蔽校正的恒星核聚变反应在德拜-休克尔模型框架下进行解析计算，并与萨尔佩特的弱屏蔽近似相应的结果进行比较。 在典型的太阳条件下，偏离萨尔佩特的屏蔽因子小于百分之一，而对于温度更高的恒星，这些校正仅在德拜-休克尔模型的极限范围内达到百分之一的量级。 此外，对所得非线性屏蔽效应影响太阳中微子通量的研究表明，对质子-质子链和碳氮氧链反应的校正都是不显著的。 显示英文摘要

摘要： Non-linear electron screening corrections of stellar nuclear fusion reactions 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.
