太阳温度下７Ｂｅ（ｐ，γ）８Ｂ反应的天体物理Ｓ因子与太阳高能中微子丢失的现象密切相关。迄今为止，直接测量都是在远高于天体物理感兴趣的能区进行的，理论外推不可避免地引入较大的误差。利用７Ｂｅ的单质子拾取反应和渐近归一化系数可以间接导出零能量下７Ｂｅ（ｐ，γ The astrophysical S-factor of the 7Be (p, γ) 8B reaction at solar temperature is closely related to the loss of solar high-energy neutrinos. To date, direct measurements have been carried out far above the energy regions of interest in astrophysics, and theoretical extrapolation inevitably introduces large errors. 7Be single proton pick-up reaction and the asymptotic normalization coefficient can be derived directly under the zero-energy 7Be (p, γ
