使用模型计算的基础上的自洽处理的日冕能量平衡，我们展示了如何磁通量管发散率控制的日冕温度和太阳风的属性。对于一个固定的机械和阿尔芬波能量在日冕底部的输入，我们发现，随着发散率的增加，最高日冕温度降低，但离开太阳的质量流量逐渐增加。结果表明，在太阳附近，渐近风速随膨胀因子的增加而减小，这与经验研究一致
Using model calculations based on a self-consistent treatment of the coronal energy balance, we show how the magnetic flux-tube divergence rate controls the coronal temperature and the properties of the solar wind. For a fixed input of mechanical and Alfven-wave energy at the coronal base, we find that as the divergence rate increases, the maximum coronal temperature decreases but the mass flux leaving the Sun gradually increases. As a result, the asymptotic wind speed decreases with increasing expansion factor near the Sun, in agreement with empirical studies
