使用测量的太阳p-模式的频率,在太阳的信封中的氦的分数质量含量确定。发现其值在0.23和0.24之间。这一结果似乎不受大气和外对流层处理中的不确定性的影响,但它以一种敏感的方式依赖于物理量的计算
Using measured frequencies of the solar p-modes, the fractional mass content of helium in the Sun's envelope is determined. It is found that its value lies between 0.23 and 0.24. This result appears to be unaffected by the uncertainties in the treatment of the atmosphere and the outer convective zone, but it relies in a sensitive way on calculation of thermodynamical quantities
