| 摘 要： | 本文研究了太阳黑子的致冷问题，认为太阳黑子磁场受其流场扰动，形成大量的磁流体波，这种波把太阳黑子的热能转变成波能，以阿尔文速度沿着磁场传播，把能量携带出黑子区域，致使太阳黑子冷却。

| Abstract: | It is suggested in this that: there is a generation of vigorous hydromagnetic waves when the magnetic field is disturbed by the fluid field of the sunspot.In the processes,the thermal energy converted into wave energy of hydromagnetic waves which rapidly propagate out of the sunspot region with Alfven speed along the magnetic field,hence resulting in cooling of the sunspot.It is very effective to keep observed temperature of the sunspot umbra at surface of the photosphere when the component of disturbed velosity normal the magnetic field is only 0.4 km/s. |
