Just beneath the surface is the convective zone.

表层的正下方是对流区。

The energy travels outward through a large area called the convective zone.

能量向外通过一大片称为对流区的区域。

When it finally reaches to within 130,000 miles of the surface, the photon enters the convective zone, and the pace suddenly quickens.

当它最终到达距离太阳表面13万英里时，光子进入了对流层，速度突然加快。

Surrounding that is the radiative zone, followed by the convective zone, which extends all the way to the surface.

周围是辐射区，然后是对流区， 一直延伸到地表。
