Instead of fusion taking place in the stellar core, it fizzles towards the surface.

这时核聚变将在恒星表面发生，而不再是其在核心了。

This was based on the assumption that SMBHs form in a similar way to stellar-mass black holes, marking the final phase in the lifespan of massive stars that have exhausted all their fuel for fusion.

这是以大多超大质量黑洞形成过程与恒星质量的黑洞的形成过程类似的假设为基础的。 这种黑洞的形成通常在大质量恒星的生命过程的最终阶段（用尽了用于核聚变的所有燃料的时期）。

Examples are ionospheres of the Earth and other planets, stellar atmospheres, gaseous discharges for use in various devices and processes, and fusion plasmas in the edge region.

例子在离子层的这地球和其他行星，星体，气体排出物供各种各样设备和过程使用，以及在边缘地区的熔化等离子。

When nuclear fusion uses up a star's fuel, in the central high-pressure stellar core where fusion occurs, the star will collapse fairly violently.
