Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.
恒星核心中发生的核聚变产生热能与向外的压力，不过这份压力由恒星质量所产生的内向重力抵消了。

But most stars are not massive enough to create the pressures and heat necessary to burn heavy elements, so fusion and heat production stop.
