聚变反应必须控制在磁场内，需要一亿摄氏度的温度。
Requiring temperatures of more than 100 million degrees Celsius, the fusion reactions have to be contained in magnetic fields.
阿尔伯塔大学的天文学家克雷格.汉克在新闻稿中写道，“这颗中子星诞生时表面温度非常之高，以至于在它的表面也可以发生核聚变，并产生了大约10厘米厚的碳质云层。”
This neutron star was born so hot that nuclear fusion happened on its surface, producing a carbon atmosphere just 10 centimeters thick.
要发生聚变，气体的温度必须远远高于太阳中心致密物质的温度。
The gas must be far hotter than the dense matter at the centre of the sun for fusion to happen.
