The gas must be far hotter than the dense matter at the centre of the sun for fusion to happen.

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。

It is also a unique laboratory for studies in several other fields, ranging from the equation of state of super-dense matter to magneto-hydro dynamics.

它同样是研究其他领域如超致密物质从平衡状态到磁流体的独特实验室。

While particulate matter emitted by vehicles make up a small part of overall particulate matter in China, in dense urban areas, it is almost certainly the highest contributor to human exposure of PM2.5, according to Vance Wagner, a senior researcher at the International Council on Clean Transportation.

It depends on a recent body of work which suggests that the brain's white matter (the wiring that connects the main bodies of the nerve cells, or grey matter, together) is less dense and less abundant in the brain of an autistic person than in that of a non-autist.
