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。

After dense matter from an imploded white hole hits Earth, the planet's rotation is devastated.

后从一个白色孔致密物质爆炸袭击地球，地球的自转是破坏。

The physical body is dense matter that is visible to the eye and that means that the particles are vibrating at a slow rate.

身体的密度很大可以被肉眼所见，意味着能量微粒以很低的频率在震动。

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.
