而根据这个状态，不是随时间而越来越弯曲，它所拥有的物质与能量必须在一个临界的，特别的密度。
For it to be held that way, rather than getting more and more curved over time, the amount of matter and energy it contains must be at a particular, critical density.
同时，大型强子对撞机仍在开动状态，但只有它最大能量的一半。大型离子对撞机实验的研究小组希望随着对撞机能量的增加能在将来制造出密度再大些的夸克胶子等离子体。
Meanwhile, the LHC is still operating at only half of its maximum energy, and the ALICE team expects to create even denser forms of quark-gluon plasma as the machine ramps up in the future.
为了达到维持热核燃烧所需的高密度压缩状态，激光驱动聚变对光束能量沉积的均匀性提出了很高的要求。
Laser driven fusion requires a high degree of uniformity in laser energy deposition in order to achieve the high density compression required for sustaining a thermonuclear burn.
