1·As the gas expands rapidly in the surrounding area, it creates a temporary vacuum in the middle which determines a high-pressure implosion.
当气体在周围迅速扩张的时候，中间区域就会出现暂时的真空，而这造成了高压力的内爆。
2·The report also provides a scathing picture of just how weak Lehman's risk-management practices ultimately became - and how they contributed to Lehman's implosion.
该报告还列举事实，尖锐地说明雷曼的风险管理做法最终变得多么薄弱，以及这些做法怎样加快了雷曼的内爆。
3·Computational simulations are the main method to study fluid instability during an implosion in inertial confinement fusion.
数值模拟是惯性约束聚变内爆中流体不稳定性研究的主要方法。
