Instead of being three dimensional, space actually has more dimensions that are curled into little loops too small to be detected except in a high-energy particle collision.
空间不是三维的，事实上拥有弯曲成环的多个维度，这些环小到只有在高能粒子碰撞时才能检测得到。

When density of precipitated slurry is too high, because of the collision among particles, big spindly aggregates which are made of ultra-fines are born in reactor at the action of surface energy.
当体系中浆液密度较高时，颗粒由于相互间的碰撞在表面能的作用下团聚成纺锤形的大颗粒。

The higher sputtering yield would result from multiple collision, lateral sputtering and high density energy deposition of gas cluster ion beam.
