1. How much blackness surrounds a singularity – in effect, the size of the black hole – is defined by the strength of its gravitational pull. 事实上，奇点周围有多大一块黑暗区域，也就是黑洞的尺寸，是由它所产生的引力大小来衡量的。
2. We pointed out the main distinctions between strong singularity problems in topology optimization and those which only have weak singularities. 详细论述了此类拓扑优化问题与仅具有弱奇异性的拓扑优化问题之间的本质区别。
3. The results show that this parallel manipulator has a large workspace, and no singularity in the useful workspace, so it is an ideal parallel manipulator for laser cutting. 研究表明该机床具有较大的工作空间且在有效的工作空间内不产生奇异，是一种理想的应用于激光切割的并联机床。
