摘　　要：针对“二维时序效益大于三维时序”疑惑,提出将缘线匹配技术应用于最大化三维时序效益的一般方法。在此基础上,根据先前时序研究积累的经验认识,进一步给出并着重讨论了最大化三维时序效益的简化方法。以A achen 1.5级亚声轴流涡轮为例展示了该方法的实际过程和效果。结果表明,缘线匹配指导下,可以用较小的计算资源使最大化三维时序效益规程化,并且改进效果可观。Considering ＂why the benefit of two-dimensional （2D） clocking is always larger than that of the three-dimensional （3D） clocking＂ ,a general way of maximizing 3D clocking benefit by edge matching was put forward. On the basis of experience and knowledge accumulated from investigations on clocking, a further simplified method was presented and emphasized. Aachen 1.5 stage low speed subsonic axial turbine was used as an example of maximizing 3D clocking benefits by applying edge matching. The result shows that 3D clocking benefit can be maximized by routinely using edge matching with only little computation resource requirements, and the benefit is good enough to be paid more attention.
