孔数 meaning in English
hole number
no. of holes
Examples
- Hole density : the number of holes per unit area on a pcb
孔密度： pcb上单位面积上的孔数。 - The features in an electroformed stencil are formed in one process so aperture count does not affect costs so dramatically
电铸钢网的特性是一次形成的，因孔数对成本的影响不是那么大。 - Finally , laser cutting is a serial process , so time - to - manufacture increases as aperture count does , impacting the stencil ' s final cost
最后，激光切割是一系列过程，孔数增加，制作的时间增加，影响钢网最终成本。 - However in aspect of reducing channel height , via number and average route length , the results from the greedy channel router is not as good as the results routed by hand . more studies are required for better algorithm
但对贪婪算法来说，在减少通道高度、通孔数和平均布线长度方面都还比不上人工布线，更优良的通道布线算法有待于进一步的研究探索。 - The results show that : the whole bit wear process can be divided into three phases ; the regularity of the machining time per hole with the number of holes machined is close to a periodic variation ; higher machining efficiency or working life can be obtained when the drilling pressure and the wall thickness of the bit are advisable
发现钻头的整个磨损过程可分为3个阶段；孔加工时间随孔数近似呈周期性变化；钻压和钻头壁厚适当时，可获得更高的加工效率或者工具寿命。
