English translation for "孔数"

hole number
no. of holes

Example Sentences:

	1.	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。
	2.	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。
	3.	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。
	4.	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。
	5.	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。
	6.	This paper presents an investigation on a new type of rubber damper , that is , a rubber damper with honeycomb structure . the honeycomb structure will enhance the energy dissipation of a rubber damper and as a result increase the damping of the damper . the performances of honeycomb dampers are experimentally tested by a test rig . the results show that the diameter and the density of holes of the honeycomb structure are important parameters in the design of the damper . for a damper of given size , there are optimum values of both parameters with which the damper provides highest damping . additionally the honeycomb structure does not change the correlation of damping to frequency . a practical honeycomb damper is designe d and applied to inlet pipe of a screw compressor in a petroleum factory for vibration reduction . the vibration of the pipe is obviously suppressed by the damper , at least 25 % 本文采用理论分析和实验相结合的方法，研究了蜂窝孔这种结构因素对橡胶阻尼材料阻尼性能的影响。在自行设计、制作的悬臂式阻尼测试实验装置上，对蜂窝式橡胶阻尼器的阻尼性能进行了大量的实验测试，初步找出了蜂窝孔孔径、孔数以及预压缩量等因素与阻尼器阻尼性能的关系。本文利用实验研究的结论，设计了一种专用的蜂窝式橡胶阻尼器，并应用于某厂螺杆压缩机进口管道的减振，取得了明显的减振效果。
	7.	Results show that all the geometric parameters have remarkable effects on combustion performance ; the swirl of intake air generated by skew intake holes enhances fuel - air mixing , minimizes dead zone and stabilizes the flame with reverse flow , but the excessive reverse flow can cause overheat in combustion chamber and exhaust ; the consistency of flow resistance in intake and exhaust system is conducive to the stability of heater performance 研究表明，燃烧室进气孔的孔径、孔数、孔的分布及方向等均对燃烧性能影响很大；斜孔所产生的旋转进气，虽具有强化燃气混合、消除死区和回流稳焰的作用，但回流过度会使燃烧室及排温过高；保证进排气系统流动阻力（压力）的一致性，有助于保证加热器性能稳定。
