Our introduction of advanced computer control of machinery and equipment, and advanced laser perforation, EDM reaming, ultrasound, high-precision grinding and polishing line, and other processing machinery and equipment and strong technical staff strength.

本厂引进计算机自动控制的先进的机械设备，并拥有先进的激光穿孔、电火花扩孔、超声波、高精度研磨和线抛光等加工机械设备和雄厚的技术人员力量。

The voltag es used to open seals could also affect the stem cells, but Melosh explains they could solve this problem by recessing the por es so that the electric fields are more distant from the cells.

用于穿孔的电流有可能会影响干细胞，米洛许说，他们现在已经可以用把孔洞深埋的方式，将电场与细胞的之间的距离拉长。

Causes of perforation of alimentary tract:Defects of gastric musculature(5 cases),congenital malformations of small intestine(6 cases),malformations of colons and rectums(4 cases),necrotizing enterocolitis(7 cases)and meconium peritonitis(1 case).

消化道穿孔原因：胃壁先天性肌层缺损5例，各种先天性小肠畸形6例，结肠和直肠畸形4例，坏死性小肠结肠炎7例，胎粪性腹膜炎1例。

Played by the time it open, so piercing narrow, to be inserted into a cone rehousing the original ornaments.

饰的时候让它敞开着，以至于穿孔缩小，必须插入圆锥安置一个原来的首饰。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

Syringing may not be advisable for everyone, for example if you have a perforated eardrum or a history of ear infections.

syringing未必是可取的每一个人，例如，如果您有穿孔的鼓膜或历史的耳朵感染。

If you have a perforated eardrum, syringing can push little pieces of wax into the inner ear.

如果您有穿孔的鼓膜， syringing可以推动小件蜡进入内耳。

Automatic data processing by electronic means without the use of tabulating cards or punched tapes.

不使用穿孔纸带的自动的电子化数据处理。

The preproduction situation of commercial pure titanium (Gr.2) cross-rolled boring seamless tube was introduced, and the problems in it were analyzed. The effect of Q value on tube inner surface quality and boring problems were discussed.

中文摘要：介绍了工业纯钛（Gr.2）斜轧穿孔无缝管的生产试制情况，并对生产中遇到的问题进行分析，重点讨论斜轧管冷加工过程中Q值对管材内表面质量的影响及管材镗孔问题。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
