Some of them are of advanced ones , such as 5 - face grinding machine , electronic beam perforator , vacuum brazing equipment , curvic coupling grinding machine , controlled atmospheric quenching over , 4 - axis and 5 - axis nc milling machines , equipment for multi - component impregnation , heavy - duty grinder and high speed broacher , etc 擁有先進的五面磨床電子束打孔真空釬焊圓弧端磨可控氣氛淬火爐和四軸五軸數控銑床以及多元共滲強力磨削快速拉削等一批先進加工設備。

For many years mr . song has taken part in planning , design and technical management of local telephone lines , fiber transmission systems and the beijing telecommunications network . he successfully developed a protective sub - tube of fiber - optic cable and a perforator for plastic tubes in telecommunications ducts , which are used widely across the country 長期從事市話線路、光纖傳輸系統和北京電信網的規劃、設計和技術管理工作,先后研制成功了光纜保護子管和電信管道塑料管穿孔器,并在全國得到普遍推廣。

It provides performance advantages over the conventional perforator with the same diameter and similar charges , its penetration depth is increased by 7 % and entrance hole volume by 10 % 由于采用了復式射孔槍和復式射孔彈結構,使射孔彈和火藥能量得到充分利用,與一般的槍徑及彈型的射孔器比較,其穿孔深度提高7 %以上,孔容提高10 %以上。

According to ground experiments , the performance of hybrid enhanced perforator such as gun size after firing , charge arrangement and penetration is much better than other conventional perforators 經地面槍體脹徑實驗、固彈方式、穿深對比實驗證實,雙復射孔器槍體脹徑符合標準,固彈方式牢靠,其性能明顯優于其他類型的射孔器。

The powerful perforator flap concept allows transfer of tissue from numerous , well - described donor sites to almost any distant site with suitable recipient vessels 強大的穿支皮瓣概念允許許多已被描述很好的供區組織通過合適的受體血管轉移到幾乎任何遠的位置。
