scanning hole 中文意思是什麼
scanning hole
解釋
掃描孔-
( 3 ) there are many flaws in direct laser metal sintering, such as the high remnants stress, micro - hole and micro - crack in sintering parts. in order to solving those problems, the programming of scanning paths is put forward, and several parts are prepared with different scanning paths respectively. the following conclusion is educed : the parts produced with short - side scanning path and same scanning direction have the minimum structure, the rigidity of parts prepared by short - side and same direction scanning path is highest, and the density of parts produced with the vertical scanning path is maximal
（ 3 ）針對採用大功率激光直接燒結鎳基高溫合金成形金屬零件存在的問題，如較大的殘余應力，製件中存在著微裂紋、微孔洞等缺陷，初步提出掃描路徑的規劃，並採用幾種不同的掃描方式進行燒結試驗，發現採用短邊掃描路徑和同向掃描能夠獲得更加細小和分佈均勻的組織結構，採用短邊同向路徑制備的試樣其顯微硬度最高，而採用變向掃描（垂直）路徑制備的試樣緻密性最好。 -
Via ports scanning, it can gained many useful information, also find out system security hole
通過埠掃描，可以得到許多有用的信息，從而發現系統的安全漏洞。 -
Targets made of ship - building steel, which is concerned, were penetrated by conical and flat - ended projectiles. the damage and failure behaviors of targets have been studied systematically by micro - hardness, metallography and scanning electron micrography. the results show that the ductile hole failures and back - surface petal failures are achieved when targets penetrated by the conical projectiles
本文以某船用鋼為研究對象，運用彈板侵徹試驗及顯微硬度、金相顯微鏡和sem等分析測試手段，研究了靶材在侵徹過程的物理變化和損傷規律，從而對尖頭彈和鈍頭彈侵徹船體鋼的物理過程有了較全面的了解。
