secondary hole 中文意思是什麼
secondary hole
解釋
延燃孔-
When primary electrons hit the surface of the chunnel, secondary electrons are generated, which make the electron distribution at the exit hole of the chunnel more uniform
當初始電子碰撞絕緣壁時，會產生二次電子，而二次電子能改善電子在通道出口處的電子能量分佈的均勻性。 -
The current transformer is busbar type. the secondary windings and iron core are insulated by epoxy resin. the middle hole is used for busbar going through and mounting
本型電流互感器為母線式。二次繞組及鐵芯均澆注在聚脂樹脂內，中間窗孔供一次母線穿過及安裝用。 -
The current transformer is busbar type. the secondary windings and iron core are enclosed in a plastic crust. the middle hole is used for busbar going through and mounting
本型電流互感器為母線式。二次繞組及鐵芯均封裝在阻燃塑料殼內，中間窗孔供一次母線穿過及安裝用。 -
The zero sequence current transformer is full enclosed type. the secondary windings and iron core are insulated by epoxy resin. the middle hole is used for cable going through
本型零序電流互感器為全封閉式。二次繞組及鐵芯均澆注在聚脂樹脂內。中間窗孔供三相電纜穿過。 -
Sixth, a technology validation prototype system of the digital product assembly and key matching elements is developed. seventh, the secondary development of solidedge is put up and the assembly process and key matching elements. of the typical hole shaft assembly are researched. so the technology principle and implement method are validated
最後，開發了一種數字化產品裝配及關鍵要素匹配的技術驗證原型系統，在該系統中，通過對solidedge進行二次開發，以典型裝配副孔軸裝配為主要應用對象，分析了裝配過程及關鍵匹配要素，對所研究的技術原理及實現方法進行了驗證。 -
Measured hole mass flows and a constant static pressure mixing analysis, together with the measured losses, allowed the decomposition of the losses into three distinct entropy generation mechanisms : loss generation within the hole, loss generation due to the mixing of the coolant with the mainstream, and change in secondary loss generation in the " blade passage
論文還進行了葉片冷卻孔質量流的測量與常靜壓氣流混合分析，結合前述氣動力損失和冷卻空氣損耗的測量結果表明，端壁氣膜冷卻的綜合損失明顯地由三個部分組成：葉片冷卻孔內產生的損失；由於冷卻空氣與主流熱空氣的混合產生的損失；二次流的變化產生的損失。
