secondary flat
解釋
次平面-
The primary of linear induction motor which drives the metro is installed on the chassis bogie, and because it is quite strict with laying down railway rail to use flat linear induction motor to drive metro, its secondary - - - - reaction board ( called induction board ), which is a kind of compound board of aluminum and steel, is fixed on the rail sleeper between the track. it is the airgap which is a gap between the primary and secondary of lim. the electromagnetic airgap is a very important parameter of lim
利用有限元法對直線感應電動機二維非線性渦流場進行了數值計算，並在此基礎上，運用電磁場有限元分析的專用軟體ansoftmaxwell2d對單邊型直線感應電動機的瞬態特性進行了模擬分析，得到電機運行過程中的電磁推力、法向力、初級電流、氣隙磁密等曲線，通過改變直線電機參數，分析了電機氣隙對其瞬態性能的影響。 -
Our sapphire wafer products can be manufactured according to customer specifications. wafer thickness, diameter up to 6 inches, crystal orientation, surface finishing and secondary flat can be customized upon request to suit a variety of commercial applications
我們可以因應客戶特殊需求，提供不同的厚度、晶面方向、拋光要求及次平邊等客制規格產品，甚至直徑達6英寸的精準平行度晶圓，以滿足多種產業應用的需求。 -
Secondary flat - a flat that is smaller than the primary orientation flat. the position of this flat determines what type the wafer is, and also the orientation of the wafer
第二定位邊-比主定位邊小的定位邊，它的位置決定了晶圓片的類型和晶向。 -
Assemble design is very important as a part of bridge crane design. as a visual reality technology applied in design and manufactual field, visual assemble technology has been gained quiet great development. some visual assemble system has been applied in industry. the research in this paper is combining vr and cad technology, to develop a special design system for bridge crane. in the study, we choose a advanced 3 - d cad software - solidworks to modeling the crane, and use an object oriented computer language - visual basic for secondary development of solidworks by its api function and ole interface. in this paper, it will introduce the crane ’ s automatic assembly and collision detection function of design system. the system program is written in visual basic and hanged to solidworks flat roof. so, it seems solidworks runs its own function when we run the program
本文的研究工作將虛擬現實技術與三維cad技術相結合，研究橋式起重機的虛擬自動裝配及裝配中的干涉檢查。在此研究中，作者選用先進的三維cad軟體平臺- solidworks ，進行起重機的建模;並運用面向對象的設計語言- visualbasic ，利用solidworks的api函數和ole介面對其進行二次開發，開發出起重機小車的創新虛擬裝配設計和干涉檢查系統。此設計系統是通過vb編程，在solidworks軟體平臺上外掛系統程序，程序的運行就如同solidworks調用自身功能一樣，來實現設計功能。
