弧面成形板 的英文怎麼說
中文拼音 [húmiànchéngxíngbǎn]
弧面成形板
英文
forming shoe-
A two - dimensional plain strain finite element model of infinite plate is developed to investigate the ultrasonic wave propagation and scattering on three kinds of cracks : parallel to the surface, 450 oblique angle to the surface, and quarter - circle
摘要建立了無限長板的具有吸收邊界的二維平面應變有限元模型，在研究了脈沖超聲波在無限長板中傳播的基礎上，對板中平行於表面的裂紋、與表面成45的斜裂紋和四分之一圓周弧形裂紋三種情況的脈沖超聲波散射進行了重點研究。The angle spectrum of inputting optical signals is received by the input surface of arrayed waveguides. whereas the diffraction process of light beam outputed in slab waveguide is a process of " composing frequency and generating image ". the reason that fraunhofer diffractive pattern can be gained on outputting waveguide surface is that output ends of arrayed waveguide distribute on the arch structure which leads bent phase factor to offset the quadratic phase factor in fresnel diffraction
輸入平板波導內光束的衍射過程是「分頻成譜」的過程，在陣列波導的輸入面接收到的是輸入光信息的角譜；而輸出平板波導內光束的衍射過程則是「合頻成像」的過程，正是由於陣列波導輸出口排列分佈在圓弧形結構上，其彎曲位相因子消去了菲涅耳衍射中的二次位相因子，從而在輸出波導面上能夠得到夫瑯和費衍射圖樣。There was a carpet : a good one, but the pattern was obliterated by dust ; a fireplace hung with cut paper, dropping to pieces ; a handsome oak bedstead with ample crimson curtains of rather expensive material and modern make ; but they had evidently experienced rough usage : the valances hung in festoons, wrenched from their rings, and the iron rod supporting them was bent in an arc on one side, causing the drapery to trail upon the floor
一個壁爐上面糊著花紙，已經掉得一塊塊的。一張漂亮的橡木床，掛著很大的猩紅色帷帳。用的材料是貴重的，式樣也是時新的，但是顯然被人粗心大意地使用過：原先掛成一隻只花球的帳簾，給扭得脫出了帳鉤，掛帳子的鐵桿有一邊彎成弧形，使帷帳拖在地板上了。
