Abstract : a new waveguide which can change the wide wall of a rectangular waveguide into a symmetric arc wall is named as a cam - rectangular waveguide. comparing to sectoral waveguide, the new waveguide has the same voltage characteristics and is easier to be produced and fixed. an approximate formula of the dominant mode fields and the normalized conductance of a longitudinal resonant slot cut in the curved wall of a cam - rectangular waveguide are given. a resonant slot linear array in c & x band is designed, in which the slot voltage distribution is equiphase and the input is matched. the input voltage stationary ware ratio and the h - plane pattern of the antenna are measured. the experimental results show the conformance with theoretical results
文摘:把常用的矩形波導一個寬面改成圓弧形構成的波導稱為圓突-矩形波導.這種波導與扇面波導相比：電性能相當；波導管結構更加簡單，容易加工，便於安裝.文中給出圓突-矩形波導中主模場，圓曲面上縱向槽歸一化諧振電導近似公式.設計了c和x波段波導曲面縱向諧振縫隙線陣，縫隙電壓相位為同相分佈，輸入端匹配.實際測量了天線輸入端電壓駐波比和h面方向圖，理論與實驗相吻合Availing himself of a handle that projected from a half - fallen door, he tied the animal safely and having drawn a red cotton handkerchief, from his pocket, wiped away the perspiration that streamed from his brow, then, advancing to the door, struck thrice with the end of his iron - shod stick
他利用從一扇半倒的門上突出來的門閂，把馬安全地系了起來，愛撫地拍了拍它，然後從口袋裡抽出了一條紅色的棉紗手帕，抹了一下額頭上流下來的汗。他走到門前，用鐵頭手杖的一端敲了三下。In order to get a finite element formulation to analyze singular heat flux fields, the weak form of basic equations and boundary conditions describing the 2d heat conduction eigenproblems is derived for the sectorial domains in the vicinity of the interfacial crack tip
