  1. 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
  2. A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide. a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc., is constructed by using boundary condition of mental waveguide, variational method and boundary element method. by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown. although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide

    把矩形波導一個寬面外突成均勻曲面構成的新波導統稱為共形波導.利用金屬波導邊界條件、變分法、邊界元素法構造這種新波導中主模場的一種近似解表達式，包括曲面橫截線為對稱、非對稱圓弧，拋物線弧，雙曲線弧，橢圓弧等.然後根據等效原理，推導非對稱圓弧矩形波導曲面上窄的縱向半波長縫隙的等效諧振電導的近似計算公式，給出計算曲線.這種解雖然是近似的，但卻能解決這類共形波導縫隙天線的工程設計
  3. For safety s sake, he took a routine check around his apartment and when he got to the kitchen, he heard a squeaky sound coming from the gas pipe leading to the stove. he checked it carefully and found that the pipe had a break
