  1. 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,包括曲面橫截為對稱、對稱圓弧,拋物弧,雙曲弧,橢圓弧等.然後根據等效原理,推導對稱圓弧矩形波導曲面上窄的縱向半波長縫隙的等效電導的近似計算公式,給出計算曲.這種解雖然是近似的,但卻能解決這類共形波導縫隙的工程設計
  2. But, the measured - data is a very great quantity and every data contain all data of 1 - 25 harmonic, measured time can have hours to days. the count by hand is very heavy and over - elaborate, sometimes the statistics results is error. it won " t reach the analysis purpose and don " t obtain the curve of harmonic oscillation characteristic in a row frequency range

    可是,測試數據經常是大量的,每一組數據又包含從基波到25次波的所有數據,測試時間可能是幾個小時,有的甚至是幾時間,這樣的工作量由人工完成是常繁重的,又是常繁瑣的,有時還統計不出正確的數值,起不到應有的測試分析目的,更無法獲得連續頻域內的特性曲
  3. The ferroelectric materials for their excellent dielectric, piezoelectric, ferroelectric, pyroelectric, electro - opticial, phonon - optic and nonlinear polarization properties have been widely applied in many fields especially in microwave tunable devices, such as phase shifter in phased array antenna, resonantor and filter etc. as far as microwave tunable dielectric materials, barium strontium titanate ( bst ) and its doped series have been investigated intensively, which have about 50 % tunability
