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4 press w et al. numerical recipes in c : the art of scientific computing. 2nd edition, cambridge : cambridge univ
然而值得注意的是，扇形在仿射空間中並不是一個曲線，它只是矢量空間中的一個矢量場。A device for converting energy form one form to another. in relation to computers, the term is applied to a read / write head, to detector of sector marks in a magnetic disc system, and to electronic / sonic pulse converters of delay line memory
把能量從一種形式轉換成另一種形式的裝置。在與計算機有關時，這個術語用在磁盤系統中的讀寫磁頭、扇面標記的檢測上，以及用在延遲線存儲器的電子或聲波脈沖變換器上。The movement of rotor is balanced ; while the quality of rotor distributes asymmetrically, the additive moving - pressure the equipment engineering company of chinese jialing group fetches in super - carb - prof ambi - whisking fan that is multi - stoves produce line runs under the circumstance of 950 or so. the leaves of fan are prone to distortion, which results in unbalanced vibration and affects the machine ' s normal movement severely
中國嘉陵集團設備工程公司從德國ipsen公司引進的超級滲碳氣氛（ super - carb - prof ）多用爐生產線的氣氛攪拌風機長期運行於950左右高溫環境中，其扇葉極易變形，從而造成不平衡振動，嚴重影響設備的正常運行。The concept of intersection set of " possible attacking sector " and its application in the fighter course determination for multi - target attacking are also discussed
同時還介紹了多目標攻擊「可能攻擊扇形區」交集的概念和在載機航線求解中的應用等問題。7 lee j - h, park h. morphological development and transformation of b ezier curves based on ribs and fans. in proc
從肋形和扇形的分解中我們可以從給定的n階bezier曲線定義n - 1個肋形。In figure 4 we see, for example, that in the fan of lines at the bottom of the figure, horizontal lines and lines at approximately 30 degrees to the vertical are resolved, while lines at other angles are not
比如在圖四中我們看到圖中底部扇形分佈的線中水平線和與豎直方向成30度的線可以分辨，其它的線則不行。分享友人
