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 -
Cluxtalx analysis indicated that the v - h + - atpase b, h and c subunits from halophyte s. salsa had high amino acid sequence identity with subunits from mesembryanthemum crystallinum, which is an inducible cam species as its growth rate is maximal at moderate salt concentrations. sequence alignment results suggested that the evolutions of v - h + - atpase subunits b, h and c were involved in environmental adaptation and these subunits of v - h + - atpase might have an important role in responses of plants to salt stress
Clustalx分析表明鹽地堿蓬液泡膜h ~ + - atpaseb 、 h 、 c亞基氨基酸序列與來源於兼性cam植物冰葉日中花液泡膜h ~ + - atpase的相應亞基具有最高的序列一致性，表明植物液泡膜h ~ + - atpaseb 、 h 、 c亞基的進化可能與環境刺激有關並且可能參與了植物對鹽脅迫的響應。
