  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

  4. By using ncep / ncar reanalysis data of height and wind, the inter - monthly lpac map, the climate lapc map, inter - annual anomaly map and mean variance map of monthly wind field of 850 and 500hpa and monthly height field of 850, 500, 150, 30hpa are calculated in a globe - belt area, which situates between 30 s and 75 n, from december 1957 to december 1997, according them we analysis the rule of the season transfer and anomaly of nh mean circulation. the results show that the climate map of lapc can describe the seasonal transfer process of large scale circulation better. the advance process of summer circulation establish is form south to north at the middle and lower level of the troposphere, that is reflected primly in the inter - monthly wind and pressure map of lapc ; at lower lever of stratosphere, the establish process is simulate to that of troposphere, and reflect of process of that the south asia high toward plateau ; at middle stratosphere the summer circulation establish begins at middle and high latitude initially, and then transmits to low latitude gradually, while the seasonal variability in mid - stratosphere is stronger than it in troposphere and low - stratosphere

  5. By calculating the feynman diagram in rtf, we find that when taking into account both the thermal photon emission, absorption and the virtual photon exchange processes, the infrared divergences at zero and finite temperature can be cancelled at the same time. the full quantum calculation results for soft photon radiation coincide completely with the poisson distribution obtained in the semiclassical approximation ( the coupling of the classical current and quantized field )
