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Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice
空氣間隙的存在使覆冰絕緣子表面的電場分佈發生了明顯畸變,間隙上承受了非常高的電壓,這使得冰凌尖端的電場變得相當強,一旦電場達到了電暈的起始電場,局部放電就在這一區域發生,進而產生局部電弧並逐漸發展成整串的閃絡,泄漏電流迅速增大,同時伴隨著冰的融化。Series of high pressure thermocouples thermalresistances and thermowells, the thermocouple take the form of spring - loaded, of which protective tube and flange are forged of special alloy, as well the thermowell are formed with bar stock drilled. more further, theconnecting between thermowell and flange can be compressed with tapered thread and the groove at the lower end of flange can be welded with argon arc. these thermocouples are usually used in high equipments of hydrogen cracking device, cracker and vaporizer etc for pressure - resistant in over 30 mpa, operating temperature from 0 up to 800
