    本論文主要包括以下內容：介紹了超環面行星蝸桿傳動的傳動原理及各構件間的運動關系，分蝸桿固定和定子固定兩種情況，給出了這種新型傳動的傳動比計算公式，得出了各輪齒數與計算圓處螺旋升角間的關系和各構件間的裝配關系，從而為該傳動的優化打下理論基礎。
  5. In terms of deriving the maximum trapped - wavelength and the critical emitting angle of elevation for electromagnetic wave which can forms duct propagation and introducing the four kinds necessary condition for electromagnetic wave to form duct propagation, under these conditions we now have the radio wave bent back towards the earth

    結果與實際觀測到的波導傳播時的回波結構相同，說明，根據不同的大氣層結，利用電磁波的波導傳播的射線追蹤方法可以基本上確定電磁波的傳播軌跡。
  6. Radar ( radio detection and ranging ) detect the objects in the space and estimate the objects " parameters, such as distance, azimuth, angle of elevation, velocity, by transmitting radio wave. in national economy, it is used in navigation, weather forecast, geological mapping, military affairs and so on

    雷達利用發射的無線電波探測空間中的物體並確定其距離、方位角、仰角、速度等各項參數，廣泛應用於導航、氣象預報、地質測繪、軍事等領域。
  7. Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum

    研究結果表明：傾斜角度一定，當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時，流體速度和熱質傳遞速度從高逐漸變低並出現最小值，此後隨著向下浮力的增大，流體向下流動且隨| b |的增大而加速，熱質傳遞速率隨| b |的增大而重新增大。
  8. This means that the dielectric property changes with height and allows a slight increase in the speed of a radio wave as we move upwards through the atmosphere. this in turn means that if a radio wave moves away from the earth at an angle less than 90 degrees, then the upper part of the wave travels faster than the lower part. therefore even under normal conditions this can in effect bend, or refract, the wave back down to earth

    其中一種顯著的現象是：在一定的氣象條件下，在大氣邊界層尤其是在近地層中傳播的電磁波，受大氣折射的影響，其傳播軌跡彎向地面，當曲率超過地球表面曲率時，電磁波會部分地被陷獲在一定厚度的大氣薄層內，就好像電磁波在金屬波導管中傳播一樣，稱為大氣波導傳播，形成波導傳播的大氣薄層稱為大氣波導層。
