  2. In the second part, firstly, the mathematical model for predicting hydrodynamic characteristics of varivec propeller under steady or unsteady condition are present, based on the general propeller lifting - surface theory, potential flow theory and green theorem. then, theoretical calculation methods for predicting hydrodynamic characteristics of varivec propeller designed above paragraphs are present, based on the finite basic solution method, the unsteady vortex lattice method and hess - smith method

    在理論計算部分，本文首先基於常規螺旋槳升力面理論、勢流理論和格林定理建立了定常和非定常狀態下全方向推進器水動力性能計算的數學模型，然後利用有限基本解法、非定常渦格法和赫斯?史密斯方法對全方向推進器定常和非定常狀態下的數學模型進行了數值離散，接下來針對前面所設計的全方位推進器進行了數值預報。
  3. The analysis of dry pv shows that the high pv dominate the area of typhoon, the higher is the center value of pv, the stronger is the typhoon. lt is also shown that the most important reason resulting in rainstorm is the cold air ( high pv ) which spreads to south from the upper troposphere or lower stratosphere and transports into the warm air. the joining situation of upper and lower pv area make vortex develop. pv transpotation reduces static stability, which increases the releasing of instability energy and makes rainstorm amplify

    對干位渦的分析表明：臺風或臺風環流區為高值位渦區，臺風越強，位渦中心值越大；對流層上部或平流層下部冷空氣（高位渦）的擴散南下與暖濕氣流的交匯是造成特大暴雨的重要原因，因為上游斜壓性的發展使對流層頂發生折疊，平流層與對流層相互作用增強，上下位渦區相接的形勢使低層渦旋發展，上升運動加強，位渦的下傳有效地降低了靜力穩定度，有利於位勢不穩定能量的釋放，使得暴雨增幅。
  4. It contributes to the development of the cyclone when the center of the potential vorticity is behind the cyclone at initial stages of the development of the cyclone and there is a manifest inverted conical subsidence zone under the 200hpa, which lies in the rear of cyclone

    氣旋的發展初期，位渦中心位於氣旋的後部， 200hpa以下有明顯的倒圓錐形下沉區，該下沉區位於氣旋的後部。這種形勢有利於氣旋上空的位渦增長。
  5. The advanced development on the new kinds of scroll profile has become the research focus in the profile design. used a new type scroll compressor of the combination profile in this paper, a scroll is constructed following this : the inner turn consists of the standard involute of circle, and the same to the outer turn. then the middle turn is one of arc

    本文所研究的新型組合曲線渦旋壓縮機最內圈以基圓漸開線構成，中間段以圓弧過渡，最外圈由圓漸開線構成，能發揮不同型線的優勢，是一種能滿足多性能較優要求、形狀性態良好的渦旋型線，與傳統的基圓漸開線構成的渦旋壓縮機相比，具有效率高、泄露量少、體積利用系數大等優點。
  6. In the metaphase of precipitation, the high - layer inertia - gravity wave presented indirect circulation posture circling the center of low - layer vortex. at this time precipitation became stronger and moved towards the east

    在降水的中期，高層的重力慣性波出現圍繞低層渦旋中心逆時針旋轉的形勢，此時降水開始加大並東移。
  7. The action that weak cold air penetrated into the tropical cyclone made the low pressure become vortex potential instability, and finally turned into kinetic energy. the results were that the center pressure of low became lower, the wind velocity around the cyclone was stronger and the precipitation became more

    冷空氣在中低層的滲透主要使大氣斜壓作用加強，使不穩定能量的積聚並最終釋放；還造成臺風渦旋位勢不穩定，使熱帶氣旋中心氣壓降低，周圍風力加大，因而產生更大的降水。
