這種方法的積分方程的積分核里含有復雜的微積分運算,為了簡化計算,本文在推廣的海倫積分方程的基礎上,對方程進行了簡化,推導了nakano方程,並以平面阿基米德螺旋天線,平面等角螺旋天線,軸向模圓柱螺旋天線,具有固定升角的圓錐螺旋天線和圓錐等角螺旋天線為例,用矩量法求解了天線上的電流分佈,研究了螺旋天線輻射的寬頻帶特性,所得的結果均與參考文獻吻合很好。The result indicates that, in the course of the rainstorm in huoshan, there are obvious low - level jet of great intensity, infection of mesoscale shear line, enhancement of plus vorticity which increases intensity of convergence, improves ascending velocity and brings on precipitation, and quick enhancement of helicity which provides the basis to forecast, in addition, convergence of moisture flux and analyzed potential vorticity which reflects baroclinic convective instability sufficiently indicate the characteristics of the rainstorm
結果表明:此次霍山暴雨發生前後,存在明顯的大強度低空急流,並受到中尺度切變線的影響,而且正渦度的加強引起了輻合加劇,提高了上升速度從而引起降水,同時暴雨發生前螺旋度的迅速增強,也為預報提供了根據,另外水汽通量的輻合以及分析位渦反映出的斜壓對流不穩定都充分體現了這次降水的特點。Compared to an ordinary rudder, the value of lift coefficient of ichthyoid rudder is about 30 % higher and the maximum rudder angle of it nearly reaches 45 degrees. ichthyoid rudder is a design under such a conception as to effectively utilize the propellers slipstream for rudder action, and featured by having a fish - shaped one - piece construction that is to say - no part of ichthyoid rudder can move in the water
其研究的魚形舵是一個沒有在水下移動的魚尾形剖面單片結構,增加了全舵的剖面拱度,使螺旋槳尾流的折射水量增強,進而增大了水動力的作用,使之比普通流線形舵的升力提高30左右。Fly straight and level form left to right as the helicopter is just about in front of the pilot, pull back cyclic, adjust the collective to maintain constant altitude and speed and hold the back cyclic as the helicopter completes one ( 1 ) full traveling tumbling back flip to upright
