  1. The directrixes of the in former two transmissions are the loxodrome and the geodesic on the pitch cones, that of the latter is an equal - pitch line along the direction of straight generatrixes in the hyperboloid surface, also is the vertical trajectory of the straight generatrixes

    前兩種傳動形式的準線分別為節錐面上的斜航線與測地線，後者的準線為單葉雙曲面上沿直母線方向的等螺距曲線，且為直母線族的正交軌線。
  2. Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature. finally, we will employ the minkowski ' s support function to construct a new kind of non - circular smooth constant breadth curves in order to attack some open problems on the constant width curves ( for example, whether there is a non - circular polynomial curve of constant width, etc. ) in the second part, we will first follow the ideas of gage - hamilton [ 28 ], gage [ 26 ] and the author ' s dissertation [ 47 ] to present a perimeter - preserving closed convex curve flow in the plane, which is from physical phenomena

    其次，對雙曲平面上的曲線引入平均測地曲率的概念，並討論雙曲平面上凸曲線的嵌入性與它的平均測地曲率之間的關系，其目的是為了將雙曲平面上曲線的性質與歐氏平面中曲線的性質作一些對比；最後，我們利用minkowski支撐函數構造了一類新的非圓的光滑常寬曲線，其目的是想回答有關常寬曲線的一些未解決問題（如是否存在非圓的多項式常寬曲線
  3. Finally, this paper detailedly introduces the application of preloading method combining with vacuum stack - load in the practice of a freeway project. three sorts of experience calculation method of final settlement which based on the settlement data measured in - site are contrastively analysed, and points out the hyperbola method be recommended for settlement predicted because it accord with the actual instance of guangdong pearl river delta area, and bring up the range of settlement correcting coefficient corresponds to the characteristic of the region

    最後，本文結合某高速公路工程實踐，詳細介紹了真空聯合堆載法在高速公路上的應用，並利用實測沉降曲線對三種預估最終沉降量的經驗方法進行了對比分析，提出了雙曲線法計算最終沉降量較符合廣東珠三角地區，並提出較符合地區特點的沉降修正系數取值范圍，可供類似工程參考。
