從國外進口的三坐標測量儀、德國萬能工具顯微鏡、智能平面度檢查儀、金相圖像分析系統、電動量儀、氣動量儀和日本的高性能動力轉向系統試驗設備,保證動力轉向器的性能質量。For the regular curves, we find two killing fields for the purpose of integrating the structural equations of the p - elastic curves and express the p - elastica by quadratures in a system of cylindrical coordinates. for the star - like affine curves, we solve the euler - lagrange equation by quadratures and reduced the higher order structure equation to a first order linear system by using killing field and the classification of linear lie algebra sl ( 2, r ), sl ( 3, r ) and sl ( 4, r ). we solve the centroaffine p - elastica completely by quadratures
對于正則曲線的情形,我們發現了兩個用於求解p -彈性曲線的結構方程的killing向量場並用積分將p -彈性曲線在一個柱面坐標系中表示出來,而對仿射星形曲線的情形,我們用積分方法解出了歐拉-拉格朗日方程,利用killing向量場及線性李代數s1 ( 2 , r ) 、 s1 ( 3 , r )和s1 ( 4 , r )的分類將高階結構方程降為一階線性方程,因此我們用積分完全解出了中心仿射p -彈性曲線。In a three - dimensional ocean model with curvilinear coordinates horizontally and a coordinate vertically, the adapted grids at a layer for interpolation in the eulerian - lagrangian method ( elm ) is unreasonable over steep topography, because the vertical distance between the adjacent grids in the same a layer is too large
摘要在水平曲線坐標和垂向坐標的三維海洋模式下,歐拉拉格朗日方法的插值如果在-面相鄰網格之間進行,那麼在水深變化劇烈處,由於-面相鄰網格之間的垂向距離較大,插值依據會顯得較不合理。This paper is composed of two parts including 5 chapters. in the first part ( including chapter 2 ^ 3 ), this paper explains an improved geometry - model method to eliminating eclipse shadow, using satellite imaging theory and projection theory to convert plane rectangular coordinates into rectangular spherical coordinates. otherwise, through studying eclipse ' s shape and size, this paper uses a math - function - model to eliminating eclipse shadow
本文共有五章,主要內容分為兩部分;第一部分包括第二、三章的內容,利用可見光雲圖成像原理以及點的投影法,將平面雲圖投影到三維直角坐標的球面上,對用於雲圖陰影訂正的原幾何模型法加以改進,得到改進的幾何模型法,並進行日食陰影訂正實驗;本文還利用數學函數模型法,通過研究月球在地球表面投射陰影的形狀及其受影響程度,從另一方面進行可見光雲圖日食陰影的訂正實驗研究。分享友人
