本論文在國內外關于球頭立銑刀設計、建模、加工等方面研究的基礎上，根據現有的mk6335a五軸數控鉆尖磨床刃磨運動的特點，應用微分幾何、包絡與反包絡理論、坐標轉換、數值分析等理論知識，研究了基於五軸數控磨床加工球頭立銑刀的數學模型及分析與模擬。 -
On the base of analysis of hydrologic geology from aquifer distribution, boundary conditions and dynamic characters etc. in the research area, the paper sums up the hydrologic geologic condition, builds up the conceptual model of groundwater resource evaluation and presents 2d calculation model, as well as numeric solution and computing flow chart. after introducing general solutions of mathematic models and implementation method of rectangular grid, the paper realizes the automatic technique of spatial dispersion rectangular grid of evaluation models based on gis. finally, the paper fulfills the integration of gis with groundwater resource evaluation models from gis - based basic management information, spatio - temporal dispersion of models, definition of subprogram and visual evaluation of parameters, as well as models simulation etc., and visualizes the results of evaluation models
論文以地下水超采?地下水降落漏斗?地面沉降現象較為嚴重的常州、武進地區作為研究評價區域，在對評價區域的含水層分佈、邊界條件和動態特徵等水文地質條件分析的基礎上，概化了其水文地質條件，構建了相應的地下水資源評價概念模型與數學模型，並給出其數值解法和相應的計算流程；論文在介紹數學模型的兩種常用數值解法和模型空間離散的矩形網格生成技術的基礎上，實現了基於gis的評價模型空間離散矩形網格的自動生成；最後，論文從基於gis的評價模型基本信息管理、模型空間時間離散方法、子程序包與模型計算參數可視化賦值、模型的擬合等方面實現了gis與評價區域的地下水資源評價模型的集成，並將模型評價結果可視化。 -
3. base on the numeric method of finite element, the influence of interrelated shift coefficient and tooth number z to bend intensity of gear is studied. with the increase of the tooth number, tooth root maximum pull stress decrease ; with the increase of the interrelated shift coefficient, tooth root maximum pull stress increase
3 、基於有限元數值計算方法，分析了不同關聯變位系數和齒數z對齒輪彎曲強度的影響：隨著齒數的增大，齒輪最大拉應力減小；關聯變位系數越大，齒輪最大拉應力越大。 -
