無限長柱體-
Formulas of inversion and cosine transform spectrum of gravity anomaly of sphere, infinite horizontal cylinder, infinite and finite stretched staircase were deduced
推導出球體、無限長水平圓柱體、無限和有限延伸垂直臺階的重力異常餘弦變換譜及反演表達式。 -
The cosine transform spectrum of sphere are about the same as that of infinite horizontal cylinder, and that of infinite stretched staircase are very sharp, but that of finite stretched staircase presents well - regulated leap
球體與無限長水平圓柱體的餘弦變換譜相似，無限延伸垂直臺階的變化很尖銳，有限臺階的表現為上、下有規律的跳躍。 -
Firstly, this paper describes the optimization problem of thermal stress of fabrication process and steady work process for the hollow cylinder and the infinite plate. then, thermal stress distribution is calculated making use of theoretical formulation and the results can be validated by finite element method. in optimization, the restriction condition is heat insulation performance and the objective function is danger coefficient
本文首先對平板結構和圓筒結構梯度塗層在制備過程和穩定工作狀態下的熱應力優化設計問題進行描述，然後分別用解析法求解兩種結構的梯度塗層在制備過程和穩定工作狀態下的熱應力分佈，並採用有限元方法驗證了熱應力分佈的結果，在優化設計時，以危險系數為目標函數，以塗層的隔熱性能為約束條件進行設計。 -
Infinite cylinder problem
無限圓柱問題 -
To verify our computer code, we compute the added mass of a cylinder in the infinite domain and the semi - infinite domain as well as the inner one of two concentric cylinders, respectively. computational results match the analytical solutions quite well and we obtain certain valuable conclusions about added mass in different situations
為驗證程序的正確性，本文分別對單圓柱體在無限域和半無限域中運動的附加質量及雙圓柱體同心放置時內圓柱運動的附加質量分別進行了計算，計算值與理論值吻合很好；本文通過計算船在不同尺寸的船廂中運動的附加質量得出，隨下列條件的改變： 1 -
Since the pure cylindrical vesicles without ends are unstable even non - existence, approximations of torus and cylinder with spherical ends are utilized. the result from the former approximation means the condition of infinite long cylinder, which gives us no useful information. by spherically topological approximation, we get a set of conditions, all of which specify the range of parameters
利用環拓撲結構近似，我們得到了無限長柱狀膜的方程，但此方程沒有給出任何有用的信息；利用球拓撲近似，無論直接變分還是間接變分，都給出了一組條件，規定了參數的一個取值范圍，所以，球拓撲近似比環拓撲近似更實用一些。
