extreme dimension
解釋
極限尺寸-
In the end of this thesis, basis on the structure dimension of a specifically submarine, some solutions for strengthening structure are discussed, such as increasing the thickness of shell, reducing the spacing of frames, increasing the bending inertial moments of frame and setting the intermediate stiffer, when the extreme diving depth becomes 450m or 600m. comparing these structure weights, the excellent solution is the lightest structure
本文最後以某核潛艇指揮艙的結構形式作為計算實例，對下潛深度分別增加到450米和600米的情況，選擇增加殼板厚度、縮小肋骨間距、增加肋骨尺寸以及加設中間支骨等加強方案，經分析確定其中結構重量最輕的方案為最佳設計方案。 -
The researches show that the probability method for calculating the cavity dimension of injection mold is more reasonable than the extreme calculation method which is widely adapted now
研究表明，概率法計算注塑模成型零件工作尺寸比廣為採用的極值計演算法更為合理。 -
Since that we could get the extreme value xe and the optimal catching efforts e. for the difficulties of giving specific expressions and computational steps for the multi - species system we took a two - dimension model as an example to interpret the steps so that the readers can get a intuitive and peculiar understanding of the process
由於多種群系統難以給出具體的計算步驟和表達式，本文還以二維系統情況為例給出了計算和討論的具體過程，使讀者對這個問題能有更直觀明確的了解 -
In the thesis a new count expression of mesh fractal dimension is introduced, on the basis of it the storage and operation counts of directs solution methods, assembly global stiffness iterative methods and ebe iterative methods have been analyzed and compared, a conclusion has been obtained that the storage and operation counts of direct solution methods is the most, the storage counts of the ebe iterative methods is the least. estimating compute scale for ebe iterative methods at shuguang 2000 parallel computer, it is make out that compute scale is large in the extreme if make the most of the memory of every processor. by analyzing the parallel compute performance of 2d upend - step flow calculation, it is proved that ebe iterative methods can achieve upper speedup rations
本文還提出了一種網格分維新的計算公式，並基於網格分維對直接解法，組集總剛矩陣的迭代解法和基於ebe的迭代解法等三種方法的存儲量和計算量進行了分析和比較，得出了直接解法無論存儲量和計算量均最大，基於ebe迭代解法存儲量最小的結論；在曙光2000并行機上估計了基於ebe迭代解法的計算規模，說明只要充分利用各處理機的內存，可解問題的規模是非常巨大的；對二維倒臺階流并行計算進行了性能分析，表明基於ebe策略的迭代解法能獲得較高的加速比。
