  • coordinates : 坐標系
  1. Secondly, two carbon fiber reinforced composite beams were fabricated, and their modal frequencies were measured by an experiment method. thirdly, delaminations were modeled by pairs of nodes with the same coordinates but different node numbers, while the modal frequencies of these beams with different delamination location and size were computed by an eas piezoelectric solid element. moreover, a novel method combining computational mechanics and neural network was demonstrated for composite health monitoring ; the first five flexure modal frequencies obtained by fem were modified by a primary revising approach and were used to train the neural network

    本文較全面地評述了神經網路的應用模型、改進演算法等，編制了bp神經網路程序：制備了纖維增強復合材料試件，並進行實驗模態分析；利用坐標相同、節點號不同的方法模擬脫層損傷，基於eas列式的壓電固體單元計算了不同脫層損傷情況下的頻率信息；針對基於實驗數據訓練神經網路存在樣本不足的缺陷，本文提出了利用有限元方法對含有脫層損傷的復合材料試件進行數值模擬，以前五階彎曲模態頻率構建訓練樣本的新思路，並提出了一種初步的計算值修正方法，以此構建神經網路的訓練樣本：將實驗模態分析的結果送入訓練好的神經網路進行預測，實現了對復合材料梁的脫層損傷的定位和損傷程度的評估。
  2. Because some mouse location information is in client coordinates and some is in screen coordinates, you may need to convert a point from one coordinate system to the other. you can do this easily by using the

    由於某些鼠標位置信息使用的是工作區坐標，而某些使用的是屏幕坐標，因此，您可能需要將某個點從一種坐標系轉換為另一種坐標系。
  3. In this paper, the location and machining of huge workpiece is discussed, some characteristic point coordinates can be obtained by using nc machine tool and measuring equipment, then position of huge wokpiece under machine reference frame can be acquired by computing measure point and according cad model point

    摘要針對超大型工件的加工定位問題進行了探討，提出了利用數控機床本身結合一定的輔助測量設備對加工工件進行測量的方法，然後利用測量點與理論模型體的對應點進行數據計算，從而快速確定工件位置。
