So, based on previous research achievement and the knowledge regarding molecular movement and calculus and numerical value analysis, practical calculating method is set up in this paper : 1
因此本文在已有研究成果的基礎上，利用分子運動論、微積分、數值分析等相關知識，建立了實用的鋼筋初始銹蝕時間的計算方法： 1 -
Thirdly, the surface height at the point can be gotten by applying composite numerical integration. according to variational calculus and finite difference method, the fitted surface is further iterated and modified, so the best reconstruction surface can be finally obtained
然後通過復化積分確定選取點的高度值，再利用變分和有限差分思想對所得擬合表面進行進一步的迭代和修正，從而減小誤差，獲得最佳再建表面。 -
A new system of nonlinear equations can be formed from the variation gray of same point in multiple images and the optimum solution of the system can be obtained, so that the normal vector at that point of the surface can be defined. then we can get the surface height at the point by applying composite numerical integration. according to variational calculus and finite difference method, the fitted surface is further iterated and modified, so the reconstruction error can be reduced
根據多幅圖像上固定位置一點灰度值的變化列多個非線性方程，通過求解該非線性方程組，確定出各選取點的法向量；然後通過復化積分確定選取點的高度值，並利用變分和有限差分思想對所得表面進行進一步的迭代和修正，以減小重構誤差。 -
