  1. In chapter one, we propose a new mixed method called characteristics mixed finite element method for a convection - dominated diffusion problems with small parameter e : we handle the convection part whth backward difference scheme along the characteristics, obtain much smaller time - trunction errors and avoid numerical dispersion on the front of the peak curve of the flow : we use a lowest order mixed finite element method to deal with the diffusion part, so this scheme can approximate the unknow function and its following vector with high accuracy at the same time

    第一章中我們對小參數對流占優擴散問題提出了新的數值方法? ?特徵混合有限元方法,即對方程的對流部分採用沿特徵的後退分格式求解,以保證較小的截斷限並避免了在流動的鋒前沿數值彌散現象的出現;對流動的擴散部分採用最低次混合元方法求解,以保證格式對未知函數及伴隨量的同時高精度逼近。由於該方法中檢驗函數可取分片常數,此格式在某種意義上具有局部守性質。
