The author uses I-fuzzy quasi-coincident neighborhood system to introduce the concepts of I-fuzzy first countability and I-fuzzy second countability, and proves the degree to second countability in each of I-fuzzy topological space must be less than that to first countability, and gives the equivalent characterations about the continuity of function by convergence of sequences in first countable I-fuzzy topological spaces.

Aelthough the CPU time of each cycle in FBMC is 1.6 times that in MMC, FB schem is still an effective method for convergence acceleration.

本文进一步支持了以分子的平移扩散作为判别抽样效率的判据，指出接受几率在0.33——0.36之间的步长可能是合适的。

In order to balance global and local search ability,fasten convergence speed,avoid premature,the cross rate is automatically updated according to the generation.

该算法在运行中根据迭代次数自动地调整交叉概率因子，从而在搜索的初始阶段提高种群多样性，而在搜索后期加强局部搜索能力。

Moreover, the crosser were improved, and the optimization reserved strategy was used to accelerate the convergence without leading to premature.

对交叉算子进行改进，实施最优保留策略，加快了算法的收敛，并避免了早熟。

This paper proposes to use fuzzy logic controller to speed up the convergence of the crossover and mutation process.

本文的目的在于引进模糊逻辑控制器来加快交叉与突变过程的收敛速度。

The size of the equivalent stiffness matrix of the outer-domain is only related to the number of the crunode in the interface between inner-and outer-domain,so the final stiffness matrix has a very small size.The numerical results agree well with the analytical solutions and the present method is simple,quick and has a good convergence.

无限相似单元法是无限剖分与有限元方法的结合，它打破了有限元法的限制，把计算域剖分成无限个"有限"大的单元，同时采用一些数学方法，解决了求解无穷多个单元的问题[3—11]。

However, the smoothness and convergence of these methods are not satisfactory. Because cubic spline function can be a piecewise, and its second order derivative is continuous, it is smooth and convergent.
