查询词典 adding

The invention discloses a 3, 5-2-0-(4-chlorobenzene chlorobenzene)-2-deoxidising- D-red-furanoside that contains alpha body and beta body. The method includes the following steps: dissolving chlorine indicant into tetrahydrofuran, quickly adding to alcoholic solutioin, whisking and reacting, after reacting, vacuuming and steaming solvent to gain mixture of alpha body and beta body, taking separation by column chromatography to gain separated alpha body and beta body.

本发明公开了一种3、5-二-O-(4-氯苯甲酰基)-2-脱氧-D-赤-呋喃糖苷，它具有式表示的α体和式表示的β体，制备方法采用在室温下，将氯糖苷溶于四氢呋喃中，然后快速加入到醇溶液中，搅拌下进行反应；反应结束，减压蒸掉溶剂，得到白色固体，将该固体用石油醚溶解，过滤除去不溶物，再次减压蒸去溶剂，得到白色α体和β体的混合物，用柱色谱法进行分离，得到单独的α体和β体。

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.

有鉴於此，本文针对粒子群演化法之流程参考相关文献并稍作改变，使得粒子群演算法在结果的收敛上更具优势，本文的主要改进的方法包括：应用均匀设计的概念使得初始的粒子可以更均匀地分布在空间上；利用突变增加粒子之间的差异性与多样性；利用适当控制的最大速度限制及惯性权重控制，达到区域搜寻与全域搜寻的效果；应用新的边界处理机制处理设计变数超过上、下限的问题；利用区域强化搜寻针对粒子附近地区，再作进一步的搜索以得到更佳之结果；将各种方法综合后配合粒子群演算法使用，可以得到不错的结果。
