Chapter 8: We discuss the acceleration of multigrid by Krylov subspace approaches, and recognize the reason for slow convergence of algebraic multigrid methods is that error reduction is significantly less efficient for some very specific error components which may cause a few eigenvalues of the algebraic multigrid iteration matrix to be considerably closer to 1 than all the rest. However, the eigenvectors belonging to the few isolated eigenvalues can be expected to be typically captured after only a few conjugate gradient iterations, which accelerate algebraic multigrid algorithms. Theoretical analysis and numerical results of some practical problems show the iterant recombination accelerates algebraic multigrid convergence.
第八章:先介绍用Krylov子空间迭代法加速一般多重网格方法收敛的基本框架,然后紧紧抓住引起代数多重网格方法收敛减慢的根本原因往往是误差减小对几个特别的误差分量不明显,这导致代数多重网格方法的迭代矩阵的几个特征值接近于1,而共轭梯度方法则能比较典型地捕捉属于孤立特征值的特征向量,从而推导出有效的共轭梯度加速算法和程序实现,不仅从一些具体的实际应用例子的数值结果去验证迭代复合加速收敛的效果,而且还从理论上分析了预处理共轭梯度法加速代数多重网格法收敛的机理。

By using the kernel function, the input space is mapped to a high dimension feature space where the data are expected to be more separable, the initial centroids in the feature space are selected by applying the KRA algorithm, and the large and small clusters are partitioned and the outliers can be split from the large clusters iteratively after the kk-means clustering. As a result, the audit data can be clustered better. Secondly, the closed sequential patterns mining algorithm CloSpan is improved according to the restrictions that is composed of the axis properties and reference properties.
该方法通过核函数把数据样本空间映射到一个高维的特征空间,使数据在新的空间中具有更好的可分离性;在特征空间采用KRA算法选取初始聚类中心,然后在核k-means聚类的基础上,划分出大簇小簇并在大簇中分离出异类再次进行核聚类,从而不断地优化聚类结果。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.
结果表明:培养120 h后诺卡氏菌达到最大生长量;诺卡氏菌在黄铁矿和闪锌矿表面发生明显的选择性吸附,在黄铁矿表面的最大吸附率可达到96.99%,而在闪锌矿表面的吸附率大都在20%以下;诺卡氏菌在两种矿物表面于20 min内即可达到吸附平衡; pH值是影响诺卡氏菌在两种矿物表面发生选择性吸附的关键因素, pH在4~10之间时,选择性吸附现象明显;矿浆浓度超过6 g/L时有利于发生选择性吸附;细胞悬浊液浓度、搅拌速度和温度对吸附效果影响不大,均可产生选择性吸附。

She married life long, so be called"the virgin queen"/"the virginity queen".was placed in inner part england because of religious partite confusion appearance when she ascend the throne, but she kept not only and successfully england of unify, and at through the near half for century of governance after, make to become europe england the most strong, be rich with of one of the nation.england the culture also comes to an a peak in this period, flowing out to appear such as the shakespeare, the bacon is such well-known person.england's colony in north america also starts establish in this period.her governance expects in the top of the british history to be called" lisa the white is period", also being called"golden age"..
她终身未嫁,因此被称为&处女女王&/&童贞女王&。她即位时英格兰处于内部因宗教分裂的混乱状态,但她不但成功地保持了英格兰的统一,而且在经过近半个世纪的统治后,使英格兰成为欧洲最强大,富有的国家之一。英格兰文化也在此期间达到了一个顶峰,涌现出了诸如莎士比亚,培根这样的着名人物。英国在北美的殖民地亦在此期间开始确立。她的统治期在英国历史上被称为&伊丽莎白时期&,亦称为&黄金时代&。。

Years of age do not eat honey, honey is a single sugar, the negative absorption, the same as glucose, do not eat, constipation can rule by other means, such as cooked apple to give him water to drink, or吃梨mud, pitaya can, my son is constipated the past two days, I cut half a dragon fruit for him to eat, because太凉, it can not be too much time to eat, so eat a quarter of a morning, afternoon, eat a quarter of of a stool as soon as they become soft, and give him water to drink, not to eat sweet baby food, because your baby's taste is very sensitive and may feel that the taste of the general adult non-sweet sweet baby food to said to be just, and not after the taste he will be getting heavier and heavier.
2岁以内都不要吃蜂蜜,蜂蜜是单糖,不利吸收,就像葡萄糖也是一样的,都不要吃,治便秘可以用别的方法,比如煮苹果水给他喝,或是吃梨泥,火龙果也可以,我儿子这两天也是便秘,我是切半个火龙果,给他吃,因为太凉了,也不能一次吃太多,所以早上吃四分之一个,下午再吃四分之一个,大便马上就变成软便了,多给他喝开水,不要给宝宝吃过甜的食物,因为宝宝的味觉是非常敏感的,一般大人尝过觉得似甜非甜的食物对宝宝来说是刚好的,不然以后他的口味会越来越重。

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.
