By iteratively combining these two procedures we achieve a way of training the configuration of RBFNN. In addition, the algorithm is very robust with respect to the noise level. Simulation experiments show that the proposed algorithms are sound. In chapter 3, which is the extension of chapter 2, the improvements of the architectures of RBFNNs and the solutions of their relating problems are discussed, Firstly, an new distance metric is advanced and a forward orthogonal least square selection procedure is applied to learning the parameters of classification function and selecting the important input nodes.

首先分析了目前存在的同时确定RBFNN结构和参数的方法的缺陷，在此基础上提出了用基于拉马克的进化学说的进化编程算法来改进算法，以克服某些缺陷；然后针对受到严重噪声污染的系统，如何提高RBFNN的泛化能力的问题，利用基于AIC的适应度函数的改进遗传算法学习结构和参数；最后介绍基于MDL原理的方法，将优化网络的结构和参数分为两个阶段：训练和进化，先自适应地改变RBFNN基函数的中心和宽度，同时训练输出线性权值，再用基于MDL原理的适应度函数的标准GA来优化隐层节点，通过交替使用这两过程达到训练RBFNN的结构和参数的目的，该算法具有较强的鲁棒性。

Using the estimates of character sums over Galois rings and the trace de scription of primitive sequences over Zpe, we obtain an estimate for the frequency of the occurrences of any element in Zpe in one period of a primitive sequence, which is better than Kuzmin's results[1] if n ＞ 4e, where n is the degree of the generating polynomial of the primitive sequence.

范淑琴 ，韩文报文研究了Zpe上本原序列的元素分布。利用Ga，lois环上的指数和估计和本原序列的迹表示，得到了Zpe中各元素在本原序列的一个周期中出现频率的一个估计。当n＞4e时(n为本原序列生成多项式的次数)。我们的估计优于Kuzmin的结果[1]。

A new scheme of target discrimination in SAR images, consisted of frames, models and algorithms, is proposed. Under such a scheme, a global frame, combining orderly the algorithm based on feature extraction and that based on knowledge, is then proposed. Moreover, in the method of target discrimination based on feature extraction, a "loose-coupling" model is given. The existing features are chosen and three new features about the contrast are given under the "loose-coupling". Meanwhile, an algorithm of feature selection based on Genetic Algorithm is also modified to solve the problem that the existing algorithm can not evaluate the goodness-of-features comprehensively. The weighted quadratic distance discriminator is designed to improve the performance of target discrimination. Finally, a method based on the knowledge of target groups to remove clutter false alarms is also given.

Methods The inhibitory effects of Taurine (50 mmol·L-1) on glycolaldehyde (0.1 mmol·L-1) induced DNA damage in spleen lymphocytes of mice were studied in vitro using single cell gel electrophoresis,and 2,4-dinitrophenylhydrazine measurement was used to detect quantitatively the effects of Taurine on carbonyl compound contents in a reactive system.

Inaddition to that,LFY has a second role in the activation of the floral homeotic genes that specify the identity of organs in the flower and is a key intergrator of the outputs of floral inductive pathways.DFL, a FLORICAULA/LEAFY homologous gene,which cloned from C.lavandulifolium,was a key gene of florescence for C.lavandulifolium.

LEAFY基因在植物成花过程中意义重大，它不仅决定着花由营养生长向生殖生长的转变，它还接连GA成花途径和长日途径的信号继而诱导花分生组织的转变，同时还是活化花器官基因的关键基因。

In 2000, Nishida et al synthesized the PPDO whose molecular weight could reach 142,000 but the monomer conversion could only reach 79.4% by using stannous octoate as catalyst with co-initiator under conditions that T = 100oC, M/I = 4900, t = 20 h, in 2000, the enzymatic polymerization of PDO was carried out at 100oC for 15 hours using 5wt% immobilized lipase CA by Nishida et al.

这主要是因为PDO的结构相对稳定，开环聚合要比GA、LA、CL困难一些，而且用于PDO开环聚合的催化剂体系单一，主要集中在Ti， Zr， Sn， Ld， La， Yb， Hg等重金属，然而这些重金属作为副产物，不容易从PPDO中分离出来，阻碍了PPDO作为医用材料的应用，这也造成了PPDO的成本昂贵。
