In this thesis, the system model of DS-SS system and the adaptive filter structure are first introduced . Then, the interference suppression(interferences including strong tone and NBI)using the LMS algorithm with adjudging and feedback is analyzed in detail.

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。

Development of the general selective attention parallels with the development of verbal mental age in DS children, while visual perception and shape discrimination are underdeveloping the verbal mental age. No difference is found in switching attention except error response of shape. DS children have worse performance in terms of sustained attention. Compare to verbal mental age, there is an uneven pattern of the development of attention.

2与词汇理解能力的发展水平相比，DS组儿童的一般选择性注意相对较好，但其视觉感知、形状辨别能力低于其词汇理解能力的发展；转移性注意和持续性注意也相对落后；注意力各组分与词汇理解能力发展不一致，处于不均衡状态。

By synthetically analyzing the variation characteristics of pre-earthquake anomaly before five moderate-strong earthquakes in East China since 1990,discussing the pre-earthquake anomalous shape of b value and so on we obtained the comprehensive criteria for medium and short-term earthquake anomaly before moderately strong earthquake in East China:high YH value anomaly—low b value anomaly—low C and YH value anomaly—low Ds and Dt and Σ value anomaly and high b value anomaly—earthquake.
