An on-line blind source separation algorithm of non-stationary mixed signals is presented. The algorithm uses the multiple time-delayed decorrelation and natural gradient rule to obtain the stationary point of the cost function, only a small number of observed samples is needed to minimize the Frobenius norm of the correlation matrices, so the computing cost is low and continuous separation calculation could be realized by on-line operation.

利用一种基于多时延解相关准则的代价函数和自然梯度原则，分别推导出非平稳信号在瞬态线性混合及卷积混合情况下的在线盲分离算法，仅通过对有限个时延样本的相关矩阵进行Frobenius范数最小化运算得到分离矩阵，计算工作量小，无需对样本进行分块处理，可实现对信号的连续跟踪操作。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

Further prospective studies are needed to evaluate the pathogenetic sequence, natural history, and risk of malignancy of metaplastic esophageal nongoblet epithelium.

为评估非杯状细胞柱状上皮化生的发病机制、自然病程和恶变的风险，仍需更多前瞻性研究。

In chapter 2 and chapter 3,the nonoverlapping DDMand overlapping DDM based on natural boundary reduction for 2-D exteriorHelmholtz problem are studied respectively,the convergence and the conver-gence rate of these algorithm are discussed,some numerical results are given.

其次，分别研究二维Helmholtz方程外问题的基于自然边界归化的非重叠型和重叠型区域分解算法，分析了这些算法的收敛性和收敛速度，并给出了数值算例。

The research applied landscape ecology, integrating land using, ecology networks, and the concept of human needed environment model addressed by Odum to build natural and cultural criteria which are used to decide natural factorsand cultural factors. Subsequently, applying the criteria and planning procedures to category land into agricultural and non-agricultural areas. The agriculture areas include basic grain production areas, and leisure agriculture areas. The non- agriculture areas include agriculture of river corridor ecology restoration areas and remnant cultivates lands. Above all, remnant cultivated lands are separated into wilderness, parks or indefinite areas because of different context.

本研究运用之理念包括地景生态学、整合土地使用、生态网络及Odum提出四种人类需求环境模型；据以研拟自然及人文面原则，进行自然因子(NDVI值、坡度、高度、土壤等)及人文因子之准则建构；再依准则及划设流程规划出农业及非农业区域二类型，其中农业类型包括基础粮食生产区、休闲农业区，非农业区包括河廊农业生态复育区及剩余耕地，其中剩余耕地又依背景因子不同划设为荒野化、公园化或模糊区使用。

Dialectic contains much points against science: dialectic , with simple opinion, its one dividing into two of opposite and consolidation broke nature's ordered and organic character; combing two into one being simply patched at least goes against thing's selectivity; law of the unity of opposite wrongly treats contradiction as principle, and does not deeply explore the objective principle of contradiction trending to utility; contradiction generalization dissevers the thing's utility, which denies the relativity of existence, truth, non-contradiction of rule being in relative condition and unique correctness.

辩证法就存在着诸多反科学之处：辩证法观念简单，其对立统一之一分为二打破了自然的有序有机性，而合二为一又简单拼凑，至少违反了事物的选择性原则；对立统一规律化，错误的把矛盾这一事物的状态当成了规律，而没能深入探索矛盾由对立趋向统一的客观规律；矛盾普遍化，割裂了事物的统一性，否定了存在的相对性，也否定了真理、规律在相对条件内的非矛盾性，唯一正确性；辩证矛盾核心论，乱用核心，否定了事物由低级趋向高级发展的客观规律；认识论如矛盾论，使认识等矛盾，使一切关系变成矛盾等等。
