种特征

These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.

这两方面也就是本文中第三章所讲的生成序列和扰动序列，这一章中我们主要研究了这两个因素对分数傅立叶变换算子的影响及它们之间的关系；当然还有另一种看问题的角度就是从算子的周期性和特征子空间的分布的角度，这就是第二章中所介绍的内容，在这里我们给出了两个三周期的分数傅立叶变换算子并比较了其特征性质。

On the basis of its importance both in theoretical research and practical application, gait recognition needs to be further studied. With the help of current research findings, this thesis has made the following innovative contributions: 1. Based on the perceptual shape descriptors and the eigenspace transformation, a new automatic gait recognition algorithm is proposed. The principal component analysis and the multiple discriminant analysis are used to reduce data dimensionality and to optimize the separability of different classes.

鉴于步态识别技术具有重要的理论研究意义和实际应用价值，本文对其进行了深入的研究，取得了以下研究成果： 1、利用主成分分析方法和多重判别分析方法进行特征降维，提出了一种基于感知轮廓描述子和特征空间变换的自动步态识别算法。

这两种初始心理品质的人群在幼儿时期表现的尤为显著（因为还较少受到后天家庭、社会对他们性格心理的塑造，从而他们的心理特征较多的体现了先天的初始心理品质特征）：比如有的小孩胆子小，怕见生人，而有的孩子则不畏生人。

Embryological observations on Crawfurdia delavayi, Tripterospermum cordatum, T. chinense, Gentiana striata and Pterygocalyx yolubilis show that the group under study is greatly diverse in differentiation and development of anther wall, type of ovule and placentae, synergid and antipodal cell in embryo sac, testa and embryogeny etc. The embryological characters are different among Crawfurdia, Tripterospermum and Gentiana Sect.

胚胎学 本文对披针叶蔓龙胆C.delavayi、双蝴蝶T.chinense、峨眉双蝴蝶T.cordatum、条纹龙胆G.striata和翼萼蔓P.voiubilis作了较详细的胚胎学研究，这些类群在花药壁的分化和形成、胚珠和胎座类型、卵器中的助细胞和反足细胞、种皮以及胚发育等特征上存在差异，并且在胚胎学特征上各自拥有原始和进化的性状。

In 2006, more than 10 provinces of China have experienced an epizootic outbreak of pig diseases characterized by high fever, reddened skin and high morbidity and mortality.

猪生殖与呼吸综合征（Porcine Reproductive and Respiratory Syndrome， PRRS）是一种以妊娠母猪的繁殖障碍和仔猪的呼吸道疾病为特征的病毒性传染病，该病的病原，PRRSV，已成为危害全球养猪业的主要病原。2006年，国内十几个省市内爆发了由以发热、皮肤发红、高致病率和高死亡率为主要特征的疑似猪生殖与呼吸综合征的传染病。

利用K-L变换提取字符图像的特征，并且结合一种使最小错误率上界最小的迭代方法使特征的选取更加准确。

The optimum models were obtained by non-linear fitting to describe the kinetic processes of adsorption of Cd on four types of soils in Northeast, China. According to the results, exponential equation and exponential function equation were more appropriate to fit the kinetic process than other equations.
