To reduce the computation complexity of the eigenspace-based adaptive beamforming algorithm and improve the performance of it with a small number of snapshots,a modified eigenspace-based adaptive beamforming algorithm based on an unitary transformation is proposed.

1引言在众多阵列信号处理算法中，Feldm an等提出的基于特征空间的自适应波束形成算法[1]由于具有较强的稳健性能而受到学者们的广泛重视[2-4]，但ESB算法需进行复矩阵求逆和特征分解，计算复杂度高。

It was proposed in the 1960's and developed rapidly in the 1990's. However, some theory problems, for example, the fluid dynamics and mass transfer during the filling up period which could not be dealt with in conventional distillation theories has been remained unstudied. And the simulation and mathematical models have to be made based on some assumptions, which are different from the actual situation obviously. Therefore the further development of DACO was restrained in the past years.

该操作方法自20世纪60年代提出，90年代以来得到了迅速发展，但众多学者的研究基本上集中在优化操作及其与传统恒回流法的比较，而许多重要的基本理论问题至今缺乏研究，特别是传统精馏理论无法涉及的塔内无回流充液阶段的流体力学和传质问题一直没有得到很好解决，导致了动态累积循环操作法的数学模型和模拟计算只能以与塔内真实状况相差很大的简化假设为基础，这严重地阻碍着动态累积循环操作法的进一步发展。

Statute laws of a state and customary laws of minority nationalities differ in their features and we can conclude their con flicts by examining marital phenomenon of the minority nationalities in the western villages as following:1.conflict between u-ni versal and special justice;2.conflict between the modern legal culture and traditional one;3.the conflict between"transplant -ed"law and the features of the local nationality;4.the conflict between the state's will and regional pow er.

从广义上看，"习惯法是人们公认并被视为具有法律约束力的一些习惯、惯例和通行的做法"。为了和国家制定法本质上的"国家意志、统治阶级意志"相对照，有的学者则更强调习惯法作为一种知识传统，是"生自民间，出于习惯，乃由乡民长期生活、劳作、交往和利益冲突中显现，因而具有自发性和丰富的地方色彩。"

During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。

Background: Having been long seen as a psychosomatic disease, hyperemesis gravidarum has, received little attention in Taiwan psychiatry. The Case: We are presenting a case of 35-year-old married woman with HG in her 11th week of gestation.

背景：自十九世纪末期起，就有学者将妊娠剧吐视为心身疾病的一种，然而这种看法在台湾精神医学界似乎并不广为人知。

From M-M theorem which was put forward by Modigliani and Miller(1958), basing on the neo-classical paradigm, many western scholars began to relax the Neo-classical assumption of M-M theorem gradually, and modify the application scope of"irrelevancy"proposition, in realistic condition, to enrich and develop modern corporate finance theory continually.

自Modigliani和Miller(1958)在新古典范式下提出著名的MM定理以来，西方学者逐步放宽MM定理的新古典假设，修正&无关性&命题的适用范围，在现实条件下不断丰富和发展了现代公司财务理论。

Researchers of Song verses have often proposed the rules to describe the poetic composition, but few have focused on the interactions between verse language and music. Therefore, the aim of the study attempts to explore how music and the linguistic requirements are related in Jiang Kuei's seventeen verses.

宋词研究学者提出许多词律上的规定与特色，然而有关宋词词调之间的互动研究仍相当缺乏，因此本研究旨在探讨北宋词人姜夔的十七首自度曲当中语言形式的规定与音乐的关系。

Nowadays the scholars of other countries have developed many algorithms,this dissertation sums up these classical traffic incidents detection algorithms and indicates that these algorithms are mostly based on other countries freeways' detection data and their main limitation is that the algorithms are lack of replantable and auto-adaptable, while our freeway has great differences with other countries in traffic flow, traffic makeup and road establishment and so on.

目前各国学者已开发出各种检测算法，本文在总结常用交通事件检测算法的基础上指出这些事件检测算法大都是基于国外道路的检测数据，且其主要缺陷表现为缺乏可移植性和自适应性，而我国道路在交通流量、道路交通组成以及道路设施等方面与国外有较大的差别，如果直接将这些方法应用于我国高速公路事件检测，检测效果不会很理想。

Since the plate tectonic theory was introduced into China in 1970's, aulacogen has been considered in the area of Helan Mountain in Ordos Basin by some geologists. It is believed that Helan Mountain, Qinling and northern Qilian area were at the stage of rifting development from Mid-Neoproterozoic to Early-Mid Cambrian, and that Qinling, northern Qilian, Helan Mountain formed a trifurcate rift valley system.

自19世纪70年代板块构造理论引入中国后，一些学者把拗拉槽一词赋予了鄂尔多斯盆地西缘贺兰山地区，并认为贺兰山、秦岭、北祁连中新元古代至早中寒武世为裂谷发育阶段，秦岭、北祁连、贺兰山构成了三叉裂谷系。

"Tropicalization," first conceived in Levis Strauss'"Tristes Tropiques," has been employed by scholars of Latino studies to indicate the cultural contact, travel, translation, and transformation across the United States and its border of the South.

「热带型塑」一词源自於李维史陀的《热带的忧郁》，后来被拉美研究学者用於研究美国和拉丁美洲之间的文化接触、翻译、与移转。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
