查询词典 in excess

This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

首先，本文从理论上对坩埚下降法生长碲锌镉单晶体中的成核、Zn分凝、几何淘汰生长与温场等关键性问题进行了讨论，对在生长过程中可能出现的各种缺陷类型和形成原因进行了详细分析，提出了碲锌镉单晶体生长过程中Cd空位缺陷控制原理及方法，并针对坩埚下降法生长特点自行设计了两区域独立加热管式生长炉，获得具有较好线性分布的温场。

The third part of this thesis is reactive simulating calculation In this section, some well-known auxiliaries are selected to compute in density functional theory B3LYP on Gaussian 03, from which the relationship between reaction active energies of transition states and enantiomeric excess of chiral products homoallylic alcohols isobtained based on relative reactive ratio theory. Using this relationship, calculations on the reaction of more than eight auxiliaries with four other aldehydes are carried out in AMI and MNDO, proving that N,N\'-dibenzyl tartamide has higher enantioselectivity than others in this reaction.

第三部分为计算化学部分，运用密度泛函理论B3LYP方法在Gaussian03软件上对已经报道的几种手性配体参与的醛不对称烯丙基化反应过程进行模拟计算，基于相对反应速率理论找出两种构型过渡态间活化能的差异与产物光学收率之间的关系；并以此为基础，用AM1和MNDO方法对上述合成的几种配体控制的反应过程进行量化计算，从而在理论上证实了N-苄基酒石酸二酰胺配体在醛的不对称烯丙基化反应中具有较高的立体选择性。

It is argued that the interplay of lack and excess in Pai Hsien-yung results in a metonymical narrative of desire in which relations of the subject and the object can never be reciprocal and thus are destined to be reenacted in an endlessly renewable cycle of appetite and anxiety in the storytelling process.

二者之间的吊诡关系正说明了白先勇的欲望叙事建基於主体与客体的永远无法交融，只能是一波推向一波的欲望徵逐，一个永无止尽及无偿的循环。这欲望的徵逐循环在白先勇不但是个主题，更是促生整个叙事活动的原动力。它不但决定了叙事发展的模式，也启动了每次书写的开端。

Within the limits of genera, most of the parts as a rule exhibit differences through contrast of the property or accident, such as colour and shape, to which they are subject: in that some are more and some in a less degree the subject of the same property or accident; and also in the way of multitude or fewness, magnitude or parvitude, in short in the way of excess or defect.

在属的范围内，大多数部分通常都通过属性或意外的对比表现不同；例如他们从属的颜色和形状，在属性中，动物在同一属性中程度不同，有的多，有的少；同样适用于多或少大或小，简短说，就是在优点和缺点方面。

The surprising excess death rate in patients randomized to tenecteplase plus angioplasty led to premature termination of the trial; less than half of the planned 4,000 patients were enrolled, said Frans Van de Werf, MD, chairman of the cardiology department of the University Hospital Gasthuisberg in Leuven, Belgium. Dr. Van de Werf told Medscape that an increased rate of major bleeding and strokes in the thrombolytics group cannot fully explain the difference in mortality."We're not sure what is going on," he said."Had we selected more experienced cardiologists or more experienced centers for one group?"

在随机分配下，接受tenecteplase加上血管修复术治疗的患者，因为产生令人震惊的超高致死率，这项试验於是提前终止；在比利时鲁汶盖斯堡教学医院心脏病学部的院长Frans Van de Werf医学博士向Medscape表示，原先预期的试验参与者有4千名，只有不到不到一半愿意接受这项试验；溶解血栓剂组有著偏高的大量出血与中风现象，但这并无法解释这一组患者的高死亡率；Van de Werf表示，我们无法确定到底发生了什麼事，难道另外一组的医师与临床中心较有经验？
