查询词典 theta function

The first year of this project studied the sintering behavior of sub-micron .theta.-alumina powders. After forming using cold isostatic pressing, green specimens were heat treated at various temperature and time. The pore size distribution, density, phase transformation, and microstructure were analyzed using mercury porosimeter, XRD, SEM.

中文摘要本计画第一年进行次微米之θ相氧化铝粉末的烧结行为研究，粉末以冷均压成型后以不同之温度及时间进行热处理，坯体/烧结体以水银孔隙仪、XRD及SEM等仪器，分析其孔隙分布、密度、相转换量、微结构等。

They were mainly of pretibial or pretibial/Pasini mixed type. With two-point linkage analyses, Alu I and Msp I polymorphisms were not informative for all families. Pvu II polymorphism was informative in 2 families with a combined lod score of 1.593 at .theta.

我们对其中的6个以胫前型表现的DEB家族进一步用Intrageic Puv II及Flanking Msp I，Hind III pelymorphic markers作Two point及Multi-point连锁分析，结果用两点连锁分析，只有两个家族的Puv II marker是Informative ，合起来得到Z=1.593，。theta。

The liquid crystal display has a chiral ferroelectric smectic liquid crystal between two transparent plates with electrodes for generating an electric field, and polarisers in front of and behind the liquid crystal, the ratio d/p of the thickness d of the liquid crystal layer to the pitch p of the helical twisting being larger than 5, the smectic tilt angle theta 0 being between 22.5 DEG and 50 DEG , and the product d.

一种液晶显示单元，它具有：一种在两块透明平板之间的手性铁电近晶液晶；用于产生电场的电极；在液晶前后各有一偏振片，液晶层的厚度d与螺距扭曲的螺距高度p的比值d／p大于5，近晶倾角θ 0 为22.5～50°，厚度d、倾角θ 0 的平方、双折射率△n和光波长λ倒数的乘积dθ 2 0 △n1/λ大于0.45μm。

Furthermore, within such REM episodes behavior-dependent modulation of the subcortically driven theta rhythm is also reproduced.

此外，在REM事件中行为依赖的皮下层诱导的θ节律的调节也再生了。

In this paper, after the similarities and differences of the three theories on semantics, including Valent grammar, Case grammar, Theta theory, are reviewed synoptically, we introduce a semantic model based on phrase-standard grammar of contemporary Chinese for a Chinese-English machine translation system.

本文在简略阐述我们对几种语义分析理论——配价语法，格语法，论旨理论的认识的基础上，介绍我们研制的一个基于汉语词组本位语法的汉英机器翻译系统所采用的语义模型。

I will suggest that this is because nouns are not governors, and government is required for theta-marking.

我认为，这是因为名词不是统领词，而统领是题元指派所要求的。

The next states, theta brainwaves, are typically of even greater amplitude and slower frequency.

下一个状态时θ脑电波，代表更大的振幅和更小的频率。

Methods Basolateral amygdala slices of rats were prepared. Field excitatory post-synaptic potentials of BLA were recorded by stimulating the external capsule. Two TBS's were applied to induce LTP in BLA. Each TBS included a brief, high-frequency pulse train (5 pulses at 100 Hz) given at the theta-rhythm (5Hz) for 4 seconds. Experiments compare the effects of different intervals of two TBS's on the expression of LTP in BLA.

制备杏仁核脑片，刺激外囊记录BLA场电位，应用两串θ频率波刺激诱导LTP，每串θ频率波刺激为20个(频率5Hz)短时间高频串脉冲(5个脉冲，频率为100Hz)，通过改变两串θ频率波的刺激间隔，分析不同参数诱导的LTP是否存在差异，并在灌流的人工脑脊液中加入TPK抑制剂genistein，观察其对杏仁核LTP的影响。

A varifocal f-theta lens was designed for Nd:YAG laser making scan focusing system, so that it apply to differ making area but change a lens necessarily. the system consists of four lens ,made by glass BK7, SF18 and SF11. The total length of the system is 122.96mm, working at 1064m.

为Nd：YAG激光打标机设计了变焦距f-theta镜扫描系统，以使它适用于不同的打标面积而不必更换镜头，系统由四片透镜组成，材料分别为BK7，SF18和SF11，系统总长度为122.96mm，工作波长1064nm。

"In sleepwalking you are half asleep and half awake," says Carlos Schenck of the Minnesota Regional Sleep Disorders Center at the University of Minnesota Medical School,"The brain produces delta waves and theta waves, which really demonstrates that the person is in a twilight state."

梦游病是在半睡着半醒的情况下形成的，在明尼苏达医学院大学里的Carlos Schenck说尼苏打地方是失眠中心，哪些真正地显示出，人是在一个暮色状态里脑子生产三角洲波浪和希腊字母的第八字波浪。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
