有三个角的

The comparison of the three noise values indicated that while the product of pulse width and angular frequency is larger than 1, the pulse width jitter would contribute considerable power to the total noise power spectrum, which is consistent well with the theoretical analysis.

比较三个噪声值表明了：在脉冲宽度角频率积Tω＞1的情况下，脉冲宽度抖动对总噪声量有较大贡献，脉冲宽度抖动不可忽略。

For the case of n=2 and X〓 is generic, by using Picard-Fuchs equations and the argument principle Horozov and Iliev [36] gave the least upper bound of the number of zeros of I under the condition that X〓 has one center and three saddles.

当n=2且X〓为通有的Hamilton系统时，Horozov和Iliev[36]利用幅角原理和Picard-Fuchs方程给出了当X〓有一个中心、三个鞍点时I零点上确界的个数。

The present author attempts to explore the nature of the mystery elements in his work by studying his masterpieces, The Scarlet Letter, The House of Seven Gables, and The Blithedale Romance, and other stories,"Young Goodman Brown","Roger Malvin's Burial", and "The Hollow of the Three Hills" etc.

通过分析霍桑的三部长篇小说《红字》、《有七个尖角阁的房子》、《福谷传奇》，以及短篇小说《好小伙布朗》、《胎记》、《罗杰·马尔文的葬礼》、《三丘之谷》等作品中的神秘因素，本文主要揭示了神秘因素的用途。

Hoxall genes from 16 vertebrates were analyzed, containing 10 cloned Hoxall genes mentioned above and 6 Hoxall genes from GenBank, Homo sapiens, Mus musculus, Bos taurus, Polyodon spathula, Heterodontus francisci, and Oryzias latipes, in representatives of the three major gnathostome lineages: cartilaginous fish, ray-finned fish and lobe-finned fish.

克隆的基因与从GenBank中获取的人、小家鼠、黄牛、匙吻白鲟、角虎鲨Hoxa11基因及青鳉Hoxa11a基因进行比较分析，这些动物代表了有颌类的三个谱系：软骨鱼类谱系、辐鳍鱼类谱系(斑马鱼、大黄鱼、花鲈、罗非鱼、红鳍东方鲀、乌鳢、青鳉和匙吻白鲟)和肉鳍鱼类谱系(矛尾鱼、热带爪蟾、绿背树蜥、家鸡、人、小家鼠和黄牛)。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

BR is embedded in the purple membrane and organized in trimeric unit arranged in a hexagonal twodimensional crystalline lattice, there are about 30 lipid molecules surrounding a BR trimer.

BR分子在紫膜中以三聚体的形式存在，并形成二维的六角型晶格，每个三聚体周围约有30个脂质分子。

Another village people 札 is prosperous to say:"Hide 历 mid- October in 1982, I lead river go to cloth dragon the ditch cut wood, after entering ditch smell a hoof Cape burnt bad smell, again go toward in walk a burst of, hear a rock a top 哗 suddenly 1, raise head and look, there are 2 to grow red hair of the monster stand in the mountain cave, I stunned, going toward hurriedly outside run, henceforth I got sick for 34 months."

另一位村民札旺说：&1982年藏历十月中旬，我过河去布龙沟砍柴，进沟后就闻到一股蹄角烧焦似的臭味，再往里走了一阵，忽然听到岩上哗啦一声，抬头一看，有两个长红毛的怪物站在岩洞口，我吓呆了，赶紧往外跑，此后我病了三四个月。&

Moreover, because there is a little difference between the optimized tripling detuned angle achieved by optimal THG efficiency and minimal temporal modulation, we should synthesis both two factors during optimum design.

此外，由于三倍频效率最优和时间调制度最小时对应的混频晶体失谐角略有差别，在优化设计时应综合考虑两个因素的影响。

We have one other pond just like this, White Pond, in Nine Acre Corner, about two and a half miles westerly; but, though I am acquainted with most of the ponds within a dozen miles of this centre I do not know a third of this pure and well-like character.

我们还有另一个这样的湖，在九亩角那里的白湖，在偏西两英里半之处；可是以这里为中心的十二英里半径的圆周之内，虽然还有许多的湖沼是我熟悉的，我却找不出第三个湖有这样的纯洁得如同井水的特性。

A representative from this alien species is a bipedal humanoid with blue-gray skin, double rows of cheekbones, a long, tapered proboscis, four conelets atop the skull, three-fingered hands, and a pair of dark, glassy eyes.

这个人形种族的代表性特征是：两足，皮肤灰蓝，双层的颊骨，尖细的长喙，颅顶生有四个锥角，手上三趾，眼睛黑色透明。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
