查询词典 peaks

Firstly, the incommensurate magnetic scattering of the doped single-layer triangular lattice in the normal state has been studied. It is shown that away from half-filling the commensurate peak is replaced by six incommensurate peaks located at [ (1-δ〓), ] , [ (1-δ′〓), ] , [ (1-δ"〓), ] , respectively, and 〓〓. The incommensurability parameter δ increases with doping at lower doping concentration, while saturates at higher dopings. These peaks broaden and weaken in amplitude with increasing energy and temperature, with the positions of the incommensurate peaks not changing with the energy.

利用t-J模型，讨论了单层和双层三角晶格材料的非公度磁散射，结果表明：随着掺杂的增加，三角晶格反铁磁体出现公度-非公度转变，即由一个公度峰变为六个非公度峰，并且非公度率在较低掺杂时随着掺杂浓度的增大而增大，在较高掺杂浓度时将达到饱和；虽然非公度峰的权重随着能量的增大而减小，但非公度峰的位置与能量无关，即非公度率是不随能量变化的，并且我们还发现非公度峰的权重随着温度的升高也是减小的。

The experimental results show that: DNA of normal gastric mucosa has stable phosphate backbone; Since the peak intensity at 1090 cm^(-1) is lower than that at 1050 cm^(-1), phosphate backbone in DNA of intestinal metaplasia becomes unstable, while the rest spectra peaks are similar to those in normal gastric mucosa; In terms of adenocarcinoma DNA, double peaks at 1090 cm^(-1) whose intensity are higher than 1050 cm^(-1), are observed, which indicates that DNA chain is broken and re-forms a double stabilized phosphate backbones. In addition, peaks at 950 cm^(-1), 1010 cm^(-1), 1100~1600 cm^(-1) also exhibit obvious difference compared with normal gastric mucosa, which shows that deoxyribose and bases are changed due to broken of DNA.

实验结果表明，胃粘膜正常组织DNA中有稳定的磷酸骨架；肠化组织基因组DNA拉曼特征峰在1090 cm^(-1)处谱峰强度低于1050 cm^(-1)处谱峰强度，表明其磷酸骨架变得不稳定，其它位置的谱峰与正常组织相似；腺癌组织基因组DNA拉曼特征峰在1090 cm^(-1)附近出现双峰，其相对于1050 cm^(-1)处谱峰强度更强，提示DNA有可能出现断链并再次形成了稳定的磷酸骨架，在950 cm^(-1)、1010 cm^(-1)、1100~1600 cm^(-1)波段的特征谱峰与正常组织DNA相比变化也较大，说明脱氧核糖和碱基可能由于DNA断链也随之改变。

They were within fifteen miles of Monte Cristo when the sun began to set behind Corsica, whose mountains appeared against the sky, showing their rugged peaks in bold relief; this mass of rock, like the giant Adamastor, rose dead ahead, a formidable barrier, and intercepting the light that gilded its massive peaks so that the voyagers were in shadow.

当他们离基督山只有十五哩的时候，太阳开始沉落到科西嘉的后面，科西嘉的群山在天空的衬托下划出明晰轮廓，雄劲地呈现出峥嵘的山峰。这座大岩山象巨人亚达麦斯脱似的气势汹汹地俯视着小船，遮住了太阳，而太阳又染红了它的山巅。

We have found that there are regularity changes in the Raman spectra of grossular-andradite as the rise of iron in the crystal structure from grossular to andradite after studying of Raman spectra of grossular-andradite, that is to say, their peaks shift to low wavenumber; At the same time , there are some changes in the bond angles of O-Si-O and O-Y-O:the higher of iron contents, the evidenter of splitting of two wind vibration peaks of SiO4 tetrahedron and YO6 octahedron.

通过对钙铝榴石-钙铁榴石的拉曼光谱研究发现，从钙铝榴石到钙铁榴石，随着矿物结构中铁的含量的增加，他们的拉曼光发生规律性的变化，即所有的峰向低波数方向发生漂移；同时，由于铁含量的不同使得石榴石晶体结构中O-Si-O与O-Y-O之间的键角发生了一定的变化，在其拉曼光谱谱图上表现为铁的含量越高，[SiO4]四面体和Y-O八面体的两个弯曲振动峰分裂得越明显。

X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

We did not find the same ultraviolet cathodoluminescence peaks with natural diamonds, and believe that they may be characteristic peaks and valuable fingerprints of Chatham synthetic diamonds.

这些紫外阴极发光谱在天然钻石和人工处理后的天然钻石中都没有发现，可能是Chatham合成钻石的特徵谱，因而可能具有一定鉴定价值。

The IR spectra of NDA-800 and NDA-90 resins showed that there only small changes of the wavelength and strength of the characteristical adsorption peaks took place and without new peaks appearing after they were loaded with phenol, salicylic acid, p-hydroxybenzoic acid and 2, 6-bihydroxybenzoic acid.

The valley ran from the horseshoe, land- locked bay to the tops of the dizzy, cloud-capped peaks and contained perhaps ten thousand acres. It was filled with tropical fruits, wild chickens, and wild pigs, with an occasional herd of wild cattle, while high up among the peaks were herds of wild goats harried by packs of wild dogs.

那道峡谷从被陆地包围的马蹄铁形海湾开始直到白云缘绕的令人晕眩的峰顶，约有一万英亩，满是热带水果、野鸡、野猪，偶然还会出现野牛群。

Even in the good cause of conservation he was loud, bloody loud, in his unmodulated Strine. And he was naive in a wide-eyed, right-wing way, almost genuflecting to John Howard as he called him "the greatest leader in the entire world".

他就用他那不经修饰的土著嗓音大声呼吁着环保，从他的眼睛中，右翼行为方式，称澳大利亚总理约翰霍华德是"世界上最伟大的领袖"时那种尊敬中可以看出他的孩子气。
