atomic structure 原子構造。

atomic value

In order to improve the properties of materials , one needs to understand the structural relationship between interface and matrix of the materials , such as interface atomic structure , misfit dislocation , chemical bond structure , stress field distribution , composition segregation etc . there are tremendous research works on the grain boundary and interface structures during last century and the sophisticated theory about grain boundary and interface , i . e . coincidence site lattice and 0 - lattice theories had been developed simultaneously 眾所周知,材料的宏觀性質是由其微觀結構所決定的,因此,為了改善材料的宏觀性能我們有必要弄清楚材料的界面與基體之間的結構關系,如界面的原子結構、失配位錯、化學鍵合、應力場的分布等等。在上世紀,人們已對晶界和相界面結構進行了大量的研究,同時,相關的理論如“重位點陣”和“ o -點陣”理論也發展成熟。

One of the very basic results of the physics and chemistry of solids is the insight that properties of solids depend on the microstructure , i . e . the chemical composition , the arrangement of the atoms ( the atomic structure ) and the size of a solid in one , two or three dimensions 20世紀80年代,人們把尺度小于100nm并且具有特異物理性能和化學性能的粉體材料定義為納米粉體材料。我們知道,固體的性質和固體的微結構、化學組成、原子排布以及固體在不同維數中的尺度有著密不可分的關系。

Using the methods of systematism the author treats the technovation subjects as a system and analyzes the different objectification process of the tchechovation subjects in respect of different innovation stages specifically . moreover , the atomic structure , the ability structure , the age structure and the speciality structure of technovation subject are discussed in great detail , and the function of it is expounded . the thesis thinks that the technovation subjects are the key for enterprises to develop through technovation activities , their quality and gradation determine the level of achievements , and their conscious creativeness of technovation subjects is the soul of technovation activities 本文從哲學的角度對技術創新主體問題進行了初步的綜合性研究,論述了技術創新主體的概念、基本特征,明確提出技術創新主體是與創新客體相對應的范疇;用系統方法對不同創新階段創新主體的對象化活動過程進行了具體分析;詳細討論了技術創新主體的核式結構、能力結構、年齡結構和專業結構;闡述了技術創新主體的功能,認為技術創新主體是企業通過技術創新活動獲得發展的關鍵,其素質和層次決定技術創新成果的水平,其意識創造性是創新活動的靈魂。

Thirdly , basic approaches of molecular dynamics simulation , which include building the model potential , potential truncation , short - range interaction computations , integration methods , boundary conditions and so on , are studied in detail . they are discussed in detail which include preparations for data before simulating , control method during simulating , different factors related to equilibration of simulating systems , observation of atomic structure after simulating , statistic and control methods of macro characters 再次,深入研究了分子動力學模擬的基本算法,包括物理建模、勢能截斷、計算短程作用力的方法、時間求積算法和邊界條件問題等,并詳細討論了分子動力學模擬前的數據準備工作、運行時的控制方法、影響系統達到平衡狀態的各種因素和模擬后對原子結構的觀測以及宏觀特性的統計控制方法。

Buckminsterfullerene and its elongated cousins the carbon nanotubes or buckytubes were discovered , it suddenly became clear that our understanding of many factors governing the atomic structure of carbon and other materials was quite na 作為化學及物理的邊緣學科,以及在另一邊緣學科的化學和生物學開始變得不能區別,多學科研究正在使納米科學及納米技術(不要將納米科學技術固體力學和材料工程相混淆)成為令人神往的新領域。

Together with scientists at the ibs they isualized the atomic structure of the protein and discoered a preiously oerlooked signal that labels it for transport to the human nucleus where the genetic material of the irus is replicated 它只是整個蛋白質的一小部分,但是它使我們領悟到蛋白質是如何工作及它的突變株是怎樣影響到宿主范圍的

An atomic smictufal model for c ( 2x2 ) reconstruction is proposed and a total energy calculation illustrates that the hollow - site - occupied si adatom model might be a possible atomic structure of the c ( 2x2 ) reconstruction 光電子發射譜被用于研究界面形成過程中出zp 、 hf4f芯能級譜和價帶譜,以及功函數等的變化。

Democritus was one of the earliest philosophical materialists and speculated about the atomic structure of matter . marx ’ s first published word was a study of democritus 德謨克利特是最早的唯物主義哲學家之一,也是最早的原子論創始人之一。馬克思發表的第一部哲學著作就是以德謨克利特的思想為研究對象的。

Amorphous materials have disordered atomic structure as compared to crystalline materials : that is , they have only short - range order rather than the long - range periodicity of crystals 與晶體材料相比,非結晶體材料使原子結構發生無序變化,即:它們只有晶體的短程序列特征,而沒有晶體結構的長期周期性特征。

Chemists had no less astonishment as they recognized in these radioactive bodies , elements which had undergone modifications of the atomic structure which had been thought unalterable 化學家們對他們在放射體中發現的元素同樣感到驚奇:這些元素經歷了原子結構變異,而原子結構一直被認為是不可變的。

The relativistic multi - configuration dirac - fock ( mcdf ) method is one of the best widespread used methods in the calculation of atomic structures and properties 多組態dirac - fock ( mcdf )方法是一種在相對論理論框架下發展起來的廣泛用于計算原子結構和性質的理論方法。

The only thread running through the values is that if many of them were even slightly different , complex atomic structures such as living beings would not be possible 它們唯一共通之處是,如果這些常數值稍有變化,類似生物體這種由原子組成的復雜結構,便不可能出現。

Diamonds were formed under intense heat and pressure , and traces of other elements may have been incorporated into their atomic structure accounting for the variances in color 鉆石在高壓高熱中形成,痕量的其它元素被裹入其原子結構中便會形成各種各樣的顏色。
