晶格不對稱 的英文怎麼說
中文拼音 [jīnggébùduìchèn]
晶格不對稱
英文
crystal lattice asymmetry-
Then the structure unit of hexangular lattice is found according to the principle of invariable symmetry. renormalization transformation is processed when we regard the structure unit and the growth model as graphs before and after transformation respectively. after choosing the 11 thermodynamic function fugacity as parameter, we can write out the partition functions before and after transformation and the formula of renormalization transformation
然後根據對稱性不變的原則，從整體晶格中選取結構單元，把結構單元和生長模型分別作為重整化變換前、后的圖形來進行重整化變換，選取熱力學函數易逸度為參量，寫出了重整化變換前後的配分函數和重整化變換關系式，求出了這一變換的不動點。Consisting of the protracting graph of hydrogen - like atom ' s angle distributing, computer simulation of the symmetry of molecular orbital and chemical reaction mechanism, showing the molecular point group and symmetry element, computer simulation of molecular vibration, bravias ' s crystal lattice and their transforming, extracting of plane periodic lattice, extracting of solid periodic lattice, close packing of isometrical pellet and the structure of simple mental substance, close packing of unequal pellet and crystal structure of representative ionic crystal, computer simulation of phase analysis by x - ray diffraction
內容包括類氫原子角度分布圖的繪制，分子軌道對稱性和反應機理的微機模擬，分子點群和對稱元素顯示，分子振動運動的微機模擬，布拉維晶格和晶格轉化，平面點陣抽取，立體點陣抽取，等徑網球的密堆積和金屬單質結構，不等徑圓球密堆積和典型離子晶體結構， x射線多晶衍射的微機模擬十個子模塊。Based on many other circuit formats, a new kind of logic - level circuit representation, called unified middle - level circuit format ( umcf ), is defined in this paper, in which some special operations on circuit related with power estimation and low power design. umcf can not only interchange circuits of different formats, but also convert circuits to hspice acceptable files, which can be used for transistor level power estimation
本文結合多種不同的電路格式，自主定義了一種邏輯級電路的中間表示形式（稱為umcf ）和一系列極具特色的與低功耗技術相關的操作，它不但可以實現與其他多種電路格式之間的相互轉換，還可以將電路直接轉換成hspice可以接受的文件，進行晶體管級的電路功耗估計，這樣可以在公認的高精度的功耗模擬器上，對本文的結果進行有效的驗證。The investigation of structure by x - ray diffraction shows that crystal parameters changes clearly when percenting ca and la into pbtio _ 3, it was caused by the ca ion and la ion replaced the pb ion of a position in perovskite compound, that bring lattice mismatch and asymmetrical replace
在pbtio _ 3中摻入la和ca可以有效改變薄膜的晶格常數，這是因為在abo _ 3型化合物中，鈣離子、鑭離子取代了a位的鉛離子，造成晶格失配和不對稱取代。In the selection of kadanoff cells a new idea is given, i. e., not only the symmetry of lattice before and after selection must be kept unchanged, but also the coordination number must be kept unchanged
在kadanoff集團的選取上本文提出了一個新觀點，即不但要保持選取前和選取后晶格的對稱性不變，還要保持格點的配位數不變。So a hypothesis is proposed, i. e., as long as the symmetry and coordination number are kept unchanged the critical behavior of any two - dimensional lattice is same by this method. that indicate those two - dimensional lattices belong to the same universal class
所以本文還提出假設，只要是保持對稱性和配位數不變，用這種方法計算出的任何二維晶格的臨界行為都是相同的，這表明它們是同一普適類。分享友人
