commensurate和incommensurate的定義
|
|||
|
跟大家討論討論commensurate(公度)和incommensurate(非公度)的定義。 最近調(diào)研這方面的書和文章都沒有發(fā)現(xiàn)對(duì)這個(gè)概念的一個(gè)統(tǒng)一個(gè)定義。有文獻(xiàn)中說公度(不公度)相是一種在基本晶格上的附加某種公度(非公度)調(diào)制產(chǎn)生的,也有的說是由于存在兩個(gè)不同晶格標(biāo)尺的相互競(jìng)爭(zhēng)產(chǎn)生的,不知大家有什么見解? |

我最近對(duì)這個(gè)挺感興趣的 這個(gè)網(wǎng)頁我覺得挺有用的 http://www.laex.org/stuart/thesis/node7.html |

Three types of hetero-phase interfaces are generally considered: coherent or commensurate, semi-coherent (or “dis-commensurate”) and incoherent or incommensurate. 應(yīng)是共格、非共格。 A coherent interface arises when the two crystals match perfectly at the interface plane so that the two lattices are continuous across the interface. Whatever the chemical species, the interface plane has the same atomic configuration in the two phases, requiring the existence of a preferential orientation relationship between the two crystals. An incoherent interface generally results from a random orientation relationship between the nucleus and the matrix. But, it may also appear between crystals displaying a preferentialmisorientation if the interface plane is random (analogy with a grain boundary where, for a given coincidence, the plane may be symmetrical or not, constituted of dense planes or random planes of the crystals). |
