[求助]
求助析出相晶體學(xué)中“singular interface”怎么翻譯。
|

“A general approach for investigating the crystallography of precipitation is developed from a systematic analysis of interfacial structures. The central hypothesis in this approach is that a habit plane or major facet developed in a precipitation reaction is the physical realization of a singular interface.” 各位高手,上面這段話中的“singular interface”應(yīng)該翻譯成什么比較合適,敬請(qǐng)指教。 |

The classification made by Balluffi and Sutton has proved to be particu-larly useful in describing interfaces. According to their definition,interfaces consist of three types: singular, vicinal and general. A singular interface is ‘‘a(chǎn)n interface, the free energy of which is at a local minimum with respect to at least one macroscopic geometrical degree of freedom’’; a vicinal interface is ‘‘a(chǎn)n interface, the free energy of which is near a local minimum with respect to at least one of the macroscopic geometrical degrees of freedom’’; a general interface is ‘‘a(chǎn)n interface, the free energy of which is at, or near, a local maximum with respect to one or more macroscopic geometrical degrees of freedom’’. Here, the term ‘‘macroscopic geometrical degree of freedom’’ is a degree of freedom in a five dimensional boundary geometrical phase space (5D BGP space). “singular interface”是低指數(shù)面(低表面能)的意思嗎? |

確實(shí)是指能量的極小值對(duì)應(yīng)的界面。稱為 奇異界面。這個(gè)能量的極小值是指相對(duì)于界面五維空間中至少某一維 的極小值。典型的是晶界能量對(duì)應(yīng)于晶界取向連續(xù)變化的曲線,在sigma3 sigma5等處取得極小值。 PS 樓主看的是清華張文征老師的文章吧? |
