小蟲子在這里弱弱地問一下:Le Bail Fitting 是怎么回事?
|
|
今天第一次遇到這個(gè)名詞,看的書上也沒有提到這個(gè)(或許沒看到)…… Le Bail fitting對(duì)應(yīng)的中文翻譯是什么?在哪些書上有相關(guān)的內(nèi)容?它大致的內(nèi)容和作用是什么? |

Armel Le Bail是個(gè)人名,他發(fā)明的一種擬合方法。就是 Le bail fitting To overcome some of the problems of theSample Text as experienced at the time, Sample Texttook a wholly different approach to the extraction of the peak intensities from the powder profile. The approach was simple and, perhaps more importantly, it was very easy to code into existing Rietveld programs. Armel Le Bail’s idea: can the Rietveld extraction method be used to estima reflection intensities even without a structural model? the answer :YES Sample Text |

LeBail Method To overcome some of the problems of the Pawley method as experienced at the time, Armel le Bail took a wholly different approach to the extraction of the peak intensities from the powder profile. The approach was simple and, perhaps more importantly, it was very easy to code into existing Rietveld programs. The method uses a two-step cyclic process. As with the Pawley method, the following parameters are fitted by a standard least-squares methods: A,B,C,D,E,F - Unit-cell metric tensor parameters; 2θzero - Instrumental zero error; U,V,W - Peak-width parameters; η, etc. - Other peak-shape parameters. |
