編輯意見:In section 3.1, the authors stated that according to the Cards of PDF in MDI Jade 5.0, the lattice constants of Al3Er and Al3Yb intermetallics are respectively 4.212 Å and 4.202 Å. Based on the above expression, it seems that the author did not refine their own XRD results, but citing the lattice constant values from the standard PDF Cards. However, in Table 1, the authors referred these values as their own experimental data, which is not the appropriate. I recommend the authors refine their own XRD results to obtain the corresponding lattice constants. 本人文章:Fig. 1 shows XRD patterns of the Al-10 wt.% Er and Al-10 wt.% Yb alloys. As shown in Fig. 1, there are two kinds of peaks in the XRD patterns of the Al-10 wt.% Er/Yb alloys, one is the peak of matrix Al and the other is for Al3Er/Yb intermetallic. According to the Cards of PDF in MDI Jade 5.0, the lattice constants of Al3Er and Al3Yb intermetallics are respectively 4.212 Å and 4.202 Å. 本人問題: I recommend the authors refine their own XRD results to obtain the corresponding lattice constants.我理解的意思是編輯讓我改善XRD結(jié)果,有點(diǎn)蒙,怎么改善?是讓我通過XRD的結(jié)果自己計(jì)算晶格常數(shù)么?請(qǐng)各位蟲友幫幫忙,小弟在此謝過了。 |

你在jade里把你的xrd數(shù)據(jù)和標(biāo)準(zhǔn)卡片比對(duì)上了,這個(gè)只能大致說明你的結(jié)構(gòu)和它很近,而你直接用了卡片里的晶格常數(shù),這個(gè)是不科學(xué)的,因?yàn)榫Ц癯?shù)會(huì)隨溫度、擇優(yōu)取向等變動(dòng)。尤其當(dāng)你用的兩個(gè)卡片只差0.01埃,其實(shí)同一種物質(zhì)的不同卡片(也就是不同人在不同條件下測的)可能都不只差這些。 所以審稿人要求你根據(jù)自己的xrd測得的數(shù)據(jù),去“算”出晶格常數(shù),也就是加入溫度、擇優(yōu)取向等一系列參數(shù)擬合出來,這個(gè)過程就叫精修,refinement。 再具體你可以搜一下相關(guān)資料,但友情提示一下,如果你完全不懂想要自己搞定精修這件事,在短時(shí)間內(nèi)應(yīng)該不可能,xrd數(shù)據(jù)可能也要重新測試。建議你找一下有沒有熟人懂的或者測試機(jī)構(gòu)做一下,收費(fèi)可能也不便宜。 發(fā)自小木蟲IOS客戶端 |
