例句與造句

1. When the sn atom at the top layer or sublayer is replaced by ti or ru , due to the lengths of ti - o and ru - o bond is smaller than that of sn - o bond , the obvious changes of the surface relaxations are observed with respect to the undoped one , especially when ti or ru substitutes for the six - fold sn atom at the top layer
   與未摻雜sno _ 2 ( 110 )表面相比,由于ti ? o或ru ? o鍵較sn ? o鍵來得短,當ti或ru取代表層或次表層sn原子后將引起表面弛豫的顯著改變,尤其是表層六配位sn被取代的情形。進一步的研究表明,摻雜后將產(chǎn)生新的表面態(tài),這將導致表面性質的改變。
2. It's difficult to find surface relaxation in a sentence. 用surface relaxation造句挺難的
