[求助] 名词定义分析

Four series of Mo 2FeB 2 based cermets with the Mo/B atomic ratio in the range from 0.8 to 1.1 were prepared by reaction sintering process. The microstructure and crystalline phases were studied using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX) and X-ray diffractometry (XRD). The results indicate that the transverse rupture strength (TRS) of the cermets increases with an increase of Mo/B atomic ratio and shows a maximum value of 1.9 GPa at a Mo/B atomic ratio of 0.9. At a higher atomic ratio the TRS decreases. The hardness of the cermets decreases monotonically from 90.8 HRA to 88.8 HRA with an increase of Mo/B atomic ratio. In Mo-rich cermets with an atomic ratio of Mo/B above 1.0, a new M 23B 6 type phase (M 23B 6, where M represents a metal) is found. This phase has a lattice parameter a=1.09 nm containing Mo, Fe, Cr and B with an atomic ratio close to 16:6:1:6 and is precipitated at the interface of Mo 2FeB 2 grains or at the Mo 2FeB 2 grain boundaries.这段话中最后一句中 the interface of Mo 2FeB 2 grains和 the Mo 2FeB 2 grain boundaries的区别。谢谢

前者是晶粒之间的界面(包括取向相同或不同的界面;在本文主要是强调取向相同的晶粒界面),后者是晶界(特指晶粒取向不同的界面)。

楼主,可以把 ”前者是晶粒之间的界面(包括取向相同或不同的界面;在本文主要是强调取向相同的晶粒界面),后者是晶界(特指晶粒取向不同的界面)。“ 这一句话帮我翻译成英文吗? 我急需回复审稿意见。谢谢。。。。。。。
