[求助] 急！！！！！！求材料专业英语好的大神解释一下这段机理

At a high temperature (200 °C)and relatively long growth duration (5 h) in 1-butanol, the growth of nanocrystals is complete and the thermodynamically
favourable sphere-like Mn 3 O 4 nanoparticles are obtained,which is stabilized by some high Miller index facets, driven by autonomous minimization of the surface energy. According to the Wuff facet theory, the crystal growth should occur rapidlyon high-free-energy facets, resulting in crystals with low-freeenergyfacets. [ 25 ] Therefore, at a lower temperature (150 °C) and a shorter reaction time (3 h) in ethanol, the cube-like morphology is observed, which was stabilized with low Miller-index facets ((100), (010), and (001)).by 1-pentanol the high temperature (200 °C) with suffi cient growth duration (5 h), the crystal growth rate on high-free-energy facets increased because of the improved reactivity of ions in solution due to the decreased solvent polarity, resulting in more low-Millerindex facets, so ellipsoid-like nanoparticles were formed (sample NENG). [ 38 ] As a result,the ellipsoidal sample has the highest percentage of (001) facet, which features the lowest surface energy in three samples. [ 39 ]

尤其求解释什么是wuff facet theory???
