從文獻(xiàn)上看到某納米粒子的直徑隨原料濃度的增長而增長,而其平均粒徑卻與原料濃度的濃度無關(guān)。(納米粒子直徑diameter和平均粒徑average grain size有什么關(guān)系?分別是什么?) 這是原文: Therefore, it can be concluded that the diameter of Fe3O4 microspheres increased with Fe3? concentration, whereas the average grain size of Fe3O4 microspheres was irrespective of Fe3? concentration. Here larger amount of Fe3O4 nanoparticles can be formed with the increase in Fe3? concentration, leading to the larger diameter of Fe3O4 microspheres, whereas the average grain size of Fe3O4 microspheres is supposed to be related to surfactant, which is the same in this set of samples [ Last edited by 帥博士 on 2010-6-6 at 20:30 ] |
