We applied atomic force microscopy (AFM) for the observation about surface structure of the following five polycrystalline materials, BaTiO_3, NaKC_4H_4O_64H_2O (Rochelle salt), WO_3, PbTiO_3 and Bi_4Ti_3O_<12>.For multi-domain samples of BaTiO_3, NaKC_4H_4O_64H_2O and WO_3, temperature dependent surface images were investigated. Namely, the topographic images in the creation and disappearance process of 90 degree domains in BaTiO_3, monoclinic domains in NaKC_4H_4O_64H_2O and triclinic domains in WO_3 were taken with variation of temperature including their phase transition tmepratures.For PbTiO_3 and Bi_4Ti_3O_<12>, the crystallization processes from the amorphous state were investigated. The initial state of these samples is in the amorphous state prepared by rapid quenching. The topographic images in the crystallized samples by annealing at several different temperatures were taken. In this case, the visualization of the surface hardness was also made using the force modulation mode.

我们应用原子力显微镜（AFM）对BaTiO_3、NaKC_4H_4O_64H_2O（罗谢尔盐）、WO_3、PbTiO_3和Bi_4Ti_3O_<12>五种多晶材料的表面结构进行了观察。对于BaTiO_3、NaKC_4H_4O_64H_2O和WO_3的多畴样品，研究了与温度相关的表面图像。即BaTiO_3中的90度相域、NaKC_4H_4O_64H_2O中的单斜相相域和WO_3中的三斜相相域在温度变化（包括相变温度）下的形貌图像。对于PbTiO_3和Bi_4Ti_3O_<12>，结晶过程从非晶态进行了研究。这些样品的初始状态是通过快速淬火制备的非晶态。通过在几个不同温度下退火获得结晶样品的形貌图像。在这种情况下，表面硬度的可视化也是使用力调制模式进行的。
