采用硬酯酸法合成了ＢａＴｉＯ３纳米晶材料（１８～８０ｎｍ），在０～１．５ＧＰａ的压力范围内考察了压力对材料性能尤其是对湿度敏感性能的影响，并用ＸＲＤ、ＩＲ等手段对材料的压力效应进行了表征
The BaTiO3 nanocrystalline materials (18 ~ 80nm) were synthesized by the stearic acid method. The effects of pressure on the properties of the materials, especially the humidity sensitive properties were investigated in the pressure range of 0 ~ 1.5GPa. The pressure effect was characterized
