| 摘 要： | 用扫描电子显微分析手段研究电气石微粒的运动行为、影响因素,为评价电气石自发电极性提供新方法.结果表明,在SEM下用二次电子(SE)电子束轰击电气石微粒,电气石微粒产生自迁移现象,迁移距离与自发极化强度、微粒粒径、极性轴方向等因素密切相关.提出通过测量自迁移距离评价电气石电极性强弱的新方法.

| Abstract: | The motion behavior of the mineral tourmaline particles and influence factors were studied by scanning electron microscope (SEM) in order to supply a new method of assessing the poles characteristic of tourmaline. Test results show that by secondary electron's (SE) electron-beam bombardment under the action of SEM,the tourmaline powder will migrate spontaneously .The migration distance is closely related to the spontaneous polarization, the size of particle and the direction of polar axis. This paper described an assessment approach for the poles characteristic from the measurement of migration distance. |
