摘　　要：电气石具有永久性的自发电极,其微粒的周围存在着以c轴轴面为两极的静电场。永久性自发极化效应使其具有热电性、压电性、天然电极性、辐射红外线、释放负离子等性能。开发电气石的功能属性,将其应用于环境保护、医疗保健、电磁屏蔽等领域,将产生巨大的经济和社会价值。该文章对电气石自发极化效应的研究进展进行了概述和总结,并在前人研究的基础上提出了电气石的相关应用前景及发展思路。The tourmaline has a permanent spontaneous electrode, around the particles exist a c-axis for the bipolar axial electrostatic field. The effects of permanent spontaneous polarization make it have pyroelectricity, piezoelectricity, natural electrode and infrared radiation, the release of negative ions and so on. Development of functional properties of tourmaline will be applied to the areas such as environmental protection, health care, lectremagnetic shielding, and will have tremendous economic and social value. In this paper, tourmaline research progress on the effect of spontaneous polarization will be given a overview and summary, and based on previous studies the relevant application of tourmaline prospects and direction of development will be thinking.
