| 摘 要： | 营口玉是传统岫岩玉中的特别类型,它的物理化学特征及成矿类型均与传统岫岩玉不同。采用ETS-2能量测试系统、偏光显微镜、电感耦合等离子质谱仪等现代测试技术手段对营口蛇纹石玉负离子释放量及机理进行了研究。结果表明:营口蛇纹石玉具有很好的负离子释放功能(840～933个/cm3),接近都市公园水平(1 000～2 000个/cm3),甚至高于环境矿物材料电气石。营口玉释放负离子的根本原因是玉石内部放射性微量元素导致空气分子及水分子电离而产生负离子。具有生物和化学活性的蛇纹石与玉石内具有放射性的微量元素共同作用使营口玉具有较好的负离子释放功能。

| Abstract: | Serpentine jade from Yingkou is a special kind of traditional Xiuyan jade. Its physicochemical characteristics and metallogenic type are considerably different from those of Xiuyan jade. In this paper, the negative ion emission function and mechanism of Yingkou serpentine jade were investigated using the modern analytical techniques such as ETS-2 Energy Measurement system, polarizing microscope and ICP-MS. It is found that the serpentine jade from Yingkou has a good function of releasing negative ions whose concentration is similar to that in the city park and higher than that of tourmaline, which is regarded as an excellent environment material. The negative ions are generated because of the ionization of surrounding air and water which is caused by the radioactive elements in the serpentine jade. The serpentine with biological and chemical activity and the radioactive trace elements in the Yingkou jades work on the air and water and consequently generate high quantity of negative ions. |
