火山岩中碱长石有序化途径的X射线研究 总被引:1,自引:0,他引:1
本文用X射线粉末法对某些火山岩地区的碱长石有序化途径进行了研究。根据文献资料用数理统计法重新作出一系列用X射线数据求铝占位的公式和图表,并以Thompson系数Y,Z作数学模拟,提出模拟函数Y=Z~k。称k为有序化途径指数。从各火山岩盆地中碱长石的k值上确定有序化途径的差异性,并结合火山岩岩石学研究成果作出一些初步的成因结论。 相似文献

用一种新型超支化氟化聚酰亚胺(FHBPI)作为波导材料制备了聚合物热光开关. 采用DSC, TGA, 近红外吸收谱和原子力显微镜(AFM)等方法对FHBPI的热稳定性及光学特性进行了表征. 结果显示, FHBPI的玻璃化转变温度为189 ℃, 在空气中5%的热失重温度为596 ℃, 表明具有良好的热稳定性; 旋转涂膜法制备的FHBPI薄膜具有良好的成膜性; 薄膜表面粗糙度为0.54 nm; FHBPI在光通信波段有较小的吸收损耗, 适合制备低损耗的光波导器件; 用FHBPI-50为波导芯层材料, FHBPI-30为包层材料, 设计制作的热光开关响应上升时间为267.9 μs, 下降时间为254.1 μs. 相似文献

In this paper, the study on the ordering path of alkaline feldspar from some volcanic areas by X-ray powder method is presented. The published data by mathematical statistics is treated, a series of formulas and figures to determine chemical composition and degree of Al site occupancy of alkaline feldspar are reset-up, and the simulated function Y=Z~(?) with Thompson's coefficients Y, Z and κ as the indexes of ordering path is suggested. Based on the difference between ordering paths distinguished by κ of alkaline feldspar from volcanic basins, the petrological characters of volcanic basins and the petrological characters of volcanic rocks, some preliminary conclusions of the origin are also summarized. 相似文献
