The morphological features , the inclusion features , the ultraviolet - visible absorption spectrum , infrared spectrum and the cathodoluminescence features of the flux - grown synthetic spinel provide reliable evidence for identification 助熔剂法合成尖晶石的晶体形貌特征和包裹体特征以及紫外可见吸收光谱、红外光谱和阴极发光特征为其鉴定提供了可靠的依据。

Among the discrimination criterion controlling the alteration of carbonate , neither cathodoluminescence of the carbonate minerals nor t he content of sr can act solely as discrimination criterion for controlling the alteration of marine carbonate 在碳酸盐的阴极发光性、 sr含量和mn sr比值三个判断成岩蚀变性的标准中，阴极发光性和sr含量不能单独作为判断标准来检测海相碳酸盐矿物的成岩蚀变性。

Various types of techniques have been applied to study the main principle problem . these techniques involve petrography , x - ray diffraction ( xrd ) , scanning electron microscope ( sem ) , carbon isotope , cathodoluminescence ( cl ) , fluid inclusion , and epoxy - resin casts 论文中所用的分析原理与技术方法包括：层序地层学分析、 x -衍射、扫描电镜、稳定同位素、阴极发光、流体包裹体与染色铸体薄片等。

The mn / sr value considers the mn content for control factors of cathodoluminescence and the relative content of the marine versus terrigenous elements . so the mn / sr ratio is the relatively comprehensive discrimination criterion for controlling the alteration of marine carbonate Mn sr比值在考虑了控制碳酸盐阴极发光性的mn含量的同时，兼顾了海相和陆相元素的相对含量，因而是一种较全面的成岩蚀变性判断标准。

The conventional methods of the gemmology and the modern instruments of electronic probe , ultraviolet - visible spectrophotometer , fourier transform infrared spectrometer , cathodoluminescence spectrometer are used to research and analyse the flux - grown synthetic spinel and compare them with the natural spinels 摘要采用常规的宝石学研究方法以及电子探针、紫外可见分光光度计、傅里叶变换红外光谱仪和宝石阴极发光光谱仪等现代测试仪器，对助熔剂法合成尖晶石的宝石学特征进行了全面分析，并与天然尖晶石进行了对比。

Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence , observation of thin sections , and analysis of sr and mn . the mn / sr value of all samples presented in this paper are less than 2 , and the cathodoluminescence is dull , however , the samples from the cambrian underwent diagenetic alteration to a certain degree , and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete . the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world , supporting the notion of global consistency of strontium isotope composition of marine carbonates 根据锯同位素地层学的基本原理，利用已有的锯同位素演化曲线，笔者确定重庆秀山寒武系剖面寒武系底界、下一中寒武统界线和中一上寒武统界线都应适当下移；另外尝试确定了重庆秀山寒武纪剖面一些关键点的年龄，累积厚度1380m处的年龄为503 ? 509ma ，累积厚度1900m处的年龄约为500ma ，这对秀山寒武系剖面下、中寒武统和中、上寒武统界线的确定具有参考价值。

Based on the variation of light / heavy mineral components of sedimentary rocks , the typomorphic characteristics of various debris , the cathodoluminescence color of quartzes , the direction of paleocurrent and the extension of sedimentary facies , two source direction of the studied area in carboniferous and permian can be recognized , one is in bayanwusu , wulan ' ge ' er and hetaoyinshan area north of hangjinqi in the north margin of ordos , another is alashan area in the northwest margin of ordos 在深入研究本区沉积岩轻、重矿物组分的变化、各种岩屑的标型特征、石英阴极发光颜色、古水流方向及沉积相带展布等基础上，认为研究区石炭?二叠纪的物源方向主要有两个，分别为：北缘杭锦旗以北的巴彦乌苏、乌兰格尔及河套阴山地区；以及研究区西北缘的阿拉善地区。

Since the carrier mobility in organic materials is very low , no collision excitation is possible . the short wavelength peak is due to direct bombardment by electrons from sic > 2 . we name this luminescence as cathodoluminescence - like ( cl - like ) emission or solid state cathode luminescence because the energized electrons are accelerated in solid instead of in vacuum 这样在有机层中的电子数是nl n计n汁n ，空穴数是p n （ n是类阴极射线激发出的电子，也是类阴极射线激发出的空穴儿这两类载流子的复合将比单纯有机发光的复合nip增加了（ n计n叶n ）叮（ l n计n叶n ） n 。

The cathodoluminescence ( cl ) analysis shows the quartz reflects an abundance of brown color , blue - purple , dark blue , dull color , and no cl color for quartz overgrowth , while feldspar shows light blue , yellow - green , yellow - brown , green and brown cl colors . the calcite reflects bright orange - yellow for non - ferroan calcite and dull orange - brown cl colors for ferroan calcite 阴极发光分析证实，砂岩中石英颗粒阴极发光颜色较深，主要位棕色、蓝紫色、深蓝色，石英加大变不发光；长石颗粒阴极发光颜色主要位浅蓝色、黄绿色、绿色、棕黄色等；无铁方解石阴极发光颜色为鲜艳桔黄色，铁方解石阴极发光颜色为暗桔黄色。
