项目摘要

The Mineralogical Inorganic Crystal Database (MINC) is a database used in the computer center of the University of Tokyo. It contains names, chemical formulae, chemical compositions (wt %), bibliographies, places, meteorite names, lunar sample numbers, crystal data, crystal structure data, crystal structure image data of solid earth planetary materials including meteorites and lunar minerals.EPMA data of the minerals in the lunar samples are collected with image data of analyzed points. We have been studying some database programs such as Microsoft Access. We found that it is inconvenient to handle data of variable record length. In addition, we can add image data. We examined the problems and solutions of collecting and recording the image data whose volume is much bigger than the text data.The two dimensional element distribution map by the BEI, EPMA of SEM, is widely used in research. But its volume is too large to be recorded as data in the database. The mineral distribution map makes it easier to understand these two dimensional maps. The mineral distribution map is drawn by the mineral edges and their own colors. These maps can be transferred into the vector map files of Adobe Illustrator, and we can reduce their volumes. We also examined the transfer from bit map file to vector map file, and found that Adobe Streamline is better.To transfer the microscope image, or the BEI of SEM to the mineral distribution map, we found Adobe Streamline is better. The areas, including black and white areas, are painted with the same color gradation by Adobe Photoshop. Those boundaries are traced by Streamline, and the same color areas are painted by one mineral color. Then we get a vector map file. We add chemical composition information to these image files, so our database will be more useful.

矿物学无机晶体数据库（Mineralogical Inorganic Crystal Database，MINC）是东京大学计算机中心使用的数据库。包含固体地球行星物质包括陨石和月球矿物的名称、化学式、化学成分（wt %）、参考文献、地点、陨石名称、月球样品编号、晶体数据、晶体结构数据、晶体结构图像数据，并收集了月球样品中矿物的EPMA数据和分析点的图像数据。我们一直在学习一些数据库程序，如Microsoft Access。我们发现处理可变记录长度的数据是不方便的。此外，我们还可以添加图像数据。本文研究了在采集和记录体积远大于文本数据的图像数据时遇到的问题和解决方法，利用扫描电镜（SEM）的电子探针（EPMA）、电子束电子能谱（BEI）等仪器制作的二维元素分布图在研究中得到了广泛的应用。但是它的体积太大，无法在数据库中记录为数据。矿产分布图使这些二维地图更容易理解。矿物分布图是由矿物边缘和它们自己的颜色绘制的。这些地图可以转换成AdobeIllustrator的矢量地图文件，我们可以减少其体积。在位图文件到矢量图文件的转换中，Adobe Streamline的转换效果较好，在显微镜图像或扫描电镜的BEI到矿物分布图的转换中，Adobe Streamline的转换效果较好。这些区域（包括黑色和白色区域）由Adobe Photoshop绘制为相同的颜色渐变。这些边界由流线跟踪，相同颜色的区域由一种矿物颜色绘制。然后我们得到一个矢量地图文件。我们将化学成分信息添加到这些图像文件中，因此我们的数据库将更有用。
