矿物晶体形态数据管理模型的研究

AN APPROACH TO THE MANAGEMENT FOR THE DATABASE OF MINERAL CRYSTAL SHAPES

根据数据库管理系统原理，在矿物晶体形态计算机绘图的基础上，建立了一种适合于矿物晶体形态数据特征并具有一般数据库功能的数据输入与管理模型。该模型可以有效地管理矿物晶体形态数据（存储、查询、索引、编辑、分类等），并且可根据其有关信息计算晶体结晶要素、面角、绘晶体图等。

According to the principle about the database system (DB), a model is established whichis suitable for the representation of data about the mineral crystal shapes and the input, output andmanagement function of the general DB. It can manage effectively the data about mineral crystalshapes (storage, inquirement, index, edition and category), compute the related information suchas crystal element and crystal face angle and draw the crystals.
