中子活化技术在层序地层学中的应用

在计算机硬件、软件技术高速发展的基础上，笔者用ＱＢＡＳＩＣ语言成功地开发出一种在普通４８６以上微机上运行的，高效、准确、直观地显示各种分子及晶体结构的高性能的实体造型系统，可以较好地满足材料科学及矿物学等各领域的迫切需要。输入数据简单，界面友好，操作简便，功能十分丰富。可以自由地选择颜色、光照、材质和结构表达方式等多种参数。应用此系统已制作出上千幅精美的晶体结构的高分辨率真彩色实体图片，有非常显著的效果和巨大的应用推广价值。

BRIDGE HIGH PERFORMANCE MOLECULAR AND CRYSTAL STRUCTURE 3D MODELLING SYSTEM

Based on a quickly developped technology of computer hardware and software, a powerful multifunctional 3D drawing system has been built up successfully, which is capable of doing a high efficient, accurate, intuitional display of molecular and crystal structures by using only a low cost personal computer system (486/586). This system could well satisfy the urgent needs in areas for material scientists and mineralogists .It is easy to use in operation. Interface is used friendly, and inputting data is very simple. All parameters for colors, lighting, materials and express mode can be selected freely. Applying this system, thousands of beautiful high resolution colorful 3D structure pictures have been constructed already. It has been proved that the system can be widely accepted and is of benefit to the users of material scientists.
