项目摘要

It becomes evident through out present experiments that the structure of particles produced in laboratory becomes key point to elucidate the spectra observed in space. These experiments are increasing interest for the shake of discovery of pre-solar grains such as diamond, graphite, SiC, TiC, MoC, ZrC, Al_2O_3 and Si_3N_4. Since these materials are non volatile, having polymorphism, and amorphous substance, the reading of the structure becomes difficult, which is the origin to diffuse the spectroscopy, In the present project, size, shape and defect effects on the. spectroscopy have been elucidated for some materials. If the size of the particles decreased, the directions of diffusion atom were changed (Size effect). In the growth of SiC, it becomes evident that SiC can be produced by the reaction between Si and carbon even at room temperature. In addition to proceedings .of grain formation work shops, Proceedings of Antactic meteorites, 22 papers and 2 submitted papers have been collected on these reports. Results on carbon, diamond, SiC, SiO, Al_2O_3, MgO are also contained. The next developing direction of research has been seen from the present results.
通过我们目前的实验,很明显,在实验室中产生的粒子的结构成为解释在太空中观察到的光谱的关键点。这些实验对于发现太阳前的金刚石、石墨、SiC、TiC、MoC、ZrC、Al_2O_3和Si_3N_4等颗粒具有重要意义。由于这些材料是非挥发性的,具有多晶型和无定形物质,结构的阅读变得困难,这是扩散光谱的起源。已经阐明了某些材料的光谱学。当颗粒尺寸减小时,扩散原子的方向发生变化(尺寸效应)。在SiC的生长中,很明显,即使在室温下,也可以通过Si和碳之间的反应来生产SiC。除《颗粒形成工作室会议录》、《南极陨石会议录》外,还收集了22篇论文和2篇投稿论文。还包括对碳、金刚石、SiC、SiO、Al_2O_3、MgO的分析结果。从目前的研究结果中可以看出下一步的研究方向。
