1·This paper mainly researched into the gold tailing which could be used to make minicrystal glass granite.

对利用黄金尾砂制造微晶玻璃花岗石进行了研究。

2·Glass-ceramics material which is composed of uniform distribution glass phase and minicrystal phase, can be prepared by the parent glass via controlling the behavior of crystallization.

微晶玻璃是由基础玻璃经控制晶化行为而制成的微晶体和玻璃相均匀分布的一种新型无机非金属材料。

3·Through experiments, the improvement can reduce the content of minicrystal to 31.8 percent, compared with an original protective plate without a through hole for the cooled air to circulate.

通过试验，相对于原先没有用于冷却气体流通用的通孔的护板，该改进可以把微晶含量减少到31.8%。
