查询词典 ratio

Top sintering material preheats for a short time、sinter at lower temperature、cools too fast and has low crystallinity, especially, network SFCA offorms difficultly in the top layer, that results in high ratio of pore, so the strength of top sinter is low. when thickness of sintering material is increased, the ratio of top sinter will be decreased, in its entirety, the strength of sinter will rise.

5烧结矿破碎属脆性断裂，一般在单轴压缩应力下受剪切产生，本文基于低氟烧结矿物质组成，导出了基体抗压强度与烧结矿物质组成的关系式，由此得出，基体抗压强度受磁铁矿影响不大，而受铁酸钙影响较为显著。
