查询词典 triangular matrix

Finally, by studying on using saw blades with different matrices cutting different stones, a basic compatibility rule about matrices and stones was concluded, say, when cutting a hard, high quartz and high alkalifeldspar content and strong bonded stone, a high impact strength and low wear-resistance matrix should be chosen; otherwise, when cutting a soft, low quartz or no quartz content and weak bonded stone, a high bending strength, low impact strength and high wear-resistance matrix should be chosen.

最后，通过对不同性能结合剂的锯片切割不同石材的切削寿命和磨损状态分析，得出了锯片结合剂性能与岩石性质之间的一般性匹配原则：即对于坚硬的、高石英含量的花岗岩，宜选用高强度、高冲击韧性、低耐磨性和对金刚石具有良好粘结性能的结合剂；对于低硬度、无石英或低石英含量的易切削花岗岩，宜选用高强度、高耐磨性和低冲击韧性的结合剂。
