本文主要介绍本科研组研制成功的DFZY型金刚石单晶及复合片冲击破碎能测定仪及利用该测定仪对单晶金刚石和复合片所进行的试验研究，从而得出了：金刚石动强度和静强度的关系；金刚石动强度随其粒度的变化关系；受力状态对金刚石抗动载性能的影响。
In this paper, DFZY-type diamond single crystal and composite impact crusher capable of measuring successfully developed by the research group and the experimental research on the single crystal diamond and composite sheet using the analyzer have been made. The results show that the dynamic strength and static The relationship between the dynamic strength of diamond and its particle size; the influence of stress state on the anti-dynamic performance of diamond.
