摘要
运用国际上最先进的Instron1342动静态高级材料试验机测试了加载速率与大理岩动态断裂韧度K1d的关系，纠正了目前存在的一些错误结论，得出了符合实际的经验公式。
The relation between loading rate and dynamic fracture toughness of marble was measured with the advanced Instron 1342 apparatus. Some erroneous conclusion were corrected and the practicable experimental equations were obtained.
