摘　　要：本文采用ＳＨＰＢ技术和反射式动焦散线法测定了不同配方水泥石材料的动态力学性能和断裂韧性，对增强水泥石抗冲击能的有效途径进行了实验探索，给出了两种实验方法所得结果的分析对比。The dynamic properties and fracture toughness of various cement composition samples were determined by using SHPB pressing bar technique and reflective motive focus astigmatism.The effective ways of improving the impactresistance properties of cement were studied.The analysis and comparison of the results from the two tests are given in this paper.
