But, the characteristics of its adhered-elastic fracture in high temperature and brittle fracture in low temperature were discovered during impact load test The impact fracture mechanism of the high-energy nitroamine propellant had been put forward by studying the fracture appearances of impact fracture surface, the expansion of secondary crack and the weakness or failing of mechanical structure combined with the analysis of impact fracture properties and dynamic adhered-elastic properties and structures.

通过研究冲击断裂表界面的断口形貌、二次裂纹的发展、材料的力学结构缺陷或弱点，并结合冲击断裂性能、动态粘弹性能及结构分析，提出了硝胺发射药的冲击断裂破坏机理。

After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.

添加碳后，合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右；纯钼的断裂方式以沿晶断裂为主，添加碳后，由于合金的晶界强度得到提高，合金的断裂方式变成以穿晶断裂为主，断口上有大量的解理面，具有明显的河流状花样和解理台阶，且塑性越好的断口，撕裂岭也越多；当添加的碳含量偏高时，在晶界处产生了大颗粒的碳化物，这种大颗粒的碳化物会降低合金的塑性。

Abstract］ objective to discuss the clinical meaning of the treatment of tibial plateau fracture by mipo and operation method.methods 34 cases of tibial plateau fracture with schatzker typeⅰ～ⅴ were treated by mipo during march 2005 to june 2007,then followed-up all the cases.results using mipo to treat the tibial plateau fracture in reducing bleeding and operating time,all cases had no tresis vulnus infection and necrosis,no fracture disunion,no loosening and breaking of internal fixations,etc.the knees function regained well.conclusion treating tibial plateau fractures with mipo has little obstructe in environment of fracture healing through minimally invasive,has fortes of minimally invasive,firm of internal fixations,low rate of infection,high rate of fracture healing,can reduce the complications,fit principle of biologic fixation.

目的 讨论应用微创接骨板固定术在治疗胫骨平台骨折中的临床意义及手术方法。方法运用mipo技术治疗2005年3月～2007年6月34例schatzkerⅰ～ⅴ型胫骨平台骨折，并对其进行随访观察。结果运用mipo技术治疗胫骨平台骨折，手术时间短，术中出血量少，没有发生伤口感染坏死、骨折不愈合和内固定松动、断裂等并发症，术后患者膝关节功能恢复良好。结论 mipo在治疗胫骨平台骨折时以微创来提供尽可能少受干扰的骨折愈合环境，具有创伤小、固定确实、感染率低、骨折愈合率高等优点，减少了并发症的发生，符合生物学固定的原理。
