Therefore, we changed the classification of Azema and applied it to a series of patients who had undergone open surgery of the femoral arterial bifurcation. This evaluation made it possible to have an idea of the distribution of atheromatous lesions in this region and to compare the efficiency of this modified classification of Azéma with others used in the literature. This modified classification of Azema is relevant and constitutes a decision-making tool for the endovascular therapeutic indications of femoral arterial bifurcation.展开更多
本文采用数字式粘度仪对不同温度和促进剂含量下添加氢氧化铝(ATH)的不饱和聚酯树脂(UPR)的粘度进行测试,然后以获取的实验数据作为参数,对复合材料部件模型用RTM(Resin transfer molding)和VARTM(Vacuum assisted resin transfer moldi...本文采用数字式粘度仪对不同温度和促进剂含量下添加氢氧化铝(ATH)的不饱和聚酯树脂(UPR)的粘度进行测试,然后以获取的实验数据作为参数,对复合材料部件模型用RTM(Resin transfer molding)和VARTM(Vacuum assisted resin transfer molding)两种工艺进行模拟仿真。仿真结果表明,在相同的参数条件和灌注方案下,VARTM工艺的填充时间小于等于RTM工艺的填充时间。当注口大于出口时,VARTM和RTM的填充时间基本相同;当注口小于出口时,VARTM工艺的填充时间要少于RTM工艺的填充时间。展开更多
