1颈内动脉外翻内膜剥脱术治疗颈动脉狭窄疗效分析显示文摘目的探讨颈内动脉外翻内膜剥脱术治疗颈动脉狭窄的疗效.方法对127例颈动脉粥样硬化性狭窄患者行颈内动脉外翻内膜剥脱术,其中有症状者78例,无症状者49例.术后随访5~16个月,回顾性分析其疗效,评价此术式的优点.结果全组无手术死亡病例.术后患者均复查颈部和脑实质DSA,显示患侧颈动脉形态正常,颈内动脉血管迂曲消失,无1例狭窄.126例患者脑部供血有明显改善,其患侧颈内动脉、皮质下血管显影时间较术前提前0.40~0.90 s,颅内血管血流经过时间缩短0.50~0.80 s;出现脑梗死1例,遗留永久性神经功能缺损,有效率为99.2%,并发症发生率为2.4%.结论颈内动脉外翻内膜剥脱术是一种有效、安全治疗颈动脉粥样硬化性狭窄的手术方式.张佳栋 温向阳 D Maza 2005中国脑血管病杂志2005,2,11:3
2Operation power consumption and verification tests of a trenching device for orchards in Xinjiang based on discrete element显示文摘According to the agronomic requirements of orchard planting pattern and fertilization in Xinjiang,the soil particle models and a soil-trenching device interaction model were established by using discrete element simulation software in order to find out the law of influence of structure parameters and working parameters on the operation power consumption of a segmented cutting trenching device;moreover,its cutting process was simulated according to the response surface test design.According to the results of research on the influence of forward speed,cutter disk speed and cutter disk combination on the operation power consumption of the segmented cutting trenching device,the law of their influence on the operation power consumption in descending order is forward speed,cutter disk combination,cutter disk speed.According to the response surface test result,the following influential factor parameter combination has been obtained:forward speed 815 m/h,cutter disk speed 112 r/min,cutter disk combination A(cut angle 150°,bent angle 60°and working width 133 mm),cutter disk combination B(cut angle 180°,bent angle 90°and working width 166 mm),and trenching operation power consumption-optimization results were verified through field tests.According to the verification,the results showed a high accuracy of the simulation,with a relative error mean of 3.18%between the theoretical value and the field test value.This study can provide a reference for the energy-saving design of orchard trenching devices.Chen Ma Jiangtao Qi Za Kan Shaojie Chen Hewei Meng 2021International Journal of Agricultural and Biological Engineering2021,14,1:3

18Design and parameter optimization of spiral-dragon type straw chopping test rig显示文摘In order to address the problems of large chop length,high energy consumption and poor chopping effect that were associated with a horizontal total mixed rations(TMR)mixer,a straw chopping device was designed;further,its structure and working principle were analyzed.In this study,wheat straw was chosen as the test object.The number of processing times,number of fixed blades,cutting speed,number of tooth plates and the inclined angle of the box were considered as the test factors.The standard straw length rate and average power were used as evaluation indices for conducting the orthogonal rotation combination experiment with five factors and five levels of quadratic regression.The experimental results denoted that the order of influencing factors on the standard straw length rate can be given as follows:the number of processing times,number of fixed blades,cutting speed,number of tooth plates and inclined angle of the box.The order of the influence of each factor on the average power can be given as follows:the cutting speed,number of fixed blades and number of tooth plates.Further,the optimum structural and working parameters of the device can be determined as follows:linear cutting speed of 17-20 m/min,box inclined angle of 70°-80°,20-23 fixed blades,5-6 processing times and 4-7 tooth plates.Under such a circumstance,the standard straw length rate reached up to 70.5%-77.4%and the average power was low at 5.8-7 kW.The results can be used as reference for designing a chopping device for a TMR mixer.Pengbo Ma Liqiao Li Baoqin Wen Yunheng Xue Za Kan Jingbin Li 2020International Journal of Agricultural and Biological Engineering2020,13,1:1
