An update high temperature superconducting Maglev measurement system (SCML-02) was successfully developed. The includes liquid nitrogen vessel, cylinder permanent magnet (PM) or PM guideway (PMG), data collection and processing, mechanical drive autocontrol. vessel with superconductors (HTSCs) can be placed above under the PM. This has other characteristics: precision, instant at movement of measured HTSCs specimen, synchronous levitation guidance, in three dimensions one time, relaxation...
The first man-loading high-temperature superconducting (HTS) Maglev test vehicle in the world was successfully developed on Dec. 31, 2000 Applied Superconductivity Laboratory, Southwest Jiaotong University, China. Heretofore over 24 500 passengers took vehicle, and it has been operating back forth for about 400 km. HTS provides inherent stability both vertical lateral direction, so no control system is needed. only used linear motor driving devices. melt-textured YBaCuO bulk superconductors...
In order to design high temperature superconducting (HTS) maglev launch system, three NdFeB permanent magnetic guideways (PMGs) are investigated and compared for the better levitation forces guidance forces. The laboratory-scale HTS system was designed developed successfully in Applied Superconductivity Laboratory (ASCLab), Southwest Jiaotong University, China. cooling process of melt-textured YBaCuO bulk superconductors is made a big low tube, which connected with PMG. method merit...
Since the first successful running of people-carrying high temperature superconducting (HTS) Maglev test vehicle on 31 December 2000, about 27 000 people have taken it, and accumulated distance is 400 km. The levitation force onboard HTS equipment measured periodically, new experimental results 5 March 2003 show that performance almost same as two years ago. Experimental indicate long-term stability good. This further proves feasibility for practical transportation. It worth mentioning all...
The dynamic measurement of high temperature superconducting (HTS) magnetic levitation (Maglev) vehicle is a very important and difficult problem. In order to investigate the characteristics behavior HTS Maglev, an Maglev system (SCML-03) was successfully developed in Applied Superconductivity Laboratory (ASCLab) Southwest Jiaotong University, P. R. China. mainly constituted by circular permanent magnet guideway (PMG), liquid nitrogen vessel, data acquisition processing, mechanical drive,...
Because of the disadvantages existing permanent magnetic guideway (PMG) such as low efficiency, a Halbach PMG is proposed to improve levitation performance high-temperature superconducting (HTS) (maglev) vehicle. Magnetic induction calculated by an analytical method. The screening current density distribution in superconductor solved with flux flow-creep model finite-element method, and then force between HTS bulk Lorentz formula. According characteristic maglev vehicle, optimality criterion...
When the velocity of normal ground traffic transportation is higher than 350 km/h speed limit, not only running noise vehicle higher, but also 90% driving power dissipated in aerodynamic resistance. The high may be realized when a temperature superconducting (HTS) Maglev runs low-pressure tube or evacuated transport (ETT). Its over 3000 km/h. As new system HTS presented after experiment results are discussed this paper.
The design consideration of the superhigh speed HTS Maglev vehicle system 1000 m test line is presented on basis experiment results in years before last. gross weight NdFeB guideway 6750 kg. low temperature rectangle-shape liquid nitrogen vessel board has high mechanical strength at 77 K temperature. 5 mm bottom thickness and 12 hours continuous working time. There are two seats vehicle. total load 500 kg including 150 passengers weight. body quasiellipsoidal shape, outside outline size with...
目的 探讨股骨粗隆重建加翻修长柄人工股骨头置换治疗高龄不稳定型股骨粗隆间骨折的临床疗效。 方法 回顾性分析2014年3月—2016年9月江西省进贤县人民医院骨科手术治疗的59例高龄股骨粗隆间粉碎性骨折患者临床资料，其中男28例、女31例，年龄78～95岁。均采用2枚克氏针加钢丝环扎技术重建股骨大粗隆结构，翻修加长柄人工股骨头置换手术。术后随访观察关节假体和大粗隆愈合等情况，采用Harris髋关节评分对疗效进行评定。 结果 59例病例均顺利完成手术，其中1例打入假体过程中出现股骨近端劈裂骨折，予环形钢丝捆扎，长柄假体置入。手术时间80～120 min，术中失血量200～400 mL，术中、术后输血300～600 mL，术后下床时间3～6 d，住院时间12～18...
Software-defined networking (SDN) has the ability to flexibly configure network and is widely used in various scenarios. In SDN, different applications require controller deploy corresponding flow entries maintain effectiveness of network. However, matching field range covered by may overlap, when actions specified these overlapping are inconsistent, conflicts occur. Such cause match wrong entry, thereby affecting correct expression application functions. The scheme we proposed this paper...
