基于Carson理论建立简单链型悬挂接触网电流分布模型;结合铁路现场的实际供流数据,分别对受流点位于跨中和跨端2种情况下的接触网各导线实际受流情况进行仿真计算;基于电致塑性效应理论,采用对断裂吊弦进行SEM形貌分析、成分分析及对新旧吊弦的金相组织进行对比观察等试验手段,研究吊弦断裂过程中电气因素的作用机理。结果表明:在满足机车正常运行的条件下,吊弦在受电弓滑过其正下方瞬间处于电流过载状态,随后迅速衰减;断裂吊弦的表面和断口处均存在过载引起的氧化腐蚀现象;吊弦在电致塑性效应影响下会发生金相组织再结晶、材料变形抗力降低现象;电流过载引起的表面缺陷及电致塑性效应引起的材料变形抗力降低是加速吊弦疲劳断裂的重要原因。

North China Mountain Walnut (NCMW) is one of the ancestors of extant cultivated species, and a valuable gene resource for resistance breeding of walnut in China. Inter-Simple Sequence Repeat (ISSR) primers were designed to evaluate the level and pattern of genetic diversity in eight populations of NCMW. Nine ISSR primers yielded 91 amplification products with different sizes, of which 84 (92.31%) were polymorphic. A high species-level genetic diversity was detected with Nei’s (H = 0.2592) and Shannon’s diversity (I = 0.4003). In contrast, the population-level genetic diversity was relatively lower (PPB = 43.27%, H = 0.1347, I = 0.1862). Coefficient of populations differentiation (GST) was 0.5066, indicating that inter-population and intra-population variation contributed 50.66% and 49.34% respectively to the total genetic variability. This relative level of variation was further supported by AMOVA analysis. Limited gene flow (Nm = 0.5133.), habitat fragmentation and geographical isolation might be responsible for the population structure of NCMW. UPGMA cluster analysis classified the eight populations into three groups which showed no significant relationship between the genetic similarity coefficient and geographic origin but showed remarkable association with morpho-physiological characters, particularly nut traits. The results of the study provide species-level and population-level genetic profiles for further exploitation and conservation of genetic diversity of NCMW.

In many real-time control systems, data flow is the base structure of software model. The QoC (Quality of Control) of some systems not only relate to whether the temporal constraints of real-time tasks can be met, but also relate to whether the data flow is non-suspending. While the data flow is suspending, both the control precision and running speed would degrade. For preventing the data flow suspending, we introduce a real-time scheduling algorithm that considers the risk of data flow suspending. We also present an implementation framework for real-time scheduling algorithm based on RTAI. It can simplify the implementation and verification of real-time scheduling algorithm. The results of verification manifest the DFO-RSA algorithm can prevent the data flow suspending effectively while guarantee the temporal constraints of critical tasks.
