The flathead oak borer Coroebus undatus E （Coleoptera： Buprestidae） is one of the primary pests of cork oak Quercus suber L. in the Mediterranean region causing great economic losses to the cork industry. Very little is known about its biology and behavior and, so far, no control measures have been established. We present the results of a pilot study aimed to develop an efficient trapping method for monitoring this harmful pest. In a 3-year field study, purple-colored prism traps baited with a mixture of green leaf volatiles （GLVs） from the host have been shown the most effective combination to catch C. undatus adults （solely females） compared to other trap and lure types tested. Wavelength and reflectance measurements revealed that purple traps exhibit reflectance peak values similar to those found in the abdominal and elytral cuticle of both sexes, suggesting the involvement of visual cues for mate location in this species. The data presented are the first to demonstrate captures of adults of the genus Coroebus by an attractant-based trapping method.

A three-phase to single-phase modular multilevel converter based advanced co-phase traction power supply(MMC-ACTPS) system is an effective structure to address the concerns of phase splitting and poor power quality of the conventional electrified railway. Due to the large number of MMCACTPS system modules, I/O resources and computing speed have high requirements on processors. Moreover, the module capacitor balance is challenging because the sorting time is too long when the traditional sorting algorithm for voltage balance is used. To solve the above issues, a digital implementation scheme of flexible power control strategy for three-phase to single-phase MMC-ACTPS system based on field programmable gate array(FPGA), which has sufficient I/O resources, has been proposed. Due to the parallel execution characteristics of the FPGA, the execution time of the controller and the modulator can be greatly reduced compared with a digital signal processor(DSP) + FPGA or DSpace. In addition, an improved sorting algorithm is proposed to reduce the sorting time and the implementation steps are analyzed. Finally, simulation and experimental results are presented to demonstrate the effectiveness and correctness of the proposed control strategy.

为实现微网系统从孤岛运行模式到并网运行模式的平滑过渡,微网与主电网的同步是首要考虑的问题。提出了一种新型基于锁相环原理的主动同步控制策略,该方法通过主动调节微网母线电压的频率、相角和幅值跟踪主电网电压,从而减小并网时刻的电压偏差,达到孤岛模式向并网模式的平滑过渡。同时,采用电压矢量叉积作为鉴相器,微网频率和相角可同时快速有效地跟踪电网频率和相角。并且该方案不需传递相位等时域信号,仅需依赖于低带宽的通信,原理简单、易于实施。最后,实时硬件在环仿真与实验结果表明,该控制方案可实现微网快速平滑并网。

采用冷喷涂法在铝(Al)基体上沉积单颗粒铜(Cu),利用聚焦离子束/电子束(FIB/SEM)系统精确定位并原位制备了完整单个颗粒Cu沉积在Al基体上的透射样品,分析其显微结构及形成原因。实验结果表明,撞击过程中温度与应力分布不均匀,导致沉积Cu颗粒不均匀形变。Cu/Al界面受影响较大:颗粒动能转化为形变能和热能,打破了界面处氧化膜,使界面附近温度迅速升高,发生动态再结晶,生成金属间化合物Cu_9Al_4;Cu颗粒内距界面越远的区域,受温度和应力的影响越小,其变形主要是通过晶体内位错增殖和移动;沉积颗粒顶部,远离Cu/Al界面,几乎不受应力和温度影响,保持原始显微结构。

研究了基体材料的力学性能对冷喷涂316L不锈钢单颗粒沉积行为的影响.结果表明,除硬度之外,弹性模量和Poisson比也会影响颗粒的沉积行为.这是由于基体性质对颗粒/基体的能量分配和结合机制造成了影响.其中,沉积颗粒的变形行为与颗粒吸收的能量有关,而沉积效率与基体吸收的能量及结合机制有关.根据沉积颗粒的变形行为,将基体分为2类:颗粒几乎不变形,此时基体的硬度和弹性模量皆低于颗粒材料,颗粒与基体的结合主要是机械咬合,推导出可用于推断相同颗粒在基体上沉积趋势的参数E_(para),并以AZ91镁合金为基体进行验证;颗粒发生强烈变形,此时基体的硬度或弹性模量高于颗粒材料,结合机制更为复杂,此时增加颗粒/基体新鲜表面接触面积有利于提高沉积效率.
