摘要：The purpose of this article is to reduce the barrier of developing a house made scanning probe microscope （SPM）. Here in this paper, we cover all the details of programming an SPM controller with labVIEW. The main controller has three major sequential portions. They are system initialization portion, scan control and image display portion and system shutdown portion. The most complicated and essential part of the main controller is the scan control and image display portion, which is achieved with various parallel tasks. These tasks are scan area and image size adjusting module, Y axis scan control module, X axis scan and image transferring module, parameters readjusting module, emergency shutdown module, etc. A NI7831R FPGA board is used to output the control signals and utilize the Z-axis real time feedback controls. The system emergency shutdown is also carried out by the FPGA module. Receiving the shutdown command from the main controller, the FPGA board will move the probe to its XYZ zero position, turn off all the high voltage control signals and also eliminate the possible oscillations in the system. Finally, how to operate the controller is also briefly introduced. That messy wires fly back and forth is the main drawback of labVIEW programming. Especially when the program is complicated, this problem becomes more serious. We use a real example to show how to achieve complex functionalities with structural programming and parallel multi task programming. The actual code showed in this paper is clear, intuitive and simple. Following the examples showed in this paper, readers are able to develop simple labVIEW programs to achieve complex functionalities.

摘要：The novel zirconium oxide, nickel oxide and zinc oxide nanoparticles supported activated carbons（Zr-AC, Ni-AC, Zn-AC） were successfully fabricated through microwave irradiation method. The synthesized nanoparticles were characterized using XRD, HR-SEM, XPS and BET. The optical properties of Zr-AC, Ni-AC and Zn-AC composites were investigated using UV–Vis diffuse reflectance spectroscopy. The photocatalytic efficiency was verified in the degradation of textile dyeing wastewater（TDW） in UV light irradiation. The chemical oxygen demand（COD） of TDW was observed at regular intervals to calculate the removal rate of COD. Zn-AC composites showed impressive photocatalytic enrichment, which can be ascribed to the enhanced absorbance in the UV light region, the effective adsorptive capacity to dye molecules, the assisted charge transfer and the inhibited recombination of electron-hole pairs. The maximum TDW degradation（82% COD removal） was achieved with Zn-AC. A possible synergy mechanism on the surface of Zn-AC was also designed. Zn-AC could be reused five times without exceptional loss of its activity.

摘要：附图 滚子链的传动布置形式 (a)推荐使用(b)容许使用 (c)不推荐使用1 滚子链的选择 滚子链传动方式的初步确定往往是通过有关图表来解决。对一种特定的使用场合,虽然有几种链可供选择,一般来说在规定的速度下能传递所需要功率的最小节距的单排链是一种最经济的选择。较小的节距的链能适应较高的速度,如因速度和空间传动尺寸所限,不能采用大节距时还可采用多排链。如果两链轮中心距大而速度是中慢速度,那么采用双节距链是一种比较好的选择。2 链的长度 链的长度只能是节距的整数倍。链传动设计中应考虑采用偶数节,因为奇数节要求有一个过渡链节。过渡链节应该尽可能避免,

摘要：评述了观测海洋的超过100年的历史。海洋观测的特别种类(如船载水文、系泊和漂流浮标)与这些测量可能带来的一些发现和动力认识一起进行了概述。到1970年代,孤立的和"探险队"观测方法演化成为覆盖大面积海洋、处理多尺度现象、使用各种仪器设备并配备模拟和分析研究团队的外场试验。洋中动力学试验(MODE)面对中尺度"涡旋"及其与更大尺度洋流的相互作用,采用了新的海洋模拟和试验设计技术,还开发了一系列观测方法。MODE之后,新仪器站网建立,用于研究控制不同区域海洋行为的过程。热带海洋全球大气项目得到热带太平洋多年时间序列,并最终预报了像ENSO这样的耦合海洋大气现象。世界海洋环流试验(WOCE)在较少漂浮和系泊设备直接速度观测区域,利用温度、盐分和其他示踪观测在全球海洋量化海洋传输。东部和西部边界层洋流吸引了复杂的观测,不同沿海区域有其独特的科学和社会意义上重要的现象,成为区域观测系统的的选择地。当前出现的很多类型仪器组成网络观测阵列的趋势在持续,为认识和预报大尺度海洋现象提供了可行之路。

摘要：The goal of the present study was to examine the relationship between flexible cognitive control and aesthetic appreciation. Participants viewed black and white artistic photographs. They used a visual scale to indicate their preferences for the photographs and rated the photographs using five semantic differential scales. Participants also performed a Stroop task, with trial-to-trial task performance analyzed to index the degree of flexible cognitive control possessed by each participant. The results showed little evidence that flexible cognitive control was a significant factor affecting impressions and preferences for photographs. The results are discussed in terms of how the degree of flexible cognitive control that a naive viewer possesses may not be sufficient in and of itself to produce a different aesthetic experience.

摘要：由于环保和效率等原因混合电动车辆(HEVS)已经具有很大的吸引力。一个典型的HEV由两个动力系统:一个是普通的动力源如一台汽油机、一台柴油机或一组燃料电池和一个电动系统(包含一台电动机和一台发电机)组成,它可能产生比普通车辆高的燃油经济性。而且,这样的车辆不需要外部充电,而在其内部存在燃料基本设施。HEV的功率分流动力系统构造的独特的HEV动力系统结构串联和并联型式的优点。但是操纵功率分流HEV动力系统要求一个完善的控制系统。设计这样的控制系统要有适当精确的HEV装置的平面模型。对于串联和并联型式的大量研究已经开发了许多动力平面模型。但一个完整的和有效的功率分流HEV动力系统的动力模型尚处于初期阶段。本文提出了在不同传动条件下可实际地和重复所有静态和瞬态现象的功率分流动力系统HEV的动力模型。首次表明了数学推导和这种平面模型和构件的表达,其次是通过计算机仿真分析、验证及性能鉴定和试验车辆在Ford公司性能道路试验实测进行比较。该模拟和实验结果的极好的吻合证实所引导的平面模型的精确性和正确性。因为该平面模型是综合用型谱方法论的系统定向子系统建立的,它很容易改变子系统的功率。开发该平面模型是用来分析和了解动力系的控制动力学,子系统和构件间的干扰以及由于工况和波动的影响的变化的系统瞬变。该平面模型也可用于车辆系统控制器的开发,能量管理战略的估价,结果的解析,编码算法的证明,及其中其他许多目的。
