高职毕业生职业能力结构模型研究与标准制定

通过对人才定义的内涵分析,提出了成为人才的三个基本阶段。通常情况下,高职毕业生还不能成为人才,只能是人材。为此,在充分调研基础上,研究设计了高职毕业生(人材)职业能力的三维度四层次结构模型。设计开发了《GX/SDWZ 011-2015高职毕业生(人材)职业能力要求》标准,以此作为高职院校对毕业生的职业能力进行评价的标准。

从斯克里亚宾钢琴前奏曲中探其和声语言神秘色彩的演化进程

斯克里亚宾一生作品中的和声典型形式“神秘和弦”和特殊九和弦，这两种独特的和弦形式在他的中晚期作品中才逐步真正完满形成，本文拟其24首钢琴前奏曲作为他创作生涯的早期断面，简单剖析其独特的和声方法从初期萌芽及演化过渡的过程。

中国经济社会协调发展的经济社会学分析

经济社会协调发展是经济社会学的一个基本观点,经济社会学研究的一个重要目的和归宿点是为了促进经济社会的协调发展。深入研究分析科学发展观中的新表述、新思想、新观念、新目标、新要求,科学发展观就是一种经济社会协调和谐发展的理论,而其中所蕴涵的"一核心四维度(价值核心、内容维、空间维、时间维、方法维)"系统结构,就体现了经济社会学理论中系统观、时空观、进程观的有机统一,对经济社会发展协调发展理论进行了重大创新和发展。

Stability margin of the quadruped bionic robot with spinning gait

Spinning gait is valuable for quadruped robot,which can be used to avoid obstacles quickly for robot walking in unstructured environment. A kind of bionic flexible body is presented for quadruped robot to perform the spinning gait. The spinning gait can be achieved by coordinated movement of body laterally bending and legs swing,which can improve the mobility of robot walking in the unstructured environments. The coordinated movement relationship between the body and the leg mechanism is presented. The stability of quadruped robot with spinning gait is analyzed based on the center of gravity( COG) projection method. The effect of different body bending angle on the stability of quadruped robot with spinning gait is mainly studied. For the quadruped robot walking with spinning gait,during one spinning gait cycle,the supporting polygon and the trajectory of COG projection point under different body bending angle are calculated. Finally,the stability margin of quadruped robot with spinning gait under different body bending angle is determined,which can be used to evaluate reasonableness of spinning gait parameters.

日本音乐的寻源与泰国西北少数民族民歌

我早就认为日本的音乐之源主要有两条:其一是北方系统,日本民谣中唱的所谓“追分系统”(即自由节奏系统)的歌,即来自中国的西藏,蒙古一带。听到西藏牧民在马背上哼唱“金马鞍”这首歌时,会因为它酷似日本的“追分”而吃惊。在其发声方法、音乐风格以及四度结构的五声音阶方面都是那么相似,特别是集中力量拖长一个音的末尾并加以颤摇这种方式实在太相似了。据认为,这是北方游牧文化的源流。(北方游牧文化——江上波夫以“骑马民族说”为基础的看法)。

Tomographic TR-PIV measurement of coherent structure spatial topology utilizing an improved quadrant splitting method

In this paper,we calculated the spatial local-averaged velocity strains along the streamwise direction at four spatial scales according to the concept of spatial local-averaged velocity structure function by using the three-dimensional three-component database of time series of velocity vector field in the turbulent boundary layer measured by tomographic time-resolved particle image velocimetry.An improved quadrant splitting method,based on the spatial local-averaged velocity strains together with a new conditional sampling phase average technique,was introduced as a criterion to detect the coherent structure topology.Furthermore,we used them to detect and extract the spatial topologies of fluctuating velocity and fluctuating vorticity whose center is a strong second-quadrant event(Q2) or a fourth-quadrant event(Q4).Results illustrate that a closer similarity of the multi-scale coherent structures is present in the wall-normal direction,compared to the one in the other two directions.The relationship among such topological coherent structures and Reynolds stress bursting events,as well as the fluctuating vorticity was discussed.When other burst events are surveyed(the first-quadrant event Q1 and the third-quadrant event Q3),a fascinating bursting period circularly occurs:Q4-S-Q2-Q3-Q2-Q1-Q4-S-Q2-Q3-Q2-Q1 in the center of such topological structures along the streamwise direction.In addition,the probability of the Q2 bursting event occurrence is slightly higher than that of the Q4 event occurrence.The spatial instable singularity that almost simultaneously appears together with typical Q2 or Q4 events has been observed,which is the main character of the mutual induction mechanism and vortex auto-generation mechanism explaining how the turbulence is produced and maintained.

Growth of Sr_2CuO_(3+δ) superconductor single crystals at high pressure

We have successfully synthesized Sr 2 CuO3+δ single crystals under high pressure and high temperature for the first time. The structure analysis show that this material crystallizes into tetragonal structure isostructural La 2 CuO4 with single CuO 2 plane. The magnetic susceptibility as well as resistance measurements indicates that the bulk superconductivity with the critical transition temperature 37 K is achieved in the crystal.

A robust self-healing polyurethane elastomer: From H-bonds and stacking interactions to well-defined microphase morphology

Self-healing materials have attracted considerable attention because of their improved safety, lifetime, energy efficiency and environmental impact. Supramolecular interactions have been extensively considered in the field of self-healing materials due to their excellent reversibility and sensitive responsiveness to environmental stimuli. However,development of a polymeric material with good mechanical performance as well as self-healing capacity is very challenging. In this study, we report a robust self-healing polyurethane(PU) elastomer polypropylene glycol-2-amino-5-(2-hydroxyethyl)-6-methylpyrimidin-4-ol(PPG-mUPy) by integrating ureidopyrimidone(UPy) motifs with a PPG segment with a well-defined architecture and microphase morphology.To balance the self-healing capacity and mechanical performance, a thermal-triggered switch of H-bonding is introduced. The quadruple H-bonded UPy dimeric moieties in the backbone induce phase separation to form a hard domain as well as enable further aggregation into microcrystals by virtue of the stacking interactions, which are stable in ambient temperature. This feature endows the PU with high mechanical strength. Meanwhile, a high healing efficiency can be realized, when the reversibility of the H-bond was unlocked from the stacking at higher temperature. An optimized sample PPG1000-mUPy50%with a good balance of mechanical performance(20.62 MPa of tensile strength) and healing efficiency(93% in tensile strength) was achieved. This strategy will provide a new idea for developing robust self-healing polymers.
