“一带一路”视角下东南亚职业型人才培养模式分析

在"一带一路"倡议推动以来,中国与东南亚各国在贸易及建设上有着更紧密的合作,在开展合作的过程中对于双方在各行各业的人才有着莫大的需求。由于国情不同,加上重大项目所涉略的领域过广,不论是中国或是东南亚国家都出现人才短缺的问题,所以当务之急是培养一批适用于双方的人才。此文梳理了东南亚各国与中国在各方面的关系,找出东南亚各国在人才培养方面所存在的问题,借鉴德国双元制教育模式来对东南亚职业型人才进行有针对性的培养

多弧离子镀制备TiSiN涂层的结构及其摩擦学行为

为了研究Si含量对TiSiN涂层性能的影响,采用多弧离子镀技术在Ti6Al4V表面制备了不同Si含量(质量分数)的TiSiN涂层。利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、电子能谱仪(EDS)、X射线光电子能谱仪(XPS)纳米压痕仪、摩擦磨损试验机表征其表面形貌、成分,力学性能及摩擦学性能。结果表明:随着靶材中Si含量的增加,涂层硬度从35GPa增加到42GPa。在TiSiN涂层中Si元素主要以Si3N4非晶态存在,形成了非晶Si3N4包裹TiN纳米晶结构。当靶材中Si含量为8%时,涂层在海水中的磨损率约为2.1×10-6 mm3/(N·m),此时涂层的摩擦性能最好

钛合金表面渗氮层与TiAlN耦合涂层的结构及性能

研究了在钛合金表面渗氮-离子镀TiAlN膜复合处理与单一离子镀TiAlN膜处理工艺对钛合金力学性能、海水环境下的摩擦学的影响。采用SEM S4800、XRD、XPS、纳米压痕仪,观察了薄膜的表面及截面形貌,分析了渗氮后的钛合金表面、单涂层及复合涂层的相组成变化,化学成分和元素价态,测试了两种样品硬度随深度的变化。结果表明,复合涂层中择优取向(200)晶面明显,复合涂层渗氮后基底硬度增加,薄膜硬度下降速度慢,有利于提高涂层的耐磨性,且在海水润滑作用下,短时间摩擦过程中复合涂层的磨损量最小

Characterization of Coenzyme Q and Preliminary Investigation on Its Effect on Life-span in Drosophila melanogaster

辅酶Q是存在于线粒体内膜上的脂溶性电子传递体,它是呼吸链的重要组成部分.辅酶Q在不同生物体内其侧链异戊二烯单位的数目不同,目前对黑腹果蝇(drOSOPHIlA MElAnOgASTEr)中辅酶Q的存在形式和含量还不清楚.利用高效液相色谱法分析鉴定了模式生物黑腹果蝇中辅酶Q的种类及含量.实验结果表明:黑腹果蝇中辅酶Q9与Q10并存,辅酶Q9的含量约为Q10的2.5倍.辅酶Q含量具性别差异,其中辅酶Q9在雌性黑腹果蝇中含量较雄性约高30%,而辅酶Q10在雌性果蝇中则比雄性果蝇高约33%;辅酶Q9与Q10含量在辅酶Q合成酶COQ2的突变体中明显降低并且COQ2突变体的寿命较野生型略短.这些实验结果将为利用黑腹果蝇模型研究辅酶Q的功能提供重要基础.Coenzyme Q is an essential component of the mitochondrial respiratory chain as a lipid-soluble electron transporter located in the inner membrane of mitochondria.The number of isoprenoid subunits in the coenzyme Q side chain varies in different species.The content of coenzyme Q in Drosophila has not been reported yet.In the present report,we analyzed the content of coenzyme Q in adult Drosophila by HPLC.We provided evidence that Drosophila contains both CoQ9 and CoQ10.The amount of CoQ9 is about 2.5 folds than that of CoQ10.We further showed the content of CoQ9 and CoQ10 in females are respectively about 30%,33% higher than that in males.In addition,both concentrations of CoQ9 and CoQ10 are significantly reduced in the mutant of CoQ synthase gene coq2 which appeared with shortened life-span.These results provided a good basis to further investigate in vivo biological functions of CoQ in Drosophila.国际科技合作项目(2009DFA32760
