    随着企业自身不断的发展,员工规模在不断增加,这时企业内部人力资源管理事务非常繁多,如果还是靠行政人员人工处理和安排,工作量会越来越大。比如当一个公司发展到上市以后员工人数接近一千,这时如果用传统的方式来维护员工主数据管理、文档管理、会议管理、请假统计管理及考勤汇总计算等,那是非常沉重的工作量,需要大量的人力资源,这无疑大大增加企业内部管理成本。但随着互联网信息技术的快速发展和普及,对于目前以上的这些问题可以通过开发一套内部人力资源管理系统来非常方便的解决。因此当下急需这套系统来减轻人力资源部门的工作量提高工作效率。本论文正是探讨对如何实现一个完善的企业内部人力资源管理系统进行具体设计和分析。 ...With the continuous development of enterprises themselves, the scale of the staff is increasing, the internal human resource management is very many, if we still rely on the administrative personnel to deal with and arrange, the workload will be more and more big.

    塔里木河下游地下水位对柽柳叶绿素荧光特性的影响

    选取塔里木河下游3处地下水埋深>6m的监测井位作为研究点,结合典型生态监测断面的地下水位监测数据,分析不同地下水埋深处柽柳的叶绿素荧光特性和光系统的光合活性.结果表明:随着地下水埋深加大和干旱胁迫加剧,柽柳叶片的实际光化学效率、电子传输速率和光化学猝灭等参数普遍下降;非光化学猝灭和调节性能量耗散量子产量等参数显著升高,而最大光量子产量总体处于相对适宜状态.干旱胁迫下柽柳的PSII光合活性随地下水埋深增大而下降,捕获光能的过剩程度加剧,发生光抑制的几率增大,其自身良好的抗旱性和自我调节机制,使光系统II尚未发生显著光损伤

    Catalytic Cracking and Heat Sink Capacity of Aviation Kerosene Under Supercritical Conditions

    Get PDF
    Catalytic cracking of China no. 3 aviation kerosene using a zeolite catalyst was investigated under supercritical conditions. A three-stage heating/cracking system was specially designed to be capable of heating 0.8 kg kerosene to a temperature of 1050 K and pressure of 7.0 MPa with maximum mass flow rate of 80 g/s. Sonic nozzles of different diameters were used to calibrate and monitor the mass flow rate of the cracked fuel mixture. With proper experiment arrangements, the mass flow rate per unit throat area of the cracked fuel mixture was found to well correlate with the extent of fuel conversion. The gaseous products obtained from fuel cracking under different conditions were also analyzed using gas chromatography. Composition analysis showed that the average molecular weight of the resulting gaseous products and the fuel mass conversion percentage were a strong function of the fuel temperature and were only slightly affected by the fuel pressure. The fuel conversion was also shown to depend on the fuel residence time in the reactor, as expected. Furthermore, the heat sink levels due to sensible heating and endothermic cracking were determined and compared at varying test conditions. It was found that at a fuel temperature of similar to 1050 K, the total heat sink reached similar to 3.4 MJ/kg, in which chemical heat sink accounted for similar to 1.5 MJ/kg

    室温离子液体是一类完全由阴、阳离子组成并且在室温或室温附近呈液态的物质,具有宽的电化学窗口、低的蒸汽压以及良好的电导率等传统电解质溶液不可比拟的优势,引起了电化学家的强烈兴趣。然而,相比于离子液体在电沉积、电容器、电催化等体系中的广泛应用,“电极/离子液体”界面双电层和界面电荷转移动力学的研究仍处于初始阶段:界面双电层结构模型和电势分布尚不完善,尤其是现有工作中大量使用的Au单晶电极在离子液体中的表面刻蚀和重构等行为使得界面过程变得更加复杂;而界面电荷转移动力学方面的理论模型严重缺乏,实验研究也多集中于多晶电极上,人们无法对“电极/离子液体”界面双电层结构与界面电荷转移过程建立合理的关联。因此...Ionic liquids are a class of substance, which consist entirely of ionic species and are often fluid at or around room temperature. Compared with traditional electrolyte solutions, ionic liquids have many extraordinary properties, especially the wide electrochemical window, low vapor pressure and good ionic conductivity, which make them of much interest to electrochemists. However, unlike the exten...学位:理学博士院系专业:化学化工学院_物理化学学号:2052011015369

    本文以对县级报刊在1928、1936、1941三个不同年份的分布和归属类型为线索,试图复原在此期间中国报刊基层化的走势与动因。从统计的结果来看,国民党党报在县报的空间扩展中扮演了主角。由于资源获取方式上的差异,党报与民营报刊本不存在彼此消长。但就当时中国普通县份的普遍状况而言,却更有利于被作为组织构成部分,而被自上而下嵌入的党报迅速生长。在全面抗战爆发后,由于富庶县份大多沦陷,大报发行网络的弱化,国民党党报在战区各省不仅进一步加强了在县级的空间分布优势,也在客观上充当了基层新闻流动的主脉。Following the distribution and attribution of county newspapers in 1928,1936 and 1941, this paper tries to restore the trend and motivation of Chinese newspaper at the grass-roots level. From the perspective of the results of statistics, the KMT party newspaper played a leading role in the space expansion of the county newspaper. Due to differences of resource access, party newspapers and private newspapers did not affect each other. In terms of the general situation of Chinese general county, it was more conducive to the organization as a component embedded in a top-down party newspaper to get a rapid growth.Alter the outbreak of the Anti-Japanese War, the Kuomintang party newspaper not only strengthened the spatial distribution advantage further at the county level in the theater provinces, but also objectively was acted as the main vein of grass- roots news flow.本文系厦门大学2017年度校长基金项目:从嵌入到遍在:对报刊在近代中国的空间扩散的动力学探究(编号20720171044)项目成果
