The existing situation and discussion on perfecting mechanism of integrated emergency management work in ShaoXing
近年来,在经济社会转型的关键期,我国城市公共危机事件频发,并且呈现出频率高、范围广、传播快、损失大的复合性特征。这一方面给广大群众的生命财产、经济社会的进步带来重大损失;另一方面也一定程度影响到了地方政治、经济、社会的和谐稳定、经济的发展和社会的和谐。国内广西南宁于2002年首创城市应急联系中心后,上海、深圳等先进城市也纷纷建立了较高水平的城市应急联动体系。但总体来看,这些先进城市在发挥实质性效益的专家决策和实行全民参与制的应急联动管理建设上仍然距离西方国家的纽约、伦敦和东京等发达城市有着一定的差距,在相关应急处理的法律法规体系建构上,也还有许多工作要做。绍兴现行的社会应急联动体系也存在这些普...In recent years,in the critical period of economic and social transformation, the urban public crisis happens frequently, which presents some compound characteristics of high frequency, wide range, fast spread, large loss. On the one hand, it has caused a large loss to the people's life and property as well as the development of the social economy. On the other hand, it has affected the local poli...学位:公共管理硕士院系专业:公共事务学院_公共管理硕士学号:1392011115049

Effect of Chloride Ion on Electrocrystallization of Copper on Glass Carbon Electrode
采用线性扫描伏安法和计时安培法研究了硫酸铜溶液中铜在玻碳电极上电结晶的初期行为 .在含与不含氯离子的 0 0 5mol·L-1CuSO4 0 5mol·L-1H2 SO4电解液中 ,循环伏安实验结果表明铜在玻碳基体上的沉积没有经过UPD过程 ;氯离子明显使Cu的沉积和氧化峰变得尖锐 ,促进Cu的沉积速度 .计时安培实验结果表明 ,Cu的电结晶按瞬时成核和三维生长方式进行 .氯离子不改变Cu的电结晶机理 ,但在I~t曲线中 ,导致电流达最大 (Im)所需的时间tm 减小、晶核数密度和生长速度增大 ,从而明显改变Cu沉积层的质量 .当Cl-浓度在 10~ 2 0mg·L-1范围内 ,成核的晶核数密度达较大 ,即氯离子的最适宜添加量 .The initial stage of copper electrodeposition and the influence of chloride ions on the nucleation and growth of copper on glass carbon from acid sulphate solution were studied by using the cyclic voltammetry and the chronoamperometry method. Instantaneous nucleation with three dimensional growth is found for the solutions either with or without chloride. Obviously, chloride ions increase the nucleation rate and the nuclear number density of nuclei at the surface. Since the deposits are smooth, bright at high nuclear number densities, it can be concluded that chloride ions effectively promote the smooth and brightness of surface. The higher nuclear number densities are obtained at 10~20 mg·L -1 of chloride ions. Maintaining the optimum level chloride ion concentration is beneficial to electrodeposits.国家自然科学基金 (No .2 0 0 73 0 3 7);; 优秀国家重点实验室基金 (No .2 0 0 2 3 0 0 1)资助项
Current Efficiency and Deposit Microhardness of Nickel-Tungsten Alloy Electrodeposition
通过调节镀液中不同的 nI/ W 比例、温度和沉积电流密度,研究在焦磷酸盐体系中镍钨合金电沉积的电流效率、沉积层组成和显微硬度。实验结果表明:合金共沉积的电流效率不高。为了尽量提高合金的沉积电流效率,主要途径宜增大镀液中硫酸镍和钨酸钠的浓度;提高合金沉积电流密度,降低镀液中[ nI]/[ W] 比例,则镀层中的钨含量增大;合金沉积层的显微硬度随镀层中的 W 含量提高而增大。Current efficiency, deposit composition and microhardness of nickel-tungsten alloy electrodeposition in pyrophosphorus bath were studied by adjusting Ni/W ratio in plating solution, temperature and deposition current density.The results showed that the current efficiency of the alloy codeposition was not high.For the purpose to raise current efficiency as far as possible the suitable solution was to increase the concentration of nickel sulfate and sodium tungstate in the bath, Tungsten content in the alloy deposit can be increased by raising electrodeposition current density and decreasing [Ni]/[W] ratio in the plating solution.The microhardness of the alloy deposit increases with the raise of tungsten content in the deposit.国家自然科学基
苯硫酚对固氮酶催化活性的影响
研究了苯硫酚对棕色固氮菌固氮酶催化底物还原活性的影响。结果表明:当反应体系中固氮酶钼铁蛋白与苯硫酚的摩尔比为1:4时,固氮酶的乙炔还原活性比对照组下降了62.3%,下降的幅度随着苯硫酚浓度的升高而增大;但在乙炔存在的情况下,固氮酶的放H_2活性随着苯硫酚的浓度的升高而升高。在氩气氛下,苯硫酚浓度的升高对固氮酶放H_2活性的影响不明显。这一现象有可能是由于苯硫酚取代与铁钼辅基的Fe_1原子连接的半胱氨酸的巯基而引起的
