Preparation and photochromism of nanocomposite thin film based on polyoxometalate and polyethyleneglycol

A photochromic nanocomposite based on Keggin structure phosphomolybdic acid (PMoA) well dispersed in polyethyleneglycol (PEG) was fabricated. TEM image showed that PMoA nanoparticles with narrow size distribution were finely dispersed in polymer matrix. FT-IR results showed that the Keggin geometry of polyoxometalates was still preserved inside the composites and strong coulombic interaction was built between PMoA and polymer matrix. Under UV irradiation, the film was reduced photochemically to yield a blue species, which was in accordance with a charge-transfer mechanism.     

低浓度氨氮条件下厌氧氨氧化反应器的启动研究

对低浓度氨氮(12mg/L)条件下厌氧氨氧化反应器的启动进行了试验研究,采用SBR在5个多月的时间内成功实现了厌氧氨氧化反应器的启动,并培养出了颗粒污泥。在稳定运行期间,氨氮和亚硝酸盐氮的去除率分别为94.5%和97.4%;氨氮、亚硝酸盐氮的容积负荷分别为11.4g/(m3·d)和11.1g/(m3·d)。     

抓人性化管理 构筑和谐企业

人性化管理是基于人性特征而实施管理的一种模式，其本质是尊重人的本性、满足人的需求、激励人的热情、调动人的积极性和发挥人的创造性，实现组织和组织成员的共同发展。改革开放以来，人性化管理的思想和方法逐步被轮胎企业管理者所重视，并且不断实施人性化管理。人性化管理逐渐成为轮胎企业培育核心竞争力最为重要的管理模式之一。     

Results of a User Study on 2D Hurricane Visualization

We present the results from a user study looking at the ability of observers to mentally integrate wind direction and magnitude over a vector field. The data set chosen for the study is an MM5 (PSU/NCAR Mesoscale Model) simulation of Hurricane Lili over the Gulf of Mexico as it approaches the southeastern United States. Nine observers participated in the study. This study investigates the effect of layering on the observer's ability to determine the magnitude and direction of a vector field. We found a tendency for observers to underestimate the magnitude of the vectors and a counter‐clockwise bias when determining the average direction of a vector field. We completed an additional study with two observers to try to uncover the source of the counter‐clockwise bias. These results have direct implications to atmospheric scientists, but may also be able to be applied to other fields that use 2D vector fields.     

SOC设计中的浮动压焊块电源/地线网络设计和优化

随着VLSI工艺技术的发展和芯片规模的不断增加，尤其是在SOC设计中，原有的那种供电压焊块只能位于芯片边缘的确定益的模式已经不能够满足整个电路性能的需要。在很多情况下，依靠在电源线的拓扑结构确定后的线宽优化，还是无法保证在有限的布线资源下为电路提供可靠的高性能的供电需求。由此，出现了在芯片边缘上浮动放置压焊块及在芯片的顶部放置供电压焊块阵列的方法。文中提出了一种用于SOC设计中新的基于树型结构的浮动压焊块的电源／地线网络优化算法，经过MCNC电路实例测试后得到明显的优化结果。     

岩电实验饱和度模型在探明储量中的应用

合油饱和度是评价砂岩油气层最主要的参数。确定合油饱和度的方法较多，确定储层原始合油饱和度的方法主要有直接法和间接法，直接法是指应用密闭取心或油基泥浆取心井获得的资料，通过实验室分析直接获得原始合油饱和度的方法；间接法是指应用测井曲线、毛管压力曲线、类比等资料间接获得原始含油饱和度。阿尔奇公式是测井定量解释饱和度的理论基础。在实验室条件下，通过作模拟地层条件下的岩电实验，取得地层的真电阻率，对深侧向视电阻率进行厚度校正，建立正确的饱和度解释模型，使岩电实验所建立的饱和度模型在探明储量中得到了广泛的应用。
