关于长江重大问题的思考

长江流域横跨我国华东、华中、西南三大经济区,地理位置优越,水资源得天独厚,是我国最重要的经济区域之一。新中国成立后,党和政府高度重视长江治理开发工作,组建了流域机构,开展了流域综合利用规划,初步建立了长江防洪、灌溉、水力发电、航运、水土保持和水资源保护体系,在保护

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.
