| 1 | 多因素影响下的气候变化与河流水质显示文摘河流水质受到许多气候因子的影响,诸如气温、降水以及极端事件等。气候变化导致的水质恶化会产生一系列严重后果。以中欧地区为例,简要阐明了气候和非气候因素在影响河流水质方面的相互作用。最后,对与气候变化相关的水质变化趋势进行了分析,并指出了气候变化情景下水质模拟的要求和约束条件。 | Z.W.昆兹威克斯 梁静静 柯学莎 | 2011 | 水利水电快报2011,32,11: | 10 |
| 2 | 非工程措施防洪与可持续发展显示文摘可持续发展可定义为不降低生活质量。结合可持续发展研究防洪问题,一方面,洪水破坏人类遗产和危害可持续发展,另一方面,按照可持续发展的通常解释,人们不应选择那些可能被后人视为不恰当防洪方案的防洪政策。有些大型防洪工程通常就是这样审查的。非工程措施比较符合可持续发展的要求,更为可逆,能被人们普遍接受,不破坏环境。这些措施包括源头控制(流域/景观工程管理)、法规(包括区划)、经济手段、有效的洪水预警系统、洪水风险评估系统、提高洪水风险意识和洪水相关数据库等。在大多数脆弱地区,仅靠工程措施不能实现洪水安全,必须通过非工程措施进一步降低洪水风险,即只有因地制宜地将工程与非工程措施结合,才可能适当解决洪水安全问题。由于可持续发展需要考虑到后代,因此气候变化问题十分重要。非工程措施可应用于适应气候变化的策略。气候变化影响评估具有较大的不确定性,因此所采用策略的灵活性特别重要。 | Z.W.库德泽威奇 郑丰 | 2003 | 水利水电快报2003,24,24: | 3 |

| 5 | FACILE HYDROTHERMAL SYNTHESIS AND GROWTH KINETICS OF Fe-BASED MAGNETIC NANOPARTICLES显示文摘The facile hydrothermal method was used to synthesize Fe3O4 nanoparticles with an average diameter of 11nm. The pure body-centered cubic (bcc)-Fe nanoparticles were prepared by reduction of Fe3O4 nanoparticles powder in H2 atmosphere. The structure, morphology and magnetic properties of the products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis-differential scanning calorimetry (TGA-DSC) and vibrating sample magnetometer (VSM). The results showed that the as-prepared Fe3O4 nanoparticles had a relatively homogeneous size. The particle diameters became bigger with the increase of reaction time. The growth kinetics of the Fe3O4 nanoparticles was also briefly discussed. The products exhibited superparamagnetic properties at room temperature and the specific saturation magnetization was dependent on the particle sizes. | C.X. You J.C. Zhang Y. Shen Z.W.

| 6 | Improving the hard magnetic properties by intragrain pinning for Ta doped nanocrystalline Ce-Fe-B alloys显示文摘To develop Ce based permanent magnets with high performance/cost ratio, Ta doping is was employed to enhance the magnetic performance of Ce-Fe-B alloys. For melt spun Cei7Fe78-xTaxB6 (x = 0-1) alloys, the coercivity Hc increases from 439 to 553 kA/m with increasing x value from 0 to 0.75. Microstructure characterizations indicate that Ta doping is helpful for grain refinement. A second phase of TaB2 is observed in Ce17Fe77.25Tao.75B6 alloy, which acts as the pinning center of the magnetic domains, resulting in the change of coercivity mechanism from nucleation type to nucleation +pinning type. The micromagnetic simulation confirms that non-magnetic particles within hard magnetic phase can increase the demagnetization field around them and it is crucial for preventing the further magnetization reverse by pinning effect. Take the advantage of Ta doping for enhancing the coercivity, Ce content of Ce-Fe-B alloy can be further cut down to increase the remanence Jr due to the reduced volume fraction of CeFe2 phase and increased Fe/Ce ratio. As a result, a good combination of magnetic properties with Hc = 514 kA/m, Jr = 0.49 T, and the maximum energy product (BH)max = 36 kJ/m^3 have been obtained in Ce15Fe79.25Tao.75B6 alloy. It is expected that the present work can serve as a useful reference for designing new permanent magnetic materials with low-cost. | J.S.Zhang W. Li X.F. Liao H.Y. Yu L.Z. Zhao H.X. Zeng D.R.
