马来酸酐接枝聚烯烃类热塑弹性体 (TPEg)对尼龙 6有显著的增韧效果。研究了基体粘度和界面改性剂 (CE-96 )的使用对尼龙 6 / TPEg共混体系缺口冲击强度的影响。在 TPEg分散相粘度大于尼龙 6基体粘度情况下 ,TPEg对高粘度尼龙 6的增韧效果明显好于低粘度尼龙体系。CE- 96的加入通过增大尼龙 6基体粘度和增强界面偶联显著地改善了 TPEg分散质量。在给定的分散相含量下 ,分散相颗粒尺寸的减小更有利于引发基体剪切屈服。

宪政的基本精神是控制国家权力。在控制国家权力的各种模式中,行政诉讼作为一种技术性、中立性、程序性和规则性的方式,包含着其他权力控制模式难以具备的优势。行政诉讼经过重新设想与建构,可以成为当代中国宪政建设的逻辑起点和突破口。

在变风量空调温度控制系统研究中,空调系统本身存在的多变量、时变性、干扰大等问题,传统算法很难起到很好的控制效果。针对传统控制算法的缺陷和控制上的难点,提出变论域思想在变风量空调温度控制系统上的应用。应用种在传统模糊PID控制的基础上,引入变论域思想,设计了一种变论域模糊PID算法的控制器。最后将模糊PID控制算法和变论域模糊PID控制算法对变风量空调房间温度分别进行控制仿真研究。仿真结果表明,变论域模糊PID控制算法控制效果更佳,具有超调量小、响应速度快和鲁棒性好的优点,为变风量空调系统的智能控制设计提供了一种具有可行性的方法。

目的:检验数值天气预报模式(WRF)在雅砻江下游对强降水的预报能力,并找出表现最优的参数化方案组合。创新点:首次针对雅砻江流域检验WRF模式对强降水的预报能力,并加入了计算时间作为评价的重要参考。方法:通过三场强降水事件,利用七种常用的云微物理参数化方案(Kessler,Lin et al.(Lin),SingleMoment 3-class(WSM3),Single-Moment 5-class(WSM5),Ferrier,Single-Moment 6-class(WSM6),和New Thompson et al.(NTH))和3种积云对流参数化方案(Kain-Fritsch(KF),Betts-Miller-Janjic(BMJ)和Grell-Devenyi(GD))的组合,对WRF模式在雅砻江下游的降水预报能力进行检验。为了评价WRF模式的预报能力,引入探测率(POD),空报率(FAR),BIAS和公平预报评分(ETS),对比不同方案组合的降水空间分布和站点预报的有效性。同时,均方根误差(RMSE)等指标被用来评价面雨量预报的精确性。除常规评价外,还将计算时间作为方案评价的重要参考,在满足精度需求的前提下优先选择计算效率高的方案组合。结论:***模式能够适用于雅砻江下游强降水预报;***3以及GD参数化方案组合的表现最为有效和稳定。
