Diagnosis of Moist Vorticity and Moist Divergence for a Heavy Precipitation Event in Southwestern China

引用

Advances in Atmospheric Sciences 2017年第1期34卷 88-100页

作者： Gang LI daoyong yang Xiaohua JIANG Jing PAN Yanke TAN Xichang Satellite Launch Center Xichang 615000China State key Laboratory at Numerical Modelling for Atmospheric Sciences and Geophysical Fluid Dynamics Institute of Atmospheric PhysicsChinese Academy of SciencesBeijing 100029China College of Meteorology and Oceanography PLA University of Science and TechnologyNanjing 211101China

A regional heavy precipitation event that occurred over Sichuan Province on 8-9 September 2015 is analyzed based on hourly observed precipitation data obtained from weather stations and NCEP FNL data. Two moist dynamic parameters, i.e., moist vorticity （mζ and moist divergence （mδ）, are used to diagnose this heavy precipitation event. Results show that the topography over southwestern China has a significant impact on the ability of these two parameters to diagnose precipitation. When the impact of topography is weak （i.e., low altitude）, rn（ cannot exactly depict the location of precipitation in the initial stage of the event. Then, as the precipitation develops, its ability to depict the location improves significantly. In particular, m（ coincides best with the location of precipitation during the peak stage of the event. Besides, the evolution of the m（ center shows high consistency with the evolution of the precipitation center. For mδ, although some false-alarm regions are apparent, it reflects the location of precipitation almost entirely during the precipitation event. However, the mδ center shows inconsistency with the precipitation center. These results suggest that both m（ and mδ have a significant ability to predict the location of precipitation. Moreover, m（ has a stronger ability than mδ in terms of predicting the variability of the precipitation center. However, when the impact of topography is strong （i.e., high altitude）, both of these two moist dynamic parameters are unable to depict the location and center of precipitation during the entire precipitation event, suggesting their weak ability to predict precipitation over complex topography.

Physiological Effects of MgO and ZnO Nanoparticles on the Citrus maxima

引用

Journal of Wuhan University of Technology(Materials Science) 2019年第1期34卷 243-253页

作者： XIAO Lian WANG Shouxia LI Junli School of Chemistry Chemical Engineering and Life Sciences Wuhan University of Technology

Toxicity of MgO and ZnO nanoparticles at concentrations of 250, 500 or 1 000 mg/L for Citrus maxima seedlings was investigated to evaluate the potentiality of their use as nano-fertilizers. Uptake and translocation of metal oxide nanoparticles and lipid peroxidation were measured and compared with those of plants exposed to the highest equivalent concentrations of Mg^(2+) and Zn^(2+). MgO nanoparticles were translocated from roots to shoots, while translocation of ZnO nanoparticles was low. Exposure to Mg^(2+) and MgO at all concentrations entailed severe toxicity and strong oxidative stress. ZnO nanoparticles showed only mild toxicity, while Zn^(2+) caused leaf vein chlorosis and strong oxidative stress to plant shoots. In conclusion, the toxicity of MgO nanoparticles to the plant resulted from the dissolved Mg^(2+) concentration, while that of ZnO nanoparticles was not correlated with the dissolved Zn^(2+) concentration. Our findings are significant for development and application of MgO and ZnO nanoparticles as nano-fertilizers in agriculture.

提出一种基于生成对抗模型的水下图像修正与增强算法.该算法将多尺度内核应用于改进的残差模块中,以此构建生成器,实现多感受野特征信息的提取与融合;判别器设计考虑了全局信息与局部细节的关系,建立了全局-区域双判别结构,能够保证整体风格与边缘纹理的一致性;最后,根据人类视觉感官系统设计了无监督损失函数,此部分无需参考图像进行约束,同时其与对抗损失和内容损失一起进行联合优化,能够得到更优的色彩和结构表现.在多个数据集上进行实验分析表明,此算法能较好地修正色偏、对比度,保护细节信息不丢失,在主客观指标上都优于典型对比算法.

规避对教育定义的各种错误应用,是确保在教育学领域进行有效知识生产的一个前提。在《教育的语言》当中,谢弗勒把教育定义区分为三类,进而逐一分析各自的功能和评判标准。据此,可以对当前研究中教育定义的实际使用情况做出评判。基于谢弗勒分析工作的六项推论,可以发现教育研究在定义使用上的常见陷阱:有相同定义项的不同研究,研究结论未必有可比性;约定型定义的定义项,无法建立稳定的研究结论;辞源分析不能确定被定义项用法,只能表明其有过某种用法;操作定义免受前期用法约束,这种便利往往被滥用;反映前期用法的准确程度,无法证成或证伪一个行动规划;对概念用法的准确描述,不能证成推导出来的行动规划。认识并规避这些教育定义的陷阱,可以提升教育研究和教育讨论的品质,推动教育学领域的知识生产。

在2022年出版的《世界中心教育》中,比斯塔把杜威视为培养范式的典型案例。他进而认为,培养范式的教育只要人适应环境,忽略了人拒绝对环境做调适的可能性。比斯塔的评论,构成了对于杜威教育理论的严厉批评。但是,在对比比斯塔与杜威的教育理论,尤其是在回顾杜威的环境概念以后可知,比斯塔和杜威在教育上有共同的反对对象,比斯塔对杜威的批评并不公允。
