发现了采用减量化重稀土镝添加高效制备块状超高矫顽力稀土永磁体新型方法。在钕铁硼（nd-Fe-B）系稀土永磁材料中以DyH3的形式掺入稀土镝（Dy）元素,在不同烧结温度1020,1040,1050,1060,1080℃下进行烧结,制备成一系列DyH3掺杂（Prnd）30Fe69B磁体和未掺杂的（Prnd）30Fe69B磁体。研究剩磁、矫顽力与烧结温度及显微结构之间的关系。结果显示：随着温度的升高,剩磁不断上升;矫顽力在烧结温度1020-1050℃时达到最大。重稀土Dy添加可有效增加nd-Fe-B磁体的矫顽力。采用扫描电镜和能谱仪研究了不同烧结温度对磁体晶粒尺寸、Dy在晶粒内与晶界处成分分布的影响,发现温度超过1060℃时,晶粒会过度长大,使其矫顽力随之下降。稍低的烧结温度1020-1050℃可以获得Dy分布于晶粒呈＂壳＂状结构并使得Dy尽量分布于晶界处,获得了制备高矫顽力块体稀土永磁较满意的Dy减量化方法。

Prevailing city design in many countries has created sedentary societies that depend on automobile use. Consequently, architects, urban designers, and land planners have developed new urban design theories, which have been incorporated into the Leadership in Energy and Environmental Design for Neighborhood Development （LEED-nd） certification system. The LEED- nd includes design elements that improve human well-being by facilitating walking and biking, a concept known as walkability. Despite these positive developments, relevant research findings from other fields of study have not been fully integrated into the LEED-nd. According to Zuniga-Teran （2015）, relevant walkability research findings from multiple disciplines were organized into a walkability framework （WF） that organizes design elements related to physical activity into nine categories, namely, connectivity, land use, density, traffic safety, surveil- lance, parking, experience, greenspace, and community. In this study, we analyze walkability in the LEED-nd through the lens of the nine WF categories. Through quantitative and qualitative analyses, we identify gaps and strengths in the LEED-nd and propose potential enhancements to this certification system that reflects what is known about enhancing walkability more comprehensively through neighborhood design analysis. This work seeks to facilitate the translation of research into practice, which can ultimately lead to more active and healthier societies.

Research from multiple domains has provided insights into how neighborhood design can be improved to have a more favorable effect on physical activity, a concept known as walkability. The relevant research findings/hypotheses have been integrated into a Walkability Framework, which organizes the design elements into nine walkability categories. The purpose of this study was to test whether this conceptual framework can be used as a model to measure the interactions between the built environment and physical activity. We explored correlations between the walkability categories and physical activity reported through a survey of residents of Tucson, Arizona （n=486）. The results include significant correlations between the walkability categories and physical activity as well as between the walkabi[ity categories and the two motivations for walking （recreation and transportation）. To our knowledge, this is the first study that reports links between wa[kability and walking for recreation. Additionally, the use of the Walkability Framework allowed us to identify the walkability categories most strongly correlated with the two motivations for walking. The results of this study support the use of the Walkability Framework as a model to measure the built environment in relation to its ability to promote physical activity.

Purpose: The purpose of this study was to evaluate the change in corneal wavefront aberrations in young adults who have been fit with multifocal soft contact lenses for myopia progression control. Findings have been analyzed for statistical significance and clinical relevance and compared to reportedly successful Orthokeratology outcomes. Methods: The dominant eye of 40 participants (27 women, 13 men;mean age 27.3 ± 3.2 years;range 23 to 39 years) was fit with Proclear Multifocal center distance lenses (Coopervision, Pleasanton, USA) having a variety of distance powers and reading additions. Refractive errors were limited to a range of –6.00 D up to +1.00 D of sphere, and no greater than –1.00 D of cylinder. Corneal wavefront measurements were performed over 6 mm diameters with a Zeiss Atlas 9000 corneal topographer (Zeiss Meditec, Dublin, USA) prior to, and following lens fitting. Data were converted into rectangular Fourier optics terms M, J0, J45 and RMS values for each reading addition were statistically analyzed. Following evaluation of statistical significance and clinical relevance, results were compared to published data from successful Orthokeratology treatments. Results: Statistically significant changes in higher order aberrations were detected for lenses of all reading additions. Lens groups with higher Add-powers demonstrated stronger changes with increased significance. Final RMS values relating to 2nd, 3rd and 4th Zernike Orders reached clinical significance with a wavefront error of 0.10 μm, the equivalent of 0.25D. Moreover, as Add-powers increased, 3rd and 4th order aberrations likewise showed an increase. Pre-fitting astigmatism values accounted for the highest recorded aberrations and remained predominantly unchanged. Conclusion: Proclear Multifocal center-distance contact lenses were found to increase higher order wavefront aberrations in a manner dependent on their Add-power. In comparison to successful Orthokeratology outcomes, the amounts of

抢劫和入室盗窃犯罪行为是日常生活中最长见的违法行为,而这两种违法行为的发生有一定的规律可循。例如抢劫行为主要发生在市中心、CBD和商业中心的人群、商铺密集区域,而入室盗窃则多发生于生活社区及其周边地带。然而,想要防范这两种犯罪行为需要根据实际情况进行分析和比对,结合分析结果提出准确合理的警力部署。美国内布拉斯加州林肯市警察局针对该市抢劫和入室盗窃犯罪行为高发的情况,需要针对具体分析结果对于警力进行部署,主要针对徒步巡逻和是否需要对住户进行入户警示进行分析,根据分析结果进行具体部署。本文中使用的分析方法为紧邻层空间聚类分析(NNH)和针对犯罪的空间和时间分析法(SPAC),分别对林肯市入室行窃和抢劫的数据进行分析并尝试将两种方法进行对比以便给出更加科学的分析报告。
