On some projectively flat polynomial （α,β）-metrics

In this paper, we consider some polynomial (α,β)-metrics, and discuss the sufficient and necessary conditions for a Finsler metric in the form F=α a1β a2β2/α a4β4/α3 to be projectively flat, where ai (i=1,2,4) are constants with a1≠0, α is a Riemannian metric and β is a 1-form. By analyzing the geodesic coefficients and the divisibility of certain polynomials, we obtain that there are only five projectively flat cases for metrics of this type. This gives a classification for such kind of Finsler metrics.     

第27、28届奥运会女排运动员身体形态和网上高度的比较研究

以27、28届奥运会女子排球决赛队员为研究对象,运用数理统计方法,对其身体形态和扣球高度、拦网高度等部分非技术指标进行统计分析.结果显示,从27、28届奥运会比较来看,女排队员身高、体重无显著差异,但两届奥运四强队员身高、体重占优,显示世界女排队伍继续朝着大型化方向发展;近两届奥运会女排队员年龄差距不大,而28届奥运主力队员和四强队员的年龄略高,达26岁,预示本届奥运后队员部分调整的可能性和必要性;网上高度的四项指标于比赛名次密切相关,亚洲球队在扣球和拦网高度方面与世界优秀强队有差距,但在相对弹跳力发展方面取得进步,从而缩小了网上高度差.中国女排在身高、体重、四项网上高度指标上都显示出世界一流强队的水平.     

视觉文化与当代小说中女性形象的变迁

视觉文化不仅为我们带来了大量的影像,更为重要的是,它颠覆了人们传统以来的世界观和生活方式。从根本上讲,这种变化是从以语言为中心的意象转向以视觉为中心的形象。在当代小说中,则无疑呈现出一些新的审美风貌。     

明代建阳书坊刊刻小说之概况

福建建阳是宋元明三代的刻书中心之一,在明代刊刻了大量小说,尤其以万历年间为小说刊刻高峰期。明代建阳书坊的小说刊刻具有明显的地域特征,其语体选择以白话小说居多,题材类型多集中于讲史、神魔、公案,版式多为上图下文。     

Development and implementation of a three-dimensional (3D) printing elective course for health science students

Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.

承德市森林植被净初级生产力的遥感估算

以承德市的森林分布区为研究区域,基于改进的光能利用率模型,利用2008年MODIS/NDVI产品和地面气象站点数据,结合土地覆被类型,估算承德市森林植被的年净初级生产力,并分析其时空分布格局.研究结果表明:2008年承德市森林NPP的总量为1.075×108 g.a-1,年平均值为424.59 g.m-2.a-1,NPP最高值为656.78 g.m-2.a-1.总体空间分布趋势是东南高,西北低,其季节变化较明显,呈单峰型.
