Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Design and Implementation of Furniture Placing Simulation System Based on Virtual Technology [PDF]
, 2015 在当今年代，计算机信息技术迅速发展，已成为现代生活中不可或缺的一部分，也是计算机应用技术研究中极具热点的研究课题。计算机技术的迅猛发展其中之一原因就归结于商业利益的驱动。商业的驱动使得虚拟技术变得尤为重要，也日渐成熟。虚拟技术也渐渐用于各行各业，其重要性也日渐突出。 在我国，房地产火热发展，从而对装修工程的需求不断兴起。在装修设计中，家具的模拟摆设具有很重要的作用。特别是近年来，随着生活水平的提高，消费者开始注重生活的品质。对于室内的摆设不再是堪用即可，消费者更注重家具的摆设，以提高生活的物质和精神享受。

Distribution patterns of 210Po and 210Pb and particle export in the Taiwan Strait [PDF]
, 2015 台湾海峡是南海和东海之间物质和能量交换的重要通道。黑潮分支、南海暖流以及大陆沿岸流等多种水系携带众多物质在此交汇并发生互相作用，形成了复杂、多变的海水环境。在几天至季节时间尺度上，海水环境可发生显著变化。因此，采用合适半衰期的放射性同位素能揭示一定时间尺度上海水环境的宏观变化。鉴于台湾海峡颗粒动力学研究很少，本论文以台湾海峡西部海域为重点研究海域，选择适合于研究季节变化的210Po-210Pb同位素指标，开展台湾海峡颗粒动力学过程的初步研究。论文对台湾海峡沿岸地区210Po ...
