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 ...

He jishu熔盐堆具有固有安全性和部署灵活性，能够广泛应用于多种场景。功率控制系统是确保熔盐堆安全稳定运行的关键系统之一，其在控制堆芯燃料盐温度的同时，还需要对负载变化进行快速响应，以满足基于熔盐堆的多样化复合能源系统中的潜在需求。控制目标之间存在相互影响，且执行器的数量和可调范围往往有限，因此给控制器参数的选择带来了巨大挑战。本文使用反应堆功率控制系统上普遍采用的比例-积分-微分（Proportional-Integral-Derivative，PID）控制器对堆芯温度和功率进行控制。在MATLAB ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

面向工程应用的先进绝热压缩空气储能模型及先进㶲分析 [PDF]
全球能源互联网先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system，AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200 MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进分析。结果表明 ...
