全球能源互联网, 2019 伴随风电大规模接入电网，其不确定性为电网的决策调度带来了新的挑战，风电消纳评估由此成为研究热点之一。以不确定集合表征风电不确定性，建立了两阶段鲁棒优化模型，以解决电-热综合能源系统的风电消纳能力评估问题。主问题基于风险指标优化风电可消纳域，并在算法处理中引入分段线性化处理非线性的风险表达式；子问题引入风电可接纳判据寻求风电不确定集合中的极端场景。最后着重比较电-热综合能源系统与电力系统的风电消纳能力差异。

Wildlife Letters, EarlyView.Migratory shorebirds traveling the East Asian–Australasian Flyway face systemic policy fragmentation and habitat disconnection between China (coordination challenges and renewable energy conflicts) and Australia (federal governance fragmentation). This study proposes a transboundary conservation framework to fill this gap.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Zhejiang Daxue xuebao. Lixue ban, 1999 用INDO方法研究了氮杂与硼杂碳笼CnX(n=59,69;X=N+,B-)的电子结构和光谱,表明CnX与C60,C70相比将发生结构畸变,氮杂碳笼比硼杂碳笼稳定,C70中靠近极附近的两种C原子易被杂原子置换.本文在对电子跃迁进行理论指认的同时,讨论了光谱红移的原因.

全球能源互联网, 2019 当前中国正处在能源结构转型的关键阶段，传统能源结构的利用效率受限，多种能源相互协同发展受阻，经济效益也徘徊在较低水平。以能源革命为背景，发展综合能源系统是能源结构转型的重要组成部分。其以智能电网为核心枢纽，结合电网、天然气网、热传输网以及多能耦合设备，利用多种能源的耦合性和互补替代性，不仅可弥补可再生能源的间歇性和随机性波动等问题，也可加强供给侧和需求侧的相互响应，提高综合能源利用效率，通过协同方式实现资源的最佳配置。目前中国综合能源系统示范工程大多在工业园区落成，因此围绕工业园区综合能源系统这一背景 ...

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

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 ...
