Global protected‐area coverage and human pressure on tidal flats
Conservation Biology, Volume 35, Issue 3, Page 933-943, June 2021., 2021 Abstract Tidal flats are a globally distributed coastal ecosystem important for supporting biodiversity and ecosystem services. Local to continental‐scale studies have documented rapid loss of tidal habitat driven by human impacts, but assessments of progress in their conservation are lacking.

State estimation of power grid under smart grid integration based on FFCD-SOGI-PLL
Xibei Gongye Daxue Xuebao, 2022 在智能电网与新能源发电融合背景下, 电力电子接口装置的大量使用将给系统引入额外的直流偏置。因此, 电网电压信息获取算法的直流偏置抑制能力变得至关重要。二阶广义积分器锁相环(SOGI-PLL)广泛应用于电网信息的同步与提取, 可以有效抑制频率波动和相位跳变对电网状态估计精度的影响, 但其自适应频率反馈环节在实现谐波抑制的同时, 对于电网中含有的直流偏置非常敏感。针对这一问题, 提出了一种固定频率反馈的级联SOGI-PLL(FFCD-SOGI-PLL), 使用级联结构输入固定电网标称频率 ...

Decision‐support tools for dynamic management
Conservation Biology, Volume 34, Issue 3, Page 589-599, June 2020., 2020 Abstract Spatial management is a valuable strategy to advance regional goals for nature conservation, economic development, and human health. One challenge of spatial management is navigating the prioritization of multiple features. This challenge becomes more pronounced in dynamic management scenarios, in which boundaries are flexible in space and ...

全球能源互联网, 2019 由于柔直电网“隔离”了频率信号，互联多区域协同调频问题亟待研究。现有研究大多利用换流站的下垂控制以及直流电压偏差实现频率信号的传递，但忽略了风电集群接入后由风电功率正常波动引起的直流电压偏差干扰，可能导致风电集群在无需调频时频繁地调整出力。对此，提出了基于直流电压偏差及其特征量的多区域协同调频策略，分别针对电网频率偏移和风电功率波动两种场景提取直流电压偏差特征量，包含电压变化量、电压变化率和滤波后的电压分量幅值3个特征，并基于二者的差异设置换流站启动下垂控制的判据。仿真结果验证了所提方法的有效性。

Jianzhu Gangjiegou Jinzhan, 2023 为研究内置型钢的方形不锈钢管超高性能混凝土柱的偏压性能，考虑长径比、宽厚比、偏心率、型钢含钢率和加载方向（强弱轴加载）等因素的影响，设计了18根试件进行偏心受压试验研究。观察试件在偏心受压状态下的破坏过程及破坏形态，并通过荷载-跨中侧向挠度关系曲线及侧向挠度曲线，分析各因素对试件偏压性能的影响。结果表明：试件的破坏形态表现为短柱的强度破坏和中长柱的非弹性失稳破坏，且伴有局部鼓曲现象产生；试件的极限承载力随着长径比、宽厚比、偏心率的增加而减小，随着型钢含钢率的增加而增大；与绕弱轴方向加载的试件相比 ...
