Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Gaoya dianqi, 2013 由于绝缘需要,高压监测设备的电源无法由低压侧直接供给,因此,研究经高压侧取能的供电技术十分必要,而电源供能的稳定性与长期性是对其性能提出的要求。以电流互感器电磁感应取能为基础,引入C8051F021单片机构建电源控制电路,从提高电源自适应能力的角度尝试解决上述问题。该电路的取能部分、过流保护部分及后备电源部分均能由单片机通过对采样点信号进行分析而得到有效控制,可分别解决一次电流宽范围变化下的可靠取能问题,即大电流下的过流保护问题,以及欠电流下的供能问题。这使供电电源能够有效应对不稳定的电流状况,具备长期、

Gaoya dianqi, 2023 随着能源转型的深入，风光等可再生能源大规模替代传统能源发电并网，电力系统结构发生很大的变化，导致电网惯性变低、稳定性变弱。另外，风力发电功率的波动性将导致电力系统调度困难。因此，在风电并网系统中增加构网型储能系统，并给出构网型储能系统的控制策略，进而围绕风电并网的稳定性以及电压跌落故障，对构网型储能系统增加前后风电并网波形进行对比分析，验证了构网型储能系统可以大大提高风电并网的稳定性，并且对电压跌落故障有很好的抑制作用。

Gongye shui chuli, 2012 增大电极比表面积是提高电容去离子效率的方法之一．通过研究活性炭负载量对电极比表面积的影响，探讨了一种提升炭电极电容去离子性能的有效方法．实验结果表明，增加活性炭负载量可有效提升电极比表面积，电极电容最高可达0.56 F/cm2，表现出较好的电容去离子性能．持续增加活性物质虽对电极内电阻影响较小，但不能进一步提高电极吸附表面，比电容急剧下降．优化电极孔隙结构是提升活性炭电极电吸附性能的有效方法．
