China's Green Economic Growth and the Corresponding Energy Transformation [PDF]
, 2016 资源耗竭和环境污染已经成为中国可持续发展的严重制约，特别是雾霾等环境问题的大面积集中爆发，更是将这一问题摆在了公众和政府的面前。但是，对于中国这样的发展中大国，“发展是第一要务”，因为解决十三亿人口的吃饭和就业问题都离不开经济较快增长。如何在稳增长、资源节约、环境友好这三者之间的权衡取舍是政府面临的难题。因此，对于中国社会经济的可持续发展，关键是在兼顾经济增长的同时尽可能实现资源节约和环境改善。这就需要实现绿色经济增长的转型。 另一方面，气候目标成为中国经济发展的约束条件 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

考虑电-气-碳综合交易的跨国电网分散式电力调度—以规划的东北亚跨国电网为例 [PDF]
全球能源互联网, 2019 为了实现跨国电网的有序发展与协调运行，跨国层面的电力交易、天然气交易和碳交易的有机结合十分关键。为此，以电力系统为核心，考虑天然气交易与碳交易的相关耦合因素，建立了跨国电-气-碳综合交易模型。在上述综合交易的框架下，建立了跨国电网的动态电力调度模型，以实现全局效益的最大化。进一步地，为了保护各个国家的工业信息隐私，提出了分散式的跨国电力调度算法，将全局优化问题转化为各个国家的子问题迭代求解，得到满足给定精度的全局最优解。最后，对东北亚跨国电网仿真算例进行测试，分析讨论在不同电-气 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Soft‐magnetic materials (SMMs) are indispensable for electrification and sustainable energy systems, yet their inherent mechanical fragility fundamentally limits applications under severe mechanical stresses. Enhancing the yield strength of SMMs is essential to prevent the degradation in magnetic performance and failure from plastic ...

Guangtongxin yanjiu, 2009 文章仿真验证了在差分相移键控（DPSK）解调时,通过调整延时线干涉仪（DLI）两臂的相对延迟来优化自由光谱范围（FSR）,使其大于传输比特率,能够获得比传统1 bit延迟更好的传输性能,并得到了FSR的最优值。优化FSR后的DPSK解调系统对光信噪比（OSNR）灵敏度和色度色散容限范围均有改善,对偏振模色散（PMD）的容忍度没有明显提高。
