Renewable energy has penetrated power grid enterprises on a large *** to the intermittency and volatility of renewable energy generation,it is necessary to build new flexible grid-side resources to ensure the safe and stable operation of the power grid,which will cause great pressure on cost allocation for power grid *** article considers four types of flexible grid-side resources and constructs a dual-level configuration optimization model for flexible grid-side resources under the penetration of renewable en*** on the configuration results,the cost scale of flexible grid-side resources is estimated and an improved ancillary service cost allocation model based on the Shapley value method is proposed to smooth the allocation of ancillary service costs in the cost of flexible grid-side resources between the two main bodies of renewable energy and *** calculation results show that,when the penetration rate of renewable-energy power is 30%and 35%,respectively,the cost of flexible grid-side resources is 9.606 billion yuan and 21.518 billion yuan,*** proportion of ancillary service costs allocated to load is relatively high-about five times that of the ancillary service costs allocated to renewable energy-and the higher the penetration rate of renewable energy,the higher the proportion of ancillary service costs allocated to renewable energy.

论文主要依据中国第一历史档案馆及台北“中央研究院”馆藏有关原始档案,对清末小吕宋中西学堂发展历史予以补正,并由此讨论近代东南亚华文教育之开拓历史。研究显示,小吕宋中西学堂之创办,与19世纪末菲律宾国内形势变化、海外华校出现及清朝首任驻菲总领事陈纲密切相关。中西学堂创办之初即开设中、英文课程而非只开设中文课程。学堂创办经费主要从收取华人护照费盈余中拨充而非由善举公所捐费。1908—1911年,中西学堂办学发生重大改革,包括推行“癸卯学制”以及扩办为华侨公立初等商业学校。小吕宋中西学堂开办后,东南亚各地华校如雨后春笋般出现。

2023年11月15日中美元首峰会圆满落幕,双方在政治外交、人文交流、全球治理、军事安全等方面达成了共识,也向世界传出了积极的信号。虽然今后两年将是中美关系缓和的关键之年,但我们认为,美国对华构建的“小院高墙”不会撤去,在高科技领域对华限制仍会继续,那么美国与西方的选择性是否致命,中国是否能够破局,关系到百年未有之大变局下,守成大国与崛起大国战略竞争的前途。如今,美国主要是从经济安全的角度管控风险,摆脱重要供应链对中国的依赖,但同时又要维持地区间的稳定关系,即“去风险化”,它既有选择性的合作,又有选择性的“脱钩”。对此,我们不仅要加快“卡脖子”技术上的突破,与美国保持尽可能多的经贸关系,加强与欧洲国家以及日韩的经贸合作,而且,更重要的是要形成两条腿走路的科技创新之路,增强经济安全,维护中国的全球利益。

雨水中新污染物(ECs)识别逐渐受到广泛关注,掌握其在降水过程赋存及迁变特性成为雨水资源化利用的关键.选取典型屋面,研究了2023年春季3~5月期间6场降雨事件不同集汇过程中雨水水质状况及ECs赋存差异,采用主成分分析(PCA)和相关性分析,探明了屋面雨水集汇过程中ECs归趋特性.结果表明,54种目标ECs在净湿沉降、干湿沉降和屋面径流过程中共检出44种,总浓度范围为63.0~432.4 ng·L^(-1)(平均值为166.8 ng·L^(-1)).其中,双酚A(BPA)浓度水平最高,其范围为14.7~265.6 ng·L^(-1)(平均值为62.5 ng·L^(-1)),其次为氧氟沙星(OFX)和甲氧基肉桂酸乙基己酯(EHMC);溶解性有机质(DOM)、氮污染物和颗粒物是影响ECs赋存特性的重要因子,Mantel相关系数最高可达0.98(P<0.01);初期雨水集汇过程中净湿沉降的ECs浓度最高,而后期干湿沉降和屋面径流的ECs浓度较高,干、湿沉降对屋面径流的ECs平均贡献率分别为21.48%和78.52%,药品与个人护理品(PPCPs)、内分泌干扰物(EDCs)和农药等在集汇过程中超30%沉积在屋面.研究结果可为城市屋面径流中的ECs识别和控制以及雨水安全利用提供科学理论依据.

气候变暖和大气氮沉降对草地生态系统功能有重要影响。然而,降水变化如何调节荒漠草原生态系统生产功能对气候变暖和氮沉降的响应还不清楚。本研究基于内蒙古短花针茅(Stipa breviflora Griseb.)荒漠草原长期增温和氮添加试验平台,分析两个连续降水差异较大年份中植物生产力和生态系统碳交换对增温和氮添加响应的不同。结果表明:(1)植物群落地上生物量在干旱和湿润年份有显著差异。在干旱年份,氮添加使得C_(3)植物地上生物量显著降低了10.50%;在湿润年份,氮添加使得植物群落地上生物量和C_(3)植物地上生物量分别显著增加了11.69%和8.06%。(2)在干旱年份,氮添加显著促进了净生态系统碳固定,而增温显著降低了总生态系统生产力;在湿润年份,增温和氮添加对生态系统碳交换均没有显著影响。因此,野外长期监测结合年际间降水波动对分析全球变化影响草原生态系统功能十分必要。
