作为对历史唯物主义原创性贡献的“中国方案”之一,构建人类命运共同体彰显中国共产党对人类前途命运的哲学关切,具有强大的思想和理论穿透力,其逐渐推进预示着世界历史将进入新阶段。从人类文明发展高度看,构建人类命运共同体既是中国共产党独特的世界前途观与人类发展观,也是中国共产党对“世界之问”“时代之问”的创造性解答。构建人类命运共同体,实质上是寻求一种不同于“西方中心论”的世界发展之路,为解决人类共同面临的“和平赤字、发展赤字、治理赤字、信任赤字”四大难题提供“中国方案”,贡献“中国智慧”。要站在历史唯物主义的高度,深入世界历史的本质性维度,全面理解和精准把握构建人类命运共同体的核心要义,科学阐明“中国道路”的文明底蕴,更好地揭示构建人类命运共同体这一全球治理新方案的世界历史意义。

以山东省胶州市农户调查数据为样本,实证检验农村金融对新型农业经营主体培育影响的结果表明,政府提供的通用性金融支持对农业企业的影响不显著,而对家庭农场、农民合作社以及种养大户的培育都具有正向促进作用;金融机构提供的专用性金融支持对种养大户的培育影响不显著,而对农业企业、家庭农场和农民合作社的培育具有显著的正向影响;新型农业经营主体自有资金对农业企业、家庭农场、农民合作社和种养大户的培育都具有正向显著影响。因此,农村金融制度改革要根据新型农业经营主体异质性的特点提供差异化金融支持政策。

The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange a

连锁换相失败是交直流混联电网的新型连锁故障形式之一。结合连锁关系在换相失败相关现象中的体现和参与环节,文中提出了一种在关键线路短时调节阻抗以降低耦合的抑制策略,重点讨论了策略的实施位置。在加权网络模型的基础上,基于直流分群界定了换相失败的连锁范围。在直流群内搜索对直流耦合关系影响较大的关键路径,并采用潮流介数比较各线路阻抗变化对系统运行状态的冲击,以避免在重要线路采取措施。针对不同的扰动,利用换相电压时间面积判断需要启动策略的直流群,从而实现有差别的连锁换相失败抑制。在修改的IEEE 39节点系统和某省市电网算例中,利用PSCAD/EMTDC开展仿真,结果均验证了关键线路阻抗短时调节策略抑制连锁换相失败的效率和有效性。

为研究爆燃驱动式射钉侵彻靶板深度的影响因素及规律,对直径7 mm的射钉垂直侵彻20 mm厚Q235靶板进行数值模拟.基于LS-DYNA有限元软件,选择Johnson-Cook本构模型和Gruneison状态方程对射钉侵彻靶板过程进行仿真模拟,并通过侵彻试验验证模型的合理性.采用所建立的仿真模型,模拟分析射钉的头部锥角和材料强度、炸药驱动力、射钉与靶板初始间隙等因素对Q235靶板侵彻深度的影响规律.结果表明:随着射钉头部锥角增加,侵彻阻力不断增大,射钉最大速度逐渐减小,侵彻深度及有效侵彻深度不断减小;射钉材料的静屈服强度低于700 MPa时,由于钉体发生明显的墩粗变形,侵彻深度较浅,而高于700 MPa时,射钉材料的静屈服强度对侵彻深度影响较小;炸药爆燃产生的气体压强低于150 MPa时,侵彻深度随气体压强增大近似呈线性增加,而高于150 MPa时,靶板背面变形使应力得到释放,侵彻深度显著提高;随射钉与靶板初始间隙增加,射钉在接触靶板前可获得更高的速度,侵彻深度不断增大,但超过20 mm后,初始间隙对侵彻深度基本没有影响.

构建不完全信息动态博弈和重复博弈模型,设计人为田野实验,探究农地抵押与信誉监管机制对于缓解农村信贷高利率困境的不同作用。研究结果发现:第一,利率调节在无抵押担保的信贷交易市场中失灵,农户道德风险极易导致农户与农村金融机构陷入“囚徒困境”。第二,农地抵押价值较低时,高利率政策会导致农村信贷市场呈现“柠檬市场”特征,农村金融机构占优策略是实施严格的农村信贷数量配给。第三,提高农地抵押价值可以缓解农村信贷市场的数量配给,但难以帮助农户走出信贷交易中的高利率困境。第四,信誉监管机制可以促使农村金融机构以农户接受的合理利率与农户实现长期合作,但也面临着农户项目经营失败无力还贷的风险。第五,农地抵押与信誉监管耦合推进是帮助农户走出信贷交易高利率困境、实现农户与农村金融机构长期互利共赢的有效举措。
