| 1 | 基于改进混沌粒子群算法的多源独立微网多目标优化方法显示文摘针对目前独立微网优化运行中微源类型与场景设计较为简单、未充分考虑可控负荷作用等问题,以可控负荷作为网内功率平衡的辅助手段,研究多源独立微网的调度优化问题。建立了使发电成本、切负荷补偿成本及微网环境效益最优的多目标优化模型。根据工作日、周末和晴、阴雨天组合设计了四种典型场景,在满足功率平衡等约束的前提下实现独立微网的经济调度。针对优化变量多、场景复杂的微网优化模型,提出了改进的混沌粒子群算法(Chaos Particle Swarm Optimization,CPSO)用于优化问题求解,验证了模型和算法对不同场景微网优化问题的有效性。 | 苏适 周立栋 陆海 陈奇芳 严玉廷 N.A.

| 2 | 微波能在钛铁矿选矿中的应用显示文摘本文首次将微波能作为一种预处理技术用于钛铁矿的选矿。研究内容包括:微波能在磨矿、磁选和浮选中的应用.钛铁矿和磁铁矿在微波场中被选择性地介电加热至一相当高的温度,而与之共生的硅酸盐等脉石矿物不被迅速加热。这种微波射线对钛铁矿矿石中各矿物的选择性加热导致钛铁矿矿不内部产生强的应力,促进矿石内部矿物相之间的有价粒间裂隙的形成,从而提高了矿石的可磨度,增进了矿物的粒间解高,提高了钛铁矿的磁选分离效率.微波照射预处理同时加速了钛铁矿表面亚铁离子氧化成三份铁离子,加强了油酸根离子在其表面的吸附,从而大幅提高了钛铁矿的浮选回收率. | 范先锋 N.A.罗森 | 1999 | 国外金属矿选矿1999,36,2: | 18 |

| 4 | 钛铁矿活化浮选显示文摘本文介绍了一种实用的钛铁矿活化浮选方法、Ph(NO3)2用作活化剂.试验用矿石样品来自挪威.结果表明:当Nb(NO2)2用量为60g/t时,钛铁矿浮选回收率由65%提高至83%。精矿含TiO236.6%矿物表面电位调查表明:铅离子选择性地吸附于钛铁矿的Helmholtz层,加强了油酸根离子在钛铁矿铁矿表面的吸附.Pb(NO3)2不能活化石英等硅酸盐矿物. | 范先锋 N.A.罗森 | 1999 | 国外金属矿选矿1999,36,4: | 10 |

| 14 | 印度和巴基斯坦在印度河水系上的合作显示文摘尽管印度和巴基斯坦的合作受到了多方赞许,但很多学者认为这种合作是被动的,因为《印度河用水条约》(IWT)切断了两国相互依存的关系。而本文试图说明,印巴两国在印度河水系的管理方面仍然保持着相互依赖的关系,并且40多年来,他们一直保持着积极的合作,双方为了尊重对方意愿而均对本国政策进行了调整。印度河常设委员会(PIC)的规划为双方合作提供了便利并使得合作得以维持。PIC的冲突解决机制为双方和平管理印度河创建了平台。 | N.A.扎瓦赫里 李红梅 | 2011 | 水利水电快报2011,32,5: | 2 |

| 18 | 中国与俄罗斯农业合作状况与发展思路显示文摘农业是人类的生存之本,也是中国的根基产业。自'一带一路'倡议提出以来,中国农业农村部等部门,不断开辟新的领域,积极推动与沿线国家的农业合作发展。俄罗斯是中国'一带一路'战略的重要合作伙伴,两国长期在农业方面互有合作,但目前合作的规模还较小,效率还较低,尚未达到预期效果。在经济全球化趋势愈加明显的背景下,中俄两国应抓住机遇,不断深化两国在农业方面的合作,以推动双方农业经济发展。本文通过简述俄罗斯农业现状,并通过对两国在农产品贸易、农业投资、农业教育与科技合作等方面的具体情况与存在问题进行分析,提出了推动中俄两国农业合作的思路,以期为国内各部门和相关企业与俄罗斯开展农业合作提供参考。 | 叶霄 N.A.科甘诺娃 张雄 周评平 叶鹏盛 | 2021 | 中国农学通报2021,37,11: | 2 |

| 20 | 临床检查可预测下肢周围动脉疾病?显示文摘Context: Lower extremity peripheral arterial disease(PAD) is common and associated with significant increases in morbidity and mortality. Physicians typically depend on the clinical examination to identify patients who need further diagnostic testing. Objective: To systematically review the accuracy and precision of the clinical examination for PAD. Data Sources, Study Selection, and Data Extraction: MEDLINE(January 1966 to March 2005) and Cochrane databases were searched for articles on the diagnosis of PAD based on physical examination published in the English language. Included studies compared an element of the history or physical examination with a reference standard of ankle- brachial index, duplex sonography, or angiogram. Seventeen of the 51 potential articles identified met inclusion criteria. Two of the authors independently extracted data, performed quality review, and used consensus to resolve any discrepancies. Data Synthesis: For asymptomatic patients, the most useful clinical findings to diagnose PAD are the presence of claudication(likelihood ratio [LR], 3.30; 95% confidence interval [CI], 2.30- 4.80), femoral bruit(LR, 4.80; 95% CI, 2.40- 9.50), or any pulse abnormality(LR, 3.10; 95% CI, 1.40- 6.60). While none of the clinical examination features help to lower the likelihood of any degree of PAD, the absence of claudication or the presence of normal pulses decreases the likelihood of moderate to severe disease. When considering patients who are symptomatic with leg complaints, the most useful clinical findings are the presence of cool skin(LR, 5.90; 95% CI, 4.10- 8.60), the presence of at least 1 bruit(LR, 5.60; 95% CI, 4.70- 6.70), or any palpable pulse abnormality(LR, 4.70; 95% CI, 2.20- 9.90). The absence of any bruits(iliac, femoral, or popliteal)(LR, 0.39; 95% CI, 0.34- 0.45) or pulse abnormality(LR, 0.38; 95% CI, 0.23- 0.64) reduces the likelihood of PAD. Combinations of physical examination findings do not increase the likelihood of PAD beyond that of individual clinical findings. However, when combinations of clinical findings are all normal, the likelihood of disease is lower than when individual symptoms or signs are normal. A PAD scoring system, which includes auscultation of arterial components by handheld Doppler, provides greater diagnostic accuracy. Conclusions: Clinical examination findings must be used in the context of the pretest probability because they are not independently sufficient to include or exclude a diagnosis of PAD with certainty. The PAD screening score using the hand- held Doppler has the greatest diagnostic accuracy. | Khan N.A. Rahim S.A. Anand S.S. 任付先 | 2006 | 世界核心医学期刊文摘(心脏病学分册)2006,2,6: | 2 |
