碳中和背景下配电网差异化节能降耗潜力评估分

为了提高配电网差异化节能降耗效果，解决现有潜力评估方法存在的应用性能差的问题，提出碳中和背景下配电网差异化节能降耗潜力优化评估方法。根据配电网的空间结构，构建相应的等值电路模型。在该模型下，从设备损耗和运行附加损耗2个方面计算配电网的损耗量。根据损耗量计算结果，确定配电网差异化碳中和节能降耗方式。从静态和动态2个角度设置潜力评估指标，通过指标数据处理、指标权重求解等步骤，得出配电网差异化节能降耗潜力的综合量化评估结果。将设计潜力评估方法应用到配电网的差异化节能降耗改造工作中，能够有效降低配电网的实际线损量、降低区域损耗费用，并具有较高的应用价值。     

Beyond “Big Eaters”: The Versatile Role of Alveolar Macrophages in Health and Disease

Macrophages act as immune scavengers and are important cell types in the homeostasis of various tissues. Given the multiple roles of macrophages, these cells can also be found as tissue resident macrophages tightly integrated into a variety of tissues in which they fulfill crucial and organ-specific functions. The lung harbors at least two macrophage populations: interstitial and alveolar macrophages, which occupy different niches and functions. In this review, we provide the latest insights into the multiple roles of alveolar macrophages while unraveling the distinct factors which can influence the ontogeny and function of these cells. Furthermore, we will highlight pulmonary diseases, which are associated with dysfunctional macrophages, concentrating on congenital diseases as well as pulmonary infections and impairment of immunological pathways. Moreover, we will provide an overview about different treatment approaches targeting macrophage dysfunction. Improved knowledge of the role of macrophages in the onset of pulmonary diseases may provide the basis for new pharmacological and/or cell-based immunotherapies and will extend our understanding to other macrophage-related disorders.     

多堆厂址始发事件分析探讨

多堆厂址一级概率安全评价（PSA）研究中，机组数目的增加使得建模工作量剧增，给整个核电厂的风险评估带来困难。结合已有基础，本文研究了多堆厂址始发事件分析的筛选方法，提出利用堆芯损伤频率（CDF）上下限值评估方法，分析厂址内不同机组数对厂址CDF的影响。结果表明，双机组厂址适合优先进行具体分析。针对双机组核电站，对多堆厂址内各始发事件进行筛选。结果表明，丧失厂外电、丧失热阱等事件适合建模分析，并对其他筛选结果给出后续分析建议，为多堆厂址一级PSA后续事故序列建模工作提供了重要基础。     

Hydrocarbon potential of Permian coals of South Karanpura Coalfield,Jharkhand, India

The present study investigates the hydrocarbon generative potential of the coal seams of Barka Sayal Area of South Karanpura Coalfield, India, using petrological and geochemical characteristics. These coals are vitrinite rich followed by liptinite and inertinite. Rank wise these are sub-bituminous ‘A’ to high volatile bituminous ‘C’ and fall in the early catagenesis stage of evolution. The presence of Type III kerogen and high hydrogen index value indicates excellent gaseous hydrocarbon generative potential, but low T_max suggests a characteristic of immature source rock. The calculated high conversion (%) and sufficient oil yield (%) justifies the suitability of these coals for liquefaction processes.     

秋里塔格构造带盐下构造层变形特征及油气勘探潜力

秋里塔格构造带位于库车坳陷中部,受南天山造山作用的影响,发育一系列冲断构造,具明显的分层变形特征。依据地面露头和地震资料,秋里塔格构造带以古近系库姆格列木群及新近系吉迪克组膏盐岩为中心,可划分为盐上构造层、膏盐岩构造层和盐下构造层;受挤压作用,膏盐岩差异流动,在地表形成多排线性褶皱带,盐上构造层则发育逆冲推覆及反冲构造,而盐下构造层的变形特征主要受控于挤压应力和古生代古隆起,具有明显的分段性。中秋—东秋段位于新和—牙哈古隆起北坡,盐下构造层发育与克深构造带相似的冲断构造,可形成幅度高、规模较大的断背斜圈闭,油气勘探潜力大;佳木—西秋段位于温宿和西秋古生代古隆起之上,盐下构造层不发育冲断构造,盐下圈闭以低幅度断背斜和断块为主,规模不大,勘探潜力相对较小。     

蒙古国稀土矿地质特征及资源潜力

蒙古国蕴含丰富的稀土矿资源。本文通过对蒙古国成矿地质背景及典型稀土矿床进行研究,将蒙古国稀土矿床划分为碱性花岗岩型、碳酸岩型、伟晶岩型、离子吸附型、稀土砂矿型等5种成因类型,其中碱性花岗岩型和碳酸岩型是蒙古国稀土矿的主要成因类型;将蒙古国划分为3个稀土成矿省和7个稀土成矿带,并结合蒙古国成矿地质背景及矿产开发情况,初步划分出图瓦-库苏古尔稀土矿潜力区、肯特稀土矿潜力区和达兰扎达嘎德稀土矿潜力区共3处稀土矿勘查开发潜力区。
