对120块岩样XRD、SEM分析结果表明,下二门油田纵向粘土矿物演化规律明显,浅、上层系以蒙皂石—高岭石组合为主,中、下层系为绿泥石—高岭石—伊/蒙间层组合,深层系为绿泥石—伊利石组合。发育七种粘土微结构类型,地层微粒的稳定性由占主导地位的微结构类型决定。微结构稳定性序列为层流状>绒球状>畴状>叠片支架状>絮团状>蜂窝状>支架状。预测碱敏、水敏、盐敏和出砂是最严重的地层损害方式。     

Constructing dystopian experience: A Neurath-Cartwrightian approach to the philosophy of social technology

Social situations, the object of the social sciences, are complex and unique: they contain so many variable aspects that they cannot be reproduced, and it is even difficult to experience two situations that are alike in many respects. The social scientists' past experiences that serve as their background knowledge to intervene in an existent situation is poor compared to what a traditional epistemologist would consider ideal. A way of dealing with the variable and insufficient background of social scientists is by means of models. But, then, how should we characterize social scientific models? This paper examines Otto Neurath's scientific utopianism as an attempt to deal with this problem. Neurath proposes that social scientists work with utopias: broad imaginative plans that coordinate a multitude of features of a social situation. This notion can be used in current debates in philosophy of science because we notice that utopias, in Neurath's sense, are comparable to models and nomological machines in Nancy Cartwright's conception. A model-based view of science lays emphasis on the fact that scientists learn from the repeated operation of such abstract entities, just as they learn from the repetition of experiments in a laboratory. Hence this approach suggests an approximation between the natural and the social sciences, as well as between science and utopian literature. This is exemplified by analyzing the literary dystopia We, written by Yevgeny Zamyatin, to show that reasoning from and debating about utopian writings, even if fictional and pessimistic, creates phenomena of valuation, which are fundamental for constituting a background of experiences in the social sciences.     

一种面向移动端的浅层CNN表情识别

移动端的表情识别有巨大需求,但是受算力限制,主流深度神经网络无法直接移植.为此,设计了一个浅层网络,在节约计算量的同时保证了识别率.网络中使用三组堆叠而成的卷积层,有助于增大感受野,便于更好地提取特征,这是提升识别率的关键;使用全局平均池化层,避免引入额外的全连接层,大幅降低参数量,在训练样本不足的情况下,降低模型过拟...     

社会主义市场经济条件下马克思主义理论发展的新契机

社会主义市场经济的发展,不仅在理论上与马克思主义具有内在一致性,而且在实践上为马克思主义理论的发展提供了物质土壤、鲜活因素和社会基础,为其理论的发展提供了新的契机。对于社会主义市场经济对马克思主义的影响,我们应该从挑战与契机的双重角度进行分析,才能更深刻明确地认识马克思主义的强大生命力。     

东海内陆架EC2005孔沉积物磁化率与粒度组分的相关性研究

对位于浙-闽沿岸泥质带的EC2005孔长岩芯(6 020 cm)进行了磁化率和粒度测量,分析了沉积物不同粒级组分和磁化率大小变化的相关关系.通过计算两者的相关系数,认为在整段岩芯上两者呈正相关,且磁性颗粒主要赋存在粗颗粒物质中.磁化率与>63 μm的组分含量的相关系数为0.510,而对<4 μm乃至<16 μm的组分,与磁化率呈反相关,相关系数可达-0.644.在不同沉积相中,磁化率和不同粒度组分含量的相关关系有所不同.前三角洲相和前滨相沉积物的磁化率和粒度组分没有表现出明显的相关性;三角洲前缘相和三角洲平原相沉积物磁化率和粒度的相关性与整段岩芯的相似;浅海相沉积物4～16 μm的组分与磁化率呈较强的反相关.600～2 806 cm的沉积物可能遭受了早期还原成岩作用,导致磁化率与粒度组分的相关程度降低.水动力条件是影响两者相关性的重要因素.水动力条件强,则两者相关性较好;水动力条件较弱,则两者基本不相关.磁化率和粒度组分的相关性还受到物源变化、分选程度的影响.磁化率和粒度的组合特征蕴含了一定的古气候信息.全球性的气候事件如新仙女木事件、8-2 ka冷事件在粒度参数中都有较好的响应,相比之下磁化率数据的变化幅度没有粒度数据强烈,可能与磁化率的多种控制因素有关.

Introduction to values and pluralism in the environmental sciences: From inferences to institutions

Philosophers of science continue to elaborate our understanding of the roles that values play in scientific reasoning, practice, and institutions. This special issue focuses on the environmental sciences, a mosaic of fields ranging from restoration ecology to forestry to climatology, unified by its attention to the relationships between humans and their habitats. It is a field that revolves around ameliorating environmental problems, aiming to support the provision of social goods and provide guidance to policymakers about how to regulate individuals and industries. Values abound in such judgments as setting the boundaries of an ecosystem, integrating the human dimensions of social-ecological systems, and collaborating with stakeholders. Since few in the field are likely to insist that these judgments can be made without reference to social values, environmental science can serve as fertile ground for exploring the ethical, social, and political terrain at the frontier of the science and values discourse.     

The methodological strategies of agroecological research and the values with which they are linked

The characteristic features of some of the methodological strategies adopted in scientific research in agroecology are discussed. They reflect that agroecology, as an approach to scientific research, is inextricably entangled with the other strands of agroecology (farming practice, social movement, political project); and that adopting agroecological strategies, and upholding the values of environmental sustainability, food sovereignty, social justice and democratic participation, mutually reinforce each other. After outlining the kinds of questions that agroecological research addresses so that it can produce knowledge that informs agroecological farming practices and the long term aspiration of agroecological movements to create an alternative agricultural/food system, and then making summary remarks about methodological strategies in general, three characteristic features of some agroecological strategies are introduced and discussed. The paper concludes with comments on the value of agroecological research.
