Linear Free Energy Relationships in Extraction of Rare Earths by Acidic Organophosphorus Extractants

The correlation relationships of apparent extraction equilibrium constant (1gK(ex)) with the electronic effect parameter( Sigma sigma(Phi)) and the steric effect parameter ( Sigma upsilon ) of the substituents in extractant molecules are investigated by linear regression analysis in the extraction of rare earths by various classes and structures of monoacidic organophosphorus extractants. The results indicate that in Linear free energy relationship formula 1gK(ex) = rho Sigma sigma(Phi) + psi Sigma upsilon + h generally follows for this kind of extraction systems. Accordingly, the quantitative structure-behaviour relationships of extractants are discussed. These relationships can be preliminarily applied to predict the 1gK(ex) values of rare earth extraction with definite structures of this class of extractants, and thus can provide some directions for the design of new RE extractants.

基于Google Earth软件建立曲流河地质知识库

在对密井网解剖、露头解剖、现代沉积解剖、沉积模拟实验等建立地质知识库方法优缺点分析基础上,利用Google Earth软件测量了一系列曲流河道的基础数据,结合"将今论古"思想,提出了基于Google Earth软件建立曲流河地质知识库的方法。首先,分析了已有方法的优缺点。其次,介绍了Google Earth软件测量曲流河道的方法步骤,并测量了不同地区不同曲率的河道宽度、点坝长度及弧长,得到了一系列测量数据,建立了测量数据表,并结合已有经验公式与测量数据拟合得到的公式综合分析。结果表明,不同环境中曲流河的河道宽度和点坝长度具不同的相关关系,曲流河的地质知识库不能按统一标准考虑。在不同曲率情况下,河道宽度和点坝长度之间的相关关系亦不同,且随着曲率的减少,其相关关系减弱,反映出点坝的发育程度受河流弯曲程度控制。最后,建议采用建立地质模式库的思想建立定量化曲流河地质知识库,用于对储层建模进行有效约束。

基于Google Earth Engine的湖泊水位与水体面积关系研究

对于传统的湖泊水位-面积关系模型研究,长时间序列遥感影像水体提取存在数据下载和处理繁琐、大量使用专业软件和人工干预多等问题,研究过程耗时长、效率低.基于Google Earth Engine,对2002年至2016年长时间序列Landsat影像数据进行预处理,利用NDWI提取东洞庭湖水体范围并计算水域面积,结合城陵矶水文站日水位数据,设计水位加权平均法、阈值法和单点水位法比较并确定影像对应的最优水位,建立水位-水体面积关系曲线.研究结果表明:(1)东洞庭湖水域范围随季节变化大,面积在7~9月最大,在1~3月最小;(2)利用阈值法计算最优水位的精度(R^(2)=0.9628)优于加权平均水位法(R^(2)=0.8322)和单点水位法(R^(2)=0.9457);(3)五次多项式模型建立水位-面积关系曲线拟合精度最高(R2=0.9628).

Spatial coupling relationships of gas hydrate formation in the Tibetan Plateau

At present, gas hydrates are known to occur in continental high latitude permafrost regions and deep sea sediments. For middle latitude permafrost regions of the Tibetan Plateau, further research is required to ascertain its potential development of gas hydrates. This paper reviewed pertinent literature on gas hydrates in the Tibetan Plateau. Both geological and ge- ographical data are synthesized to reveal the relationship between gas hydrate formation and petroleum geological evo- lution, Plateau uplift, formation of permafrost, and glacial processes. Previous studies indicate that numerous residual basins in the Plateau have been formed by original sedimentary basins accompanied by rapid uplift of the Plateau. Ex- tensive marine Mesozoic hydrocarbon source rocks in these basins could provide rich sources of materials forming gas hydrates in permafrost. Primary hydrocarbon-generating period in the Plateau is from late Jurassic to early Cretaceous, while secondary hydrocarbon generation, regionally or locally, occurs mainly in the Paleogene. Before rapid uplift of the Plateau, oil-gas reservoirs were continuously destroyed and assembled to form new reservoirs due to structural and thermal dynamics, forcing hydrocarbon migration. Since 3.4 Ma B.P., the Plateau has undergone strong uplift and extensive gla- ciation, periglacier processes prevailed, hydrocarbon gas again migrated, and free gas beneath ice sheets within sedi- mentary materials interacted with water, generating gas hydrates which were finally preserved under a cap formed by frozen layers through rapid cooling in the Plateau. Taken as a whole, it can be safely concluded that there is great temporal and spatial coupling relationships between evolution of the Tibetan Plateau and generation of gas hydrates.

On the Relationship between Atmospheric Carbon Dioxide and Global Temperature

The study of dynamic relationships between the atmospheric carbon dioxide and the Earth’s global temperature in the current changing climate supported the notion that the trend in the global temperature followed the trend in the atmospheric CO2 before the climate hiatus that started in the beginning of the 21st century. During the hiatus period, the heat trapped by the atmospheric CO2 is going mostly to the ocean. This conclusion is supported by comparison of the CO2 trend with the trend in the ocean heat content. The phase relationships between the CO2 and temperature are more complicated after the removal of the trends. The phase relationships are chaotic on time scales shorter than the annual time scale. During 1986-2008, the atmospheric CO2 changed in an-ti-phase with the global temperature. The phase relationship reversed in 1979 and after 2010. The atmospheric CO2 was in-phase with the global temperature on the El Nino time scale (2.3 - 7 years) except during very strong El Nino years in 1991-1999 when CO2 led the global temperature.

The Relationship between Men and Nature Reflected by the Conflict be tween Captain Ahab and Moby Dick

"Moby Dick"is an in-depth spiritual exploration about beliefs,religion,fate and nature with multi-layered meanings.This novel is based on a whale-hunting adventure,which turns out to be actually a vengeance-seeking voyage.The plot is very simple,yet the meaning behind it is far from simple.Applying symbolism,Melville depicts a hostile relationship between men and nature,which is spotlighted by the conflict between Captain Ahab and Moby Dick.This thesis deals with the relationship between men and nature as presented in the novel,the symbolic meaning that Melville intends to convey and his attitude towards the ideal relationship between men and nature.

The Humorous but Coherent Characterization of the Little Man in "The Egg", "The Secret Life of Walter Mitty" and "Shiloh"

Though with different times and backgrounds,these three masterpieces-"The Egg","The Secret Life of Walter Mitty"and"Shiloh"all humorously characterize the same type protagonist-the"little man".Penetrating the humorous characterization,the three works on the one hand present the rational question of the mainstream society and the serious critique of the dominant forces,on the other hand,they also offer the humanistic affirm and concern of the marginalized little man.Thus,bundle these three master pieces together,this paper makes an effort to analyze the humorous characterization of the little man;the comic gender relationships so as to figure out the coherent thematic significance as well as the philosophical seriousness of humor in these three masterpieces.

中国古代儒家伦理思想中的道德空间智慧探论

道德空间是指个体以道德规范来调节自我身心,自我与他人、社会,以及自我与自然的关系,从而建构起来的价值空间。它体现为个体在道德关系场域中的得居其位和与外界的共生、共处状态。在以往伦理学理论体系中,道德空间并非显性范畴,但这并不能表明传统伦理思想体系中就没有这方面的思想智慧。中国古代儒家伦理思想就隐藏着丰富的个体道德空间智慧:一是“养浩然之气”和“慎独”学说蕴含的个体身心维度的道德空间智慧,养浩然之气意味着个体恰当安置身心于身心关系场域,慎独意味着个体自我内求道德并以合德方式谨慎把握身心关系,因此它们都是个体身心维度的道德空间建构;二是“仁”“礼”统一学说蕴含的个体与他人、社会维度的道德空间智慧,仁指爱人利人、将心比心、推己及人以形成相互仁爱的人际关系,礼乃仁之具体行为规范和行为模式,以及人们循礼而为所形成的礼和秩序,仁爱关系、礼和秩序都是个体人际维度的道德空间架构;三是“天人合一”学说蕴含的个体与自然维度的道德空间智慧,其中天即自然界,人是作为主体的存在,天人合一意味着天人合德,而天人合德即意味着人以道德规范来协调自我与自然的关系,与自然共生、共处,从而展现出人与自然维度的道德空间意蕴。这些道德空间思想智慧对于人们协调自我身心关系,平衡自我与他人、自我与社会的关系,调节自我与自然的关系,从而实现人与自然的和谐共生,具有重要意义和启迪价值。

生成式人工智能沉迷的法律规制:动因及对策

生成式人工智能的蓬勃兴起为经济社会发展注入了新动能,正在深刻改变人们的生产生活方式,同时也容易导致人工智能沉迷问题。这不仅是个体层面的问题,更涉及人的思维自由、行为自由、人的主体地位等更深层次的问题。当前在防范方面还存在着对象范围过窄、监管方法不当、防沉迷领域局限以及防范义务不明确且手段单一等问题。应当从法律层面对生成式人工智能的沉迷问题进行规制,明确生成式人工智能提供者的防沉迷义务,转变监管方法,加大监管力度,建立生成式人工智能沉迷防范体系,发挥多元主体协同共治,确保生成式人工智能的使用符合人类整体利益。

广义道德论:当代科技道德的重塑

当代科技既超现实又反现实,在建构世界的同时又对真实世界实现了“降维打击”。探讨当代科技发展趋势如人工智能、生物医学、基因编辑、量子科技等,需要明确其中蕴含的当代性。所谓当代科技发展之“发展”有双关深意:既生成了新兴技术的道德问题本身,又生成了可解方案——广义道德论。新技术的溢出突破道德解释的理论极限,需要创设一种能够将“包容性”和“适应性”统合起来的新伦理解释框架。新的伦理解释框架是递归的科技道德问题与道德设计创造性的变量函数值,亦是当代科技发展中新的人与技术关系方程式。

增强还是替代:人工智能与人类智能关系的哲学反思

人工智能哲学的核心论争是考察人工智能与人类智能的紧张关系与有机张力。人工智能是一个比照与关联了合成智能、计算智能与增强智能的概念,其建构目标是智能主体,底层逻辑是大数据,运行关键是算法。人工智能的发展形态蕴含着从弱人工智能到强人工智能或通用人工智能的可能路向,甚至不排除在未来演化出超级智能的形态。人工智能与人类智能之间存在着内在的紧张关系:人工智能或以温和的方式实现对人类智能的模拟与增强,或以激进的方式去超越与替代人类智能。人类未来既需要认真对待与重视人工智能,也需要为其构建平等合理的伦理原则。

无人经济趋势下的未来城市空间创新与规划应对

聚焦无人化趋势下的城市新型人地关系,结合无人化趋势带来的业态创新和就业模式变化,推演未来可能出现的无人化场景及其对规划技术提出的新挑战,由此得出如下新趋势并提出相应的规划应对设想:在无人化趋势下,以人定地的空间规模预测方式的适用性会降低,需要在系统考虑机器换人对各类用地影响的基础上确定城镇空间发展规模;无人化生产和劳动力替代将在一定程度上重构现有的产城空间格局,未来需要加强对无人化产业空间的学术研究和规划技术研究;未来城市会出现大量“人—机”共存交互的空间场景并产生相应的治理难题,急需从时空行为活动导控方面探索提升建成空间利用效率的规划新理论和新方法。
