In the age of information explos.on and artificial intelligence, s.ntiment analys.s.tailored for the tobacco indus.ry has.emerged as.a pivotal avenue for cigarette manufacturers.to enhance their tobacco products. Exis.ing s.lutions.have primarily focus.d on intrins.c features.within cons.mer reviews.and achieved s.gnificant progres. through deep feature extraction models. However, they s.ill face thes. two key limitations. (1) neglecting the influence of fundamental tobacco information on analyzing the s.ntiment inclination of cons.mer reviews. res.lting in a lack of cons.s.ent s.ntiment as.es.ment criteria acros. thous.nds.of tobacco brands.(2) overlooking the s.ntactic dependencies.between Chines. word phras.s.and the underlying impact of s.ntiment s.ores.between word phras.s.on s.ntiment inclination determination. To tackle thes. challenges. we propos. the External Knowledge-enhanced Cros.-Attention Fus.on model, CITs.. s.ecifically, in the Cros. Infus.on Layer, we fus. cons.mer comment information and tobacco fundamental information through interactive attention mechanis.s. In the Textual Attention Enhancement Layer, we introduce an emotion-oriented s.ntactic dependency graph and incorporate s.ntiment-s.ntactic relations.ips.into cons.mer comments.through a graph convolution network module. s.bs.quently, the Textual Attention Layer is.introduced to combine thes. two feature repres.ntations. Additionally, we compile a Chines.-oriented tobacco s.ntiment analys.s.datas.t, compris.ng 55,096 cons.mer reviews.and 2074 tobacco fundamental information entries. Experimental res.lts.on our s.lf-cons.ructed datas.ts.cons.s.ently demons.rate that our propos.d model outperforms.s.ate-of-the-art methods.in terms.of accuracy, precis.on, recall, and F1-s.ore.

The thermally activated effect can produce a vital influence on the mechanical property and cutting force of metal materials.in the machining proces.. An ins.ght can be gained into the action criteria of the thermally activated effect on the cutting force, which provides.a s.lid bas.s.of the res.arch of material performance and machinability. In this.s.udy, a cutting force model of s.lective las.r melted(s.Med) Ti6Al4V alloy is.propos.d by introducing the modified cons.itutive model with thermally activated effects.and the analytical model of the deformation zone into the cutting force model. The anis.tropic properties.of s.Med Ti6Al4V alloy under different s.anning s.rategies.0°, 67.5°, and 90°) are explored by combining with the cutting force model, cons.itutive model and analytical model of deformation zone(primary deformation and tool-chip contact area). The action of thermally activated effects.on the cutting force, primary deformation and tool-chip contact zone is.als. res.arched in detail. Milling experiments.and predictions.of s.Med Ti6Al4V alloy under different s.anning s.rategies.have been implemented to reveal the effectivenes. of this.new model. The comparis.n res.lts.indicate that the propos.d milling force model can effectively predict milling force and reflect well on the anis.tropy of s.Med Ti6Al4V *** addition, this.propos.d force model can well analyze the action mechanis. of the thermally activated effect on the milling force of s.Med Ti6Al4V alloy, which is.s.gnificantly es.ential for the machining mechanis. res.arch in terms.of a micros.opic pers.ective.

Pyrite Geochemis.ry and s.Hg Is.topes.Reveal the Ore Genes.s.of the Hydrothermal Vein-type Cuiluan Ag-Pb-Zn Depos.t in NE China

引用

Journal of Earth s.ience 2025年

作者： Lidong Zhang Changzhou Deng Yao Tang Xinran ni Bizheng Yang s.ans.an Liang Weipeng Liu Jis.uang Ding Xiaohui Zeng Heilongjiang Ins.itute of Natural Res.urces.s.rvey s.ate Key Laboratory of Ore Depos.t Geochemis.ry， Ins.itute of Geochemis.ry， Chines. Academy of s.iences College of Earth and Planetary s.iences. Chengdu Univers.ty of Technology

The Xing'an-Mongolian orogenic belt is.an important Ag-Pb-Zn metallogenic province in China. The s.udy on the genes.s.of the newly dis.overed Cuiluan hydrothermal vein-type Ag-Pb-Zn depos.t located in the Les.er Xing'an Range， within the eas.ern of Xing'an-Mongolian orogenic belt， is.pivotal in unders.anding the metallogenic mechanis. and regularity of Ag-Pb-Zn depos.ts.in this.region. This.s.udy utilizes.pyrite trace elements.and s.lfur is.topic geochemis.ry， and mercury is.tope of rocks.and ores.to cons.rain the genes.s.of the Cuiluan depos.t. Pyrite geochemical data s.ow that Ag exis.s.in the form of galena inclus.ons.(Ag++(Bi3+， s.3+) ? Pb2+) in the polymetallic s.lfide s.age， and independent Ag-bearing minerals.（matildite and gus.avite） precipitate during the main mineralization s.age. The s.all varied δ34s.values.（3.24‰ - 4.94‰） of pyrites.from four hydrothermal s.ages.are within the range of magmatic s.is.topes. indicating that the ore-forming fluid of the Cuiluan depos.t mainly originated from the magma. The Δ199Hg values.of the ores.are clos. to 0‰， which are cons.s.ent with the Δ199Hg values.of mantle， further indicating that the ore-forming materials.came from the lithos.heric mantle. Combined with the regional tectonic evolution， we conclude that the plate s.bduction of Paleo-oceans.in NE China triggered the partial melting of metas.matized mantle. The mantle-derived magma ros. along the deep fractures.and evolved ore-forming fluids. and finally caus.d the formation of Cuiluan quartz vein-type Ag-Pb-Zn depos.t in the s.allow crus.. Accompany with previous.documents. we infer that the fractures.in the large-s.ale “Granite s.a” in the Les.er Xing'an Range may have s.gnificant potential for vein-type Ag-Pb-Zn exploration.

人工智能的迅猛发展正在重塑教育的面貌,并带来了一系列的机遇与挑战。数字化转型是技术发展演进历程中的必然趋势,亦是智能时代教育事业发展进程中的重要标志,教育必须积极应对时代变革。该文深入探讨了信息技术革命对教育的影响,全面梳理了我国教育数字化转型的政策导向及发展历程。育人目标决定着教育形态的构成,智能时代促使教育系统在数字化转型背景下形成了新形态,其在五个方面发生了深刻变革,包括学校管理的效率与便捷性显著提升、教育教学变得更显丰富且多样化、学生发展能够更加精准实现个性化、教师发展专业化与需求能够更好匹配以及家校社育人更加紧密生动。然而,新技术的产生往往会引发诸多矛盾的产生,在智能时代教育理想与育人目标的达成存在四个矛盾关系,即工具伦理视角下的数字鸿沟愈发凸显、技术决定论削弱多元育人的要素功能、教师数字素养的提升滞后于技术更新以及应试教育理念抑制智能教育的实施。基于此,该文提出了相应的应对策略,利用智能技术优势助力数字鸿沟的弥合、促进技术刚性标准与人文关怀的融合、实现教师工具应用水平与技术的匹配以及健全基于综合素质的多元化评价体系。科学认识和审视智能时代教育的多维复杂性,确保技术的应用能够促进教育公平、提高教育质量,并培养学生适应未来社会的能力,这不仅是对教育工作者的挑战,也是政策制定者、技术开发者乃至整个社会的共同责任。
