Based on the special physical–chemical characteristics of optical crystal in the field of aeronautics,a new anhydrous based shear-thickening polishing(ASTP)method has been proposed to restrain deliquescence and to improve physical properties for KDP *** ultraprecision polishing of KDP crystal is completed by ASTP.A kind of anhydrous based thickening polishing slurry(ATPS)was proposed in our work,and high-performance rheological properties were determined to achieve the ASTP of KDP crystal.A material removal model of ASTP in KDP machining is established,followed by the verification experiment of the prediction *** maximum error of the predictive model is only 9.8%,which proves the validity of the material removal model for KDP *** polishing experiments were carried out on the polishing platform developed by *** results show that the new polishing method can polish20 mm×20 mm×5 mm KDP crystal and obtain a super-smooth surface with a surface roughness of 1.37 nm and high shape *** surface accuracy of polished KDP crystal reaches up to0.68 k(RMS).The experimental results show that the ASTP is a potential ultra-precision machining method for KDP crystal.

The global trends towards improving fuel efficiency and reducing CO;emissions are the key drivers for lightweight solutions. In sheet metal processing, this can be achieved by the use of materials with a supreme strength-toweight and stiffness-to-weight ratio. Besides monolithic materials such as high-strength or light metals, in particular metal–plastic composite sheets are able to provide outstanding mechanical properties. Thus, the adaption of conventional, wellestablished forming methods for the processing of hybrid sheet metals is a current challenge for the sheet metal working industry. In this work, the planning phase for a conventional sheet metal forming process is studied aiming at the forming of metal–plastic composite sheets. The single process steps like material characterization, FE analysis, tool design and development of robust process parameters are studied in detail and adapted to the specific properties of metal–plastic composites. In material characterization, the model of the hybrid laminate needs to represent not only the mechanical properties of the individual combined materials, but also needs to reflect the behaviour of the interface zone between *** on experience, there is a strong dependency on temperature as well as strain rate. While monolithic materials show a moderate anisotropic behaviour, loads on laminates in different directions generate different strain states and completely different failure modes. During the FE analysis, thermo-mechanic and thermo-dynamic effects influence the temperature distribution within tool and work pieces and subsequently the forming behaviour. During try out and production phase,those additional influencing factors are limiting the process window even more and therefore need to be considered for the design of a robust forming process. A roadmap for sheet metal forming adjusted to metal–plastic composites is presented in this paper.

首先以91μm磨粒杯形铜基金刚石砂轮作为修整器并结合砂轮在线电解修锐技术(ELID,Electrolytic in- process dressing)对151μm磨粒电镀镍基单层金刚石砂轮进行精密高效的修整。在最佳的修整参数下,同时应用测力仪对两个砂轮间磨削力进行监测,并应用共轴光学位移检测系统对砂轮表面状态进行在位监测,151μm砂轮的回转误差被减小至1～2μm范围,同时砂轮上所有金刚石磨粒被修整出平坦表面并拥有恒定的圆周包迹,此时砂轮达到最佳工作状态。然后应用被良好修整的砂轮对光学玻璃BK7进行磨削加工。磨削试验结果和亚表层完整度评价结果表明新开发的大磨粒金刚石砂轮修整技术的可行性,也验证大磨粒金刚石砂轮只要经过精密修整是可以应用于光学玻璃的延展性超精密磨削加工的,并能实现纳米级的表面粗糙度,显示出大磨粒金刚石砂轮在加工难加工材料和硬脆材料中的良好应用前景。

在卡普瓦尔克拉通早太古到早元古的泥质岩和火山岩中,含Al2O3高于20％的岩石广泛分布。这些岩石的富铝性质归因于分解作用,当原始物质含Al2O3量达60％时,它从源岩滤掉并移入溶液中。这些岩石很大部分也显示含K2O达10％的成岩环境,许多情况下,分解作用反应影响没有打乱细微构造的原岩,如在火山玻璃颗粒中的去玻璃化珍珠裂纹口。这些岩石大多数的成因可归因于地面风化时的分解作用,它们代表古土壤。对其它产状而言,在地层上下关系上排除作为古土壤的解释,这种岩石类型的成因归因于熔岩或凝灰岩在热液喷气作用下所产生的水下分解。已经表明,在绿片岩带中富铝的岩石几乎无例外的都是水下形成的,而更年轻的产地都是风化成因的,地质构造的不同引起与此相反的解释。从加拿大地盾、津巴布韦、西澳大利亚、印度和波罗的地盾所记载的相同化学成分的岩石来看,它们显示出这些岩石的保存潜力是很强的,只有进行地层关系的研究,才能作出是否一个特殊产状是风化产物还是水下分解作用产物的结论。

浙江大学文物与博物馆学系联合荷兰阿姆斯特丹艺术大学开展的"参与式博物馆:机遇、挑战与问题"工作坊每一周都安排不同的教学活动。第一周熟悉主题,接下来是参与式展示、参与式征集、参与式研究,最后进行工作坊成果总结与思考。博物馆1.0传统模式是博物馆自己制作展览、自己发布内容和信息,观众只需要被动接受。而现在的博物馆2.0应该是由观众创作和生成内容,并与其他观众和博物馆工作人员进行分享和交流的一个平台。参与式博物馆是一种新的博物馆理念,其核心应该是创造、分享、互动、交流,博物馆是一个观众能够围绕其内容进行创作、分享并成为与他人交流的场所。

Despite advances in forecasting and emergency preparedness, weather related disasters continue to cost many lives, to displace populations and to cause wide-spread damage. Therefore, High Impact Weather Project (HIWeather), a 10-year research project (https://***/en/resources/buHetin/hiweather-10-yearresearch- project), was established in 2016 by WM0 (World Meteorology Organization) WWRP (World Weather Research Program: https://***/pages/prog/arep/wwrp/new/wwrp_new_en. html). HIWeather aimed at achieving dramatic improvements in the effectiveness of weather-related hazard warnings, following recent advancement in numerical weather prediction at km-scale and in disaster risk reduction. The implementation plan was developed under the concept of warning chain, which comprises all components and the connections between to a successful weather-hazards warning: observations, weather forecast, hazard forecast, impact forecast, the generation of warnings and decision making (Fig. 1). A successful warning relies on information produced by the meteorological and related physical sciences, thus its effectiveness of delivery depends on applications of social, behavioral and economic sciences. The workshop of WM0 High Impact Weather Project was held in Beijing during 20-22 November of 2018, attracted a diverse and interdisciplinary group of over 70 scientists from 25 countries in the broad field of physical and social science, during which all elements of the warning chain were discussed critically.

The Kaapvaal Craton in South Africa hosts one of the largest gold placer deposits in the world. Mining in the Witwatersrand Basin here has been the source of about one third to one half of the gold ever produced in the world. Gold was discovered in the Johannesburg area in 1886 and after 120 years of continuous operation, mining is currently approaching depths of 4 000 m. In spite of the challenges and risks that the industry has had to deal with including rock temperature, ventilation and water, one of the most feared hazards in the basin has been the threat from the ongoing occurrence of seismicity and rockbursts. The problem first manifested itself by way of the occurrence of tremors roughly twenty years after the commencement of mining operations. This paper traces the history of the approach to rockbursts and seismicity during the 120 year history of mining in the basin. It portrays a picture of the mining seismicity in terms of monitoring phases, mechanisms and mitigation strategies. The work of research organizations over the years is highlighted with a brief mention of current regulation strategies on the part of the mining inspectorate.

世界上不同国家的许多人都曾为世界石油大会作出过重要贡献，但说到世界石油大会的创始人，则非托马斯·杜赫斯特（thomas Dewhurst)莫属。他是第一任世界石油大会主席。其功绩不仅在于创建了世界石油大会，并建立了大会常设机构秘书处。更为重要的是，托马斯·杜赫斯特先生提出了一个富有远见的创意－世界石油大会唯一的宗旨是促进并促进并扩展石油科学技术的进步,而且相互间的交流不只局限于信息和知识，还应包括各国石油科技专家之间的友谊。世界石油大会不允许存在政治或种族的屏障。托马斯·杜赫斯特曾经为世界石油大会写下这样的哲理：“请永记世界石油大会的宗旨，如有必要，可以将其铸成金字，高悬于云霄。”尽管许多年来，由于石油工业的迅速发展，其科学技术的进步已经大大超出了原有的理念，但托马斯·杜赫斯特先生的这个，即世界石油大会的宗旨，仍然是每次世界石油大会的座右铭。
