An ITER torus cryo-pump housing （TCPH）, which encloses a torus cryo-pump, is connected to a vacuum vessel （VV） by a set of associated double bellows. There are complicated loads due to two different operating states （pumping and regeneration） and foreseeable accidents with the cryo-pump. This paper describes a thermal-structural coupled analysis of the present TCPH according to tho allowatfle stress criteria of RCC-MR, in which the worst cases and outcomes of various load combinations are obtained. Meanwhile, optimization of the structure has been carried oul, to obtain positive analysis results and an adequate safety margin.

The ITER equatorial thermal shield is located inside the cryostat and outside the vacuum vessel, and its purpose is to provide a thermal shield from hot components to the superconducting magnets. Electromagnetic analysis of the equatorial thermal shield was performed using the ANSYS code, because electromagnetic load was one of the main loads. The 40 sector finite element model was established including the vacuum vessel, equatorial thermal shield, and superconducting magnets. The main purpose of this analysis was to investigate the eddy current and electromagnetic force in the equatorial thermal shield during plasma disruption. Stress analysis was implemented under the electromagnetic load. The results show that the equatorial thermal shield can accommodate the calculated electromagnetic loads.

ITER edge localized mode （ELM） coils are important components of the in-vessel coils （IVCs） and they are designed for mitigating or suppressing ELMs. The coils located on the vacuum vessel （VV） and behind the blanket are subjected to high temperature due to the nuclear heat from the plasma, the Ohmic heat induced by the working current and the thermal radiation from the environment. The water serves as coolant to remove the heat deposited into the coils. Based on the results of nuclear analysis, the thermal-hydraulic analysis is performed for the preliminary design of upper ELM coils using a rapid evaluation method based on 1D treatment. The thermal-hydraulic design and operating parameters including the water flow velocity are optimized. It is found that the rapid evaluation method based on 1D treatment is feasible and reliable. According to the rapid analysis method, the thermal hydraulic parameters of two water flow schemes are computed and proved similar to each other, providing an effective basis for the coil design. Finally, considering jointly the pressure drop requirement and the cooling capacity, the flow velocity is optimized to 5 m/s.

推动经济社会发展绿色化、低碳化是实现经济高质量发展的关键环节.当前,在政府部门提供政策支持的基础上,单个企业的绿色投资意愿仍然不高,这导致宏观经济高质量发展需求与微观企业绿色投资不足的现实矛盾愈发凸显.本文试图从“同群效应”来探索这一矛盾的解决之道,或许可以为提升企业绿色投资意愿提供新的思路.基于此,本文以中国沪深A股上市公司为样本,对上市公司绿色投资行业同群效应的存在性、作用机制以及经济后果展开研究.研究发现:企业绿色投资存在显著的同群效应;机制检验表明企业绿色投资同群效应存在学习机制与压力机制,即同行业的跟随者会更愿意向领导者学习,外部压力更大时企业绿色投资同群效应更为明显;进一步分析表明,企业绿色投资同群效应实现了企业生产的降本增效和公司价值的提升.本文的研究结论不仅有助于厘清企业实施绿色投资的真实动因,也为行业绿色投资联动和政府相关部门政策制定提供有力依据.

International thermonuclear experimental reactor （ITER） edge localized mode （ELM） coils are used to mitigate or suppress ELMs. The location of the coils in the vacuum vessel and behind the blankets exposes them to high radiation levels and high temperatures. The feeders provide the power and cooling water for ELM coils. They are located in the chinmey ports and experience lower radiation and temperature levels. These coils and feeders work in a high magnetic field environment and are subjected to alternating electromagnetic force due to the interaction between high magnetic field and alternating current （AC） current in the coils. They are also subjected to thermal stresses due to thermal expansion. Using the ITER upper ELM coil and feeder as an example, mechanical analyses are performed to verify and optimize the updated design to enhance their structural performance. The results show that the conductor, jacket and bracket can meet the static, fatigue and crack threshold criteria. The optimization indicates that adding chamfers to the bracket can reduce the high stress of the bracket, and removing two rails can reduce the peak reaction force on the two rails arising from thermal expansion.

战国前后,随气化宇宙论的逐渐成型,“风气”一词作为天象的标记诞生了。先秦到汉代,“风气”在气化宇宙论中因与时空秩序关联而屡屡出现于当时的知识生产活动中,形成了风气/时空—生成物的关系模式,词与物是统一的;中古时期,“风气”成为人物品藻与艺术品鉴的审美用语,词、物分离,成为一种隐喻,而风气/空间—人的关系是其原型;宋代以后,风气—四时的关系模式被扩展为风气—时代的关系,使其由自然时间中的天文现象变为人文时间中的历史与社会现象,“风气”一词也成为重要的人文概念,构筑起一条富有特色的历史解释路径。
