Acta Metallurgica Sinica(English Letters) 1996年第3期9卷 217-222页

By means of Precipitation hardening, a cast copper alloy with high strength and heatresistance named Cu-6Ti-Cr-Al has been developed. This alloy has good castability. After water quenching at 860℃ for 1 h and aging at 450℃ for 4 h, the tensile strength, σ_b, is greater than 890MPa and the compressive strength, σ_(bc), reaches 1300MPa, while the ratio of compression, ε_c, is maintained at 20%. When the environmental temperature is raised to 450℃, the mechanical properties do not show any appreciable loss. These copper alloy castings have been used on the roll sleeves of rubber formers and the journal bearings of sheet mills. The results have shown that the service life of these parts is much longer than that of aluminium bronze and 904alloy castings. In the present work, the microstructure, mechanical properties and strengthening mechanism were investigated.

复杂系统可靠性分析结果的准确性与输入参数精度密切相关。针对包含多源不确定信息的可靠性分析问题,提出了基于贝叶斯最大熵的随机模型修正与参数校准方法。该方法将类型统计信息(例如矩信息、可靠度)转换为约束条件,进而利用不确定性优化求解传统参数估计问题。考虑混合不确定性,引入Wasserstein距离构建似然函数,并利用近似算法提高计算效率。该方法通过增加“熵项”的方式拓展了经典贝叶斯推理的适用范围,可处理多源异构数据与混合不确定性问题。针对多部件航空发动机转子系统,建立了基于survival signature的多态系统可靠性模型,并应用上述方法开展可靠性分析,结果显示本方法较传统方法具有更高精度与更强的稳健性。

Molten salts is a promising medium for heat storage and heat transfer due to their advantages of low cost, low steam pressure, high energy storage density and wide temperature range. In this paper, a new phase change mixture of molten salts with KNO3, NaNO3, ZnCl2, NaF, Na2CO3, NaCl, and MgO as materials has been prepared through a plenty of experiments. The experimental results show that the melting point of some molten salts can be reduced to 202.9°C, and the decomposition temperature can reach 701.3°C. In addition, its thermophysical properties, including specific heat, viscosity and thermal stability, were measured and analyzed. The average specific heat of some molten salts is as high as 2.53 J/（g K）, and the average thermal conductivity is as high as 0.77 W/（m K）. In the 4-day short-term thermal stability test, the fluctuation of each parameter is minimal, and the overall thermal physical property is relatively stable. Compared with the traditional phase change molten salt, the new hybrid molten salt has a significantly lower melting point, a further improvement in the decomposition temperature, specific heat and other comprehensive thermophysical properties, and a better overall economy, which has important application value in heat transfer and energy storage.

当今世界正经历百年未有之大变局,全球性风险频发,现行全球治理体系赤字严重。上海合作组织作为由非西方国家、新兴大国、转型国家组成的新型地区国际组织,在推动全球治理体系变革、践行真正的多边主义方面具有独特作用。中国作为上合组织创始成员国,在该组织提升地区治理能力、积极参与全球治理进程这一重大历史性任务面前责无旁贷:应将上合组织打造成真正多边主义的行动典范;加强成员国间政治互信,发挥上合组织预防性、延伸性合作功能;着力提升上合组织综合实力,夯实多边政治互信及安全合作的物质基础。

欧亚经济联盟作为新型区域经济一体化机制已经客观存在,并对中国及欧亚周边地区产生了实质性的影响.运行五年来,欧亚经济联盟并未实现大的发展,但也未半途夭折.文章通过分析欧亚经济联盟理论基础和运行实践得出:欧亚经济联盟是欧亚地区自身特点与欧洲一体化先进经验的结合体,组建其的重要经济动因是在长期低油价情况下,能够共同拓展经济发展空间,解决本国宏观经济增长乏力的困境.以欧亚经济联盟为机制载体的欧亚一体化更是俄罗斯强国战略下的“引领式一体化”,是俄罗斯面对东西方地缘政治经济压力,为拉紧周边中小国家而推行的“维系式一体化”,也是俄罗斯周边中小国家的“追随式一体化”.欧亚经济联盟在中短期内将继续保持低速前进,从商品共同市场逐步向能源共同市场迈进;从长期看,其一体化发展水平将低于欧盟,但高于东盟和南方共同市场,国际影响力将大于独联体.因此,在百年未有大变局中,面对新生的欧亚经济联盟,中国在欧亚战略选择中应充分认识到:首先,在与发达经济体实现“良性脱钩”的过程中,欧亚经济联盟是可以争取的支持力量,而在处理与其他新兴经济体,尤其与欧亚新兴经济体的关系时,欧亚经济联盟及其主导国俄罗斯是需要战略协作的对象;其次,与对美关系不同,俄罗斯则是中国最重要的战略伙伴,中俄关系是中国大国外交的“压舱石”.中俄关系始终是推动“一带一盟”对接合作,营造良好周边环境的关键点.
