浙江省BPO产业运作模式的选择

业务流程外包（BPO）产业是目前国内外竞争的焦点之一,如何选择适合自身的运作模式越来越受到企业的重视。文章从三个角度对国内外BPO运作模式进行了归纳总结,并结合浙江省实际情况,分别对发包方和承包方的运作模式提出建议,认为有多年外贸经验的企业可以直接承揽海外公司的外包业务;对软件行业而言,可以考虑成立外包联盟;实力较强的外包企业可通过并购模式,扩大业务范围。就浙江省BPO产业整体而言,只有打造区域品牌,增强核心竞争力,加强与国内其他地区的交流与合作,才能进一步发展壮大。     

用于航天器贮箱的复合材料层合板低速冲击损伤及其渗漏规律研究

得益于优异的力学性能和减质优势,贮箱复合材料化已成为新一代航天器的重要特征之一,而复合材料贮箱的冲击后渗漏问题须要重点关注。针对一种用于航天器贮箱的含表层机织布复合材料层合板,通过依次开展低速冲击试验、C扫描损伤检测和氦质谱渗漏检测,获取不同能量冲击后层合板的内部分层损伤和渗漏率,并对比分析了机织布分别置于冲击侧和背侧时层合板的渗漏规律。结果表明,将机织布层置于冲击背侧时,层合板的冲击渗漏门槛值显著提高,且发生渗漏时出现目视可见损伤。

Multi-scale design and optimization for solid-lattice hybrid structures and their application to aerospace vehicle components

By integrating topology optimization and lattice-based optimization, a novel multi-scale design method is proposed to create solid-lattice hybrid structures and thus to improve the mechanical performance as well as reduce the structural weight. To achieve this purpose, a two-step procedure is developed to design and optimize the innovative structures. Initially, the classical topology optimization is utilized to find the optimal material layout and primary load carrying paths. Afterwards, the solid-lattice hybrid structures are reconstructed using the finite element mesh based modeling method. And lattice-based optimization is performed to obtain the optimal cross-section area of the lattice structures. Finally, two typical aerospace structures are optimized to demonstrate the effectiveness of the proposed optimization framework. The numerical results are quite encouraging since the solid-lattice hybrid structures obtained by the presented approach show remarkably improved performance when compared with traditional designs.     

Recent active thermal management technologies for the development of energy-optimized aerospace vehicles in China

Recently, the development of modern vehicles has brought about aggressive integration and miniaturization of on-board electrical and electronic devices. It will lead to exponential growth in both the overall waste heat and heat flux to be dissipated to maintain the devices within a safe temperature range. However, both the total heat sinks aboard and the cooling capacity of currently utilized thermal control strategy are severely limited, which threatens the lifetime of the on-board equipment and even the entire flight system and shrink the vehicle’s flight time and range. Facing these thermal challenges, the USA proposed the program of “INVENT” to maximize utilities of the available heat sinks and enhance the cooling ability of thermal control strategies. Following the efforts done by the USA researchers, scientists in China fought their ways to develop thermal management technologies for Chinese advanced energy-optimized airplanes and spacecraft. This paper elaborates the available on-board heat sinks and aerospace thermal management systems using both active and passive technologies not confined to the technology in China. Subsequently, active thermal management technologies in China including fuel thermal management system, environment control system, non-fuel liquid cooling strategy are reviewed. At last, space thermal control technologies used in Chinese Space Station and Chang’e-3 and to be used in Chang’e-5 are introduced. Key issues to be solved are also identified, which could facilitate the development of aerospace thermal control techniques across the world.

中国文化产业进入东盟市场的可行性

中国与东盟各国的人文背景相通,民族语言互通,在宗教信仰上相同或相似,生计方式互补,文学艺术相互渗透.若借助上述有利的人文条件,可以顺利地将中国文化产业推向东南亚各国,获得可观的经济效益.困难之处在于上述各国大多存在着较为尖锐的民族对立,政治体制与宗教政策差异较大,展开此类商贸活动,很难获得各国官方的认可和全力支持.此外,上述各国对中国侨民的政策差异甚大,一些国家对华侨抱有偏见.因此,最好采用民间文化交流方式或通过私营企业渠道推进我国文化产业发展.
