针对材料表面余量精准去除问题,提出了一种基于遗传算法的打磨机器人去除量工艺参数优化方法。首先,以Preston方程和赫兹弹性接触理论为理论基础,建立去除量与工艺参数模型;其次,基于遗传算法以最小去除量误差值作为算法的优化目标对打磨工艺参数求最优解;最后,搭建打磨机器人系统进行优化前后的打磨对比实验验证。结果表明,在去除量值10μm~60μm范围内,该方法相较同类方法的材料去除量平均相对误差ε_(r)了降低13%左右,验证了该优化方法对材料表面余量去除的有效性。

近年来,随着进口牛羊肉价格持续走低,我国牛羊肉产业发展面临产能过剩、价格波动大、饲草成本高等挑战,亟须探索牛羊肉产业发展新路径。加快推进牛羊肉产业转型升级,数字赋能牛羊肉供应链绿色转型是一条可行路径。根据资源编排理论,数字化演进过程包括建构数字基础驱动绿色标准化、捆绑数字要素驱动绿色能力化和撬动数字边界驱动绿色品牌化。经过多年发展,内蒙古牛羊肉供应链虽然具备一定的数字化绿色转型基础,但是仍然存在数字技术应用水平不高、技术创新能力支撑不足、龙头企业带动作用不强、产业链整合与协同不佳、品牌保护与市场推广困难等制约瓶颈。应进一步强化政府推动、创新驱动、全链拉动和品牌带动,通过数字赋能促进内蒙古牛羊肉供应链尽快实现绿色转型。

In this note, we give a necessary and sufficient condition for viability property of diffusion processes with jumps on closed submanifolds of Rm. Our result is the system is viable in a closed submanifold K iff the coefficients are tangent to K along K if the equation is in the sense of stratonovich integral and the solution jumps from K to K.

日常生活是人们所熟知和惯常的生存活动,但琐碎的日常生活常常蕴含着社会系统最本质的规律,居民日常生活的变迁表征着社会的发展变化。以我国古镇旅游发展的先行者周庄古镇为案例地,对旅游发展背景下周庄古镇社区居民日常生活的变迁展开历时性研究具有典型意义。研究发现:在旅游业快速发展的背景下,周庄古镇居民的日常生活以及社会关系经历了较为剧烈而集中的演化变迁。从前旅游阶段的同质化熟人社会到旅游起步阶段的居民居住空间和生计模式转变,业缘交往发展;再到旅游发展阶段的社会交往商业化;最终进入旅游成熟阶段,居民构成异质化、多群体聚居、以旅游业为纽带的全新社会关系诞生。在此过程中,旅游与非旅游居民群体的居住空间分异与交往隔离逐渐凸显,未来可以通过规划和市场的力量引导社区空间布局,推动旅游社区多居民群体的群内与群际交往,提高旅游社区居民生活质量,进而实现旅游社区可持续发展与居民追求美好生活目标的统一。

Rare Metals 2015年第1期34卷 28-33页

作者： hong-Jie Luo Hao Lin Pei-hong Chen guang-Chun Yao School of Materials and Metallurgy Northeastern University Engineering Technology Research Centre of Ministry of Education for Materials Advanced Preparation

Titanium hydride attracts more attention as foaming agent in the fabrication of cellular metal materials. In order to meet most aluminum casting alloy＇s melting properties, the heat treatment processes for Till2 particles were investigated in a rotating device. In the present work, the most two important dynamic parameters, the treating temperature and oxidation interval, were taken under consideration. The decomposition behavior of titanium hydride was measured by differential scanning calorimetry （DSC） and the residual hydrogen content, morphologies and phase conversion were also characterized by hydrogen determinator, scanning electron microscopy （SEM）, and X-ray diffractometer （XRD）, respectively. The results show that the effect of temperature on the formation of oxidation film and decomposition behavior of Till2 is more significant than that of oxidation time. The onset temper- ature and peak value of Till2 decomposition shift from left to right through elevating temperature and extending time. Heat treatment process for Till2 at 500 ℃ between 1 and 5 h in air is favorable for preparing aluminum foam.
