Although the toughening of Calcium phosphate(CaP)scaffold by the addition of fiber has been well recognized,integrated mechanical,structural and functional considerations have been neglected in the design and fabrication of CaP scaffold *** emerging 3D printing provides a promising technique to construct CaP scaffold with precise size and elaborate ***,the most challenge is to extrude smoothly the CaP paste containing fibers for frequently-used extrusion-based 3D *** this study,frozen section and chemical dispersant(Pluronic F127,F127)were employed jointly to prepare non-aggregated polylactic-co-glycolic acid(PLGA)*** injectability of CaP pastes with well dispersed PLGA fibers was more than 90%when the content of PLGA fibers was no more than 3 wt%.Meanwhile rheological property of CAP pastes with well dispersed fibers showed shear thinning,which were both beneficial to extrude CaP paste with well dispersed fibers for 3D ***,these CaP scaffolds showed ductile fracture behavior due to the pullout and bridging effect of PLGA *** cell proliferation and alkaline phosphatase(ALP)activity indicated that 3D printed CAP scaffold containing PLGA fibers possesses excellent biocompatibility and facilitate osteogenic differentiation ***,it was feasible to print CaP pastes with well dispersed PLGA fibers to construct toughening CaP scaffolds with the higher shape fidelity and complex structures,which had significant clinical potentials in osteoanagenesis due to their higher toughness and excellent biocompatibility.

"跨太平洋伙伴关系"谈判是美国实施所谓"再平衡"战略的重要组成部分。这一多边谈判架构能否持续下去,取决于其是否能够获得足够的发展动力。本文从微观角度出发、从内外两方面探讨了这一多边谈判的发展动力问题。从内部看,由于在美国的实力和意愿之间存在巨大的反差,谈判本身面临着内部动力不足的问题。这决定了美国无法采取"以经济换安全"的传统做法来推动谈判的顺利进行。从外部看,经济效益并不能充分解释谈判的持续进行,区域贸易谈判的"多米诺骨牌"效应难以产生充分的前行动力。然而,利用当前亚太地区一些国家对中国的崛起产生疑惧情绪,进而希望借助美国平衡中国的心理,美国得以顺利推进TPP谈判。经济与安全的密切互动为美国推动TPP谈判提供了较强的发展动力。面对TPP谈判带来的国际形势新变化,中国应该有的放矢,通过积极应对来化解TPP谈判带来的挑战。

跨境电子收付报告能够为货币跨境流动的反洗钱监管提供理想的解决方案。跨境电子收付报告的类型化分析和差异性分析,能够满足金融监管部门对货币跨境流动的反洗钱监管需求,也可以为司法部门打击跨境经济犯罪提供高效的侦查、取证方式。本文认为,目前我国构建跨境电子收付报告制度的最大阻力来自于成本因素,但是可以通过实行批量文件处理、坚持最小信息量原则以及设立触发机制来解决,从而有效提高我国货币跨境流动的反洗钱监管效率。

针对理想复飞轨迹已知条件下的舰载机自动复飞控制问题,提出一种基于偏差模型的动态面控制(DM-DSC)算法。基于Radau伪谱法给出了舰载机着舰的最优复飞轨迹;根据得到的最优复飞轨迹及其所对应的控制方案,分别给出了速度子系统和高度子系统的偏差控制模型和反演(Backstepping)控制器,并通过引入动态面结构来获得虚拟控制量的微分信号,避免了Backstepping控制律求解过程中的“微分膨胀”问题;考虑到气动参数的不确定性及舰尾流场的干扰,采用线性扩张状态观测器(LESO)对控制模型中的干扰项进行估计和补偿,并设计抗饱和辅助系统来抑制控制饱和的不利影响;最后,基于Lyapunov方法证明闭环系统信号的有界性。仿真结果表明:所提算法具有良好的控制性能。
