摘要：以人工智能为代表的前沿技术具有高风险和高投入的特征,在研发过程中会存在“确定的”国家战略和“不确定的”原创探索的矛盾。建立以国家使命目标为导向并充分发挥创新网络效能的创新组织模式,对中国实现科技自立自强具有重要意义。本研究选取美国国家人工智能研究所为案例对象,发现其实现国家导向下的探索研究的机理在于:(1)宏观层面通过部门协调执行顶层战略决策,贯彻国家使命和愿景;(2)中观层面构建“分布式聚合”创新网络,扩大创新主体的参与;(3)微观层面实施行政领导和业界专家等多方主体参与的项目运行机制,将战略引导和自由探索结合。进而总结出平衡国家战略和原创探索的“顶层设计—创新网络—运行机制”的前沿技术组织理论框架,并结合实践提出适合中国的前沿技术创新组织模式,为部署关键共性技术和未来技术研发提供政策启示。

摘要：目的以NEWTOP高速智能纸杯成型机为研究对象,分析纸杯机卷封机构的工作原理,并对其结构进行优化设计与仿真分析,设计出高效、精准的卷封机构。方法通过对卷封传动机构的凸轮进行理论设计与分析,提出凸轮设计的优化方案;采用SolidWorks软件建立三维实体模型,运用运动学仿真软件ADAMS对凸轮机构进行仿真分析。结果凸轮机构的位移、速度和加速度曲线图表明该机构为变速运动,且加速度曲线趋向于正弦加速度运动规律,适合高速转动的凸轮。结论解决了现有卷封机构工作效率低、使用寿命短等问题,同时提高了纸杯成型机的效率。

摘要：In order to reduce the resistance and improve the hydrodynamic performance of a ship, two hull form design methods are proposed based on the potential flow theory and viscous flow theory. The flow fields are meshed using body-fitted mesh and structured grids. The parameters of the hull modification function are the design variables. A three-dimensional modeling method is used to alter the geometry. The Non-Linear Programming(NLP) method is utilized to optimize a David Taylor Model Basin(DTMB) model 5415 ship under the constraints, including the displacement constraint. The optimization results show an effective reduction of the resistance. The two hull form design methods developed in this study can provide technical support and theoretical basis for designing green ships.

摘要：A five-axis serial-parallel kinematic milling machine, the SPKM 165, is introduced. This machine consists of a three-degree of-freedom parallel module and a two-degree-of-freedom serial table. The SPKM 165 is capable of five-face machining. A discussion of the inverse kinematics of the five-axis control is provided. A dimensional synthesis procedure is presented in terms of motion/force transmissibility. Finite-element analysis was used to evaluate the stiffness of a CAD model before the machine was manufactured. Kinematic calibration was implemented to improve the accuracy of the end effector. The results of a calibration experiment are presented. The stiffness of the developed machine was then measured. Milling experiments were conducted, and the test piece showed that the developed machine has satisfactory performance.

摘要：文化养老是当代老年人适应时代发展的新型养老方式。老年游学作为集休闲、旅游、教育于一体的创新型老年教育方式,能有效满足老年大众的精神文化需求,受到老年群体的普遍青睐。结合老年人的身心特征和游学偏好进行游学课程产品的开发,具有重要意义。老年游学课程产品主要包括怀旧型、观光型、增知型、疗养型等四种类型。老年游学课程产品开发可以从以下四个方面加以改进:一是明确产品目标定位,做好游学课程顶层设计;二是评估顾客游学需求,合理开发老年游学课程;三是丰富游学课程产品供给,创新课程实施形式;四是多方收集产品反馈意见,注重游学课程成效。

摘要：Tolerance design, including tolerance analysis and distribution, is an important part of the electronic system’s reli- ability design. The traditional design needs to construct mathematic model of material circuit, which involves large amount of workload and lacks of practicability. This paper discusses the basic theory of electronic system’s reliability tolerance design and presents a new design method based on EDA (Electronic Design Automatic) software. This method has been validated through the application research on reliability tolerance design of the DC hybrid contactor’s control circuit.
