为了充分彰显职业教育特点,从2010年开始,江苏省中职"单招"色彩专业测试在传统默写的大框架内做了些改变,风格由传统的绘画性写实色彩变为更符合职业教育人才培养需求的设计性创意色彩。于是,中职美术色彩开始了相对应的教学改革。但是,教师已有的学科认识和既定的教学内容成为了阻碍,亟待围绕"从传统写实走向现代创意"这一主线更新重建,有效提升学生的创新能力和创新意识,方能使改革的初衷得以顺利实现。 相似文献

A 9-story concrete-filled steel tubular frame model is used to analyze the response of joints due to sudden column loss. Three different models are developed and compared to study the efficiency and feasibility of simulation, which include substructure model, beam element model and solid element model. The comparison results show that the substructure model has a satisfying capability, calculation efficiency and accuracy to predict the concerned joints as well as the overall framework. Based on the substructure model and a kind of semi-rigid connection for concretefilled square hollow section steel column proposed in this paper, the nonlinear dynamic analyses are conducted by the alternate path method. It is found that the removal of the ground inner column brings high-level joint moments and comparatively low-level axial tension forces. The initial stiffness and transmitted ultimate moment of the semi-rigid connection are the main factors that influence the frame behavior, and their lower limit should be guaranteed to resist collapse. Reduced ultimate moment results in drastic displacement and axial force development, which may bring progressive collapse. The higher initial stiffness ensures that the structure has a stronger capacity to resist progressive collapse. 相似文献

第一,激发兴趣,培养能力．数学活动课是在教师的指导或参与下,学生充分发挥自主性,自己动手动脑进行实践的过程,是以应用数学知识为目的,进行一些手工制作,或安排一些探索性活动的课,它是一种有利于激发学生兴趣、发展学生能力的实践性教学活动． 相似文献

This paper presents the design, analysis and experimental study of a loading system for heavy-duty nodes test based on a large-scale multi-directional in-plane loading device, which has been used in a full-scale heavy-duty support node test. Test loads of the support reached 6 567 kN with multi-directional loading requirements, which outrange the capacity of the available loading devices. Through the reinforcement of a large-scale multi-directional inplane loading device, the innovative design of a self-balanced load transferring device, and other arrangement considerations of the loading system, the test was implemented and the loading capacity of the ring was considerably enlarged. Due to the heavy loading requirements, some checking computations of the ring and the load transferring device outranged the limit of the Chinese national code "Code for Design of Steel Structures (GB 50017—2003)", thus elastic-plastic finite element (FE) analysis was carried out on the two devices, and also the real-time monitoring on the whole loading systems during experiments to ensure test safety. FE analysis and test results show that the loading system worked elastically during experiments. 相似文献
