- Standard guide for designing and conducting visual experiments
设计和操纵可视实验标准指南 - The visual experiments also involved manipulated faces and facial features . in this case , observers would focus on a black dot . to the dot ' s right were lips that were fat or thin , or smiling or frowning
同样地，在第二组试验中，参与者也被要求把注意力集中在一个黑点上，黑点右边是或薄或厚或微笑或生气的嘴唇，而黑点左边是一整张面孔。 - According to the modern education theory , we should adopt the following tactics in teaching the concept of chemistry : 1 . use the vivid visual image to let the students gain the knowledge of the concept ; 2 . create the atmosphere and let the students take part in the formation of the concept of chemistry ; 3 . revise the old knowledge while learning the new one to realize the assimilation of concept ; 4 . proceed step by step , lead the students deepen and develop the concept ; 5 . give prominence to the understanding of the key words of the concept , get deeper understanding ; 6 . pay attention to the relation between the concepts ; 7 . optimize the study strategy and enhance the cognition standard , i . e . in the teaching of the concept of chemistry , we must pay great attention to the usage of various kinds of teaching method , including visual experiment , visual language and cai courseware , in order to help the students to understand the concept ; use the question to stimulate students " thoughts , give free rein to students " corpus , and let the students take part in the teaching process actively ; guide the students to remember new concepts and the help of their old knowledge ; pay attention to the levels of the concept , deepen and develop the concept continuously , use various ways to strengthen the meaning of the key words , help the students to master the concepts connotation , and give a clear extension , guide the students to found the concept system
也就是说，在化学概念的教学中，要注意充分运用各种直观教学手段，包括实验直观、语言直观和cai课件直观，帮助学生理解概念；注意运用问题启动学生思维，发挥学生的主体性，使学生积极参与教学过程；要指导学生利用原有认知结构中适当的概念图式来学习新概念；注意概念教学的层次性，不断深化和发展概念；注意通过各种方式强化概念中关键字、词的意义，帮助学生准确把握概念的内涵，清晰界定概念的外延；注意引导学生在应用中建立概念系统，形成合理的概念结构。同时在概念教学中还要注重学习方法的传授和学习策略的形成，进行适当的元认知训练，优化学生的学习策略，提高其元认知水平。根据化学概念的教学策略，化学概念的基本教学程序为:创设问题情境，引入概念;组织问题解决，建立概念;引导知识整理，概念系统化;指导练习应用，概念具体化。 - Abstract : visual experiment was carried out for the enhanced boiling heat transfer in evaporation region of thermosyphon . analysis had been carried out to test the results . a physical model describing an enhanced boiling heat transfer in evaporation region were proposed based on the analysis results , thus providing theory references for development of heat pipe technology
文摘:通过对热虹吸管蒸发段强化传热进行可视化实验研究并对其结果进行分析讨论，在此基础上建立了热虹吸管蒸发段强化传热物理模型，为热管技术的发展提供理论依据 - First , according to the demand of vimp for resin system , the reaction kinetics and rheological of up resin are investigated and the optimal content of low additive profile ( lpa ) is determined . then vimp based on a high - permeable medium and grooves are studied by visual experiments , through which the appropriate high - permeable mediums are selected and the parameters of width , depth and spacing for flow grooves and spacing for supply grooves are optimized . furthermore , various factors affecting the mold filling process are discussed and the whole vacuum infusion procedures are described taking examples of the manufacture of a model boat and a sandwich panel in one infusion
文中首先根据vimp对树脂体系的要求，对vimp用不饱和聚酯树脂体系的动力学和流变学性能进行了研究，确定了最佳低收缩添加剂的含量；对高渗透介质型和沟槽型vimp开展了实验研究，通过可视化实验优选出较好的高渗透介质，确定了引流槽的宽度、深度和槽间距及主槽的槽间距等工艺参数并进行了优化；对影响充模过程的各种因素进行了详细的讨论，并以模型船和夹芯面板的制作为实例描述了两种vimp的成型过程；在实验的基础上，建立了二维渗漏模型，采用控制体有限元法对高渗透介质型vimp进行了成型过程的计算机模拟计算，通过充模时间和流动前峰的计算值与实验结果的比较，验证本文所采用的数学模型和数值方法的正确性，其结果对实际生产具有一定的理论指导意义。
