目的:建立本土化的中国面部表情视频系统(chinese facial expression video system,CFEVS)以增加情绪研究的取材范围。方法:录制强度分为三等级的喜悦、悲伤、惊奇、恐惧、愤怒、厌恶及中性(无表情及咀嚼动作两种)等面部表情视频片段,...目的:建立本土化的中国面部表情视频系统(chinese facial expression video system,CFEVS)以增加情绪研究的取材范围。方法:录制强度分为三等级的喜悦、悲伤、惊奇、恐惧、愤怒、厌恶及中性(无表情及咀嚼动作两种)等面部表情视频片段,经两轮粗选后,请50名中国大学生对剩余视频片段的表情类型、愉悦度、唤醒度及表演者的长相进行自我报告式评定。将表情类型、愉悦度、唤醒度一致性高且表情类型与愉悦度相一致的片段纳入CFEVS,做分布分析,同时分析评测者性别、表演者长相对愉悦度、唤醒度分值的影响。结果:纳入CFEVS的喜悦表情男18女43共61个,悲伤表情男23女28共51个,无表情中性男13女17共31个,咀嚼中性男7女17共24个。散点图显示CFEVS在愉悦度及唤醒度上分布较为广泛。方差分析表明评测者性别及表演者长相对视频片段的愉悦度、唤醒度的影响与其表情类型有关。结论:本研究初步建立了一个拥有喜悦、悲伤及中性表情的CFEVS,并发现评测者的性别及表演者的长相可影响实验结果。展开更多

As the vast majority of these areas are without an electrical power lines infrastructure, the need arose for a highly reliable and maintenance-free power supply to allow the continuous operations of these projects. ORC (Organic Rankine Cycle) based on CCVT (closed cycle vapor turbogenerator) was specially developed for the special requirements. The paper presents the CCVT and its mode of operation, design criteria and case studies in projects implemented in the last 45 years.展开更多
