通过作者参加爱荷华大学作家工作坊(Iowa Writers’Workshop)两堂英语翻译课的经历,真实、细致地记录了该校作家工作坊的授课方式和特点,进而延宕到作家工作坊的创办历史、招生方式、教学内容等具体情况。通过工作坊的课程安排与国内高校创写专业课程的比较,从小切口反思了中外创意写作教学中存在的一些共性问题和个性问题,并对中外地域性写作做了剖析,一方面地域性写作的共性叙事主题与美学风格在不断彰显中呈现出新的气象,超越了个体表达的局限性。另外一方面,对写作者按地域分类忽略了小说作为一种艺术表达方式的个性。

电动拖拉机具有结构简单和节能减排等优点,但现有电动拖拉机作业时采用单一动力电池能源,存在续航时间短的问题。为了提高电动拖拉机长续航供电能力,提出了一种基于下垂控制的直流双电源并联均流联合供电方案,利用MatLab/Simulink搭建了系统模型。仿真试验表明:单电源可以实现升压稳压控制;基于下垂控制的双电源并联均流能够实现双电源的电流均流;当切换不同功率负载时,系统电压随功率增加按比例下调,验证了该方案的可行性。
