The pion and kaon production in heavy-ion reactions at 1GeV/nucleon has been investigated in the relativistic Vlasor-Uehling-Uhlenbeck model, which has been generalized to include the effect of nuclear medium on kaon and pion. The calculated results show that the attractive pion optical potential not only enhances apparently the yield of pions with low transverse momenta, leading to a reasonable fit to the experimental data, but also increases the kaon abundance.

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。
