📅 21-11 上月总结与本月规划

上月总结

学生工作记录

根据 2021 年校历与实际情况，上月月底与本月月初为研究生期中考试周，所以需要花时间复习。刨除复习周，上个月的前三周还准备了若干个 Presentation，因此在课题上所花的时间不足以完成导师给定的任务，换言之，上个月还没有平衡好课程与科研之间的精力分配。

此外因为 425 要搬进来新的课题组，可能失去原有工位，所以上个月未雨绸缪将杂物搬回了宿舍，但是还没有踩点自习替代方案——涵泳图书馆，争取即使搬离工学院，也不要再重蹈先前昼夜颠倒的覆辙。

本月规划

生活

  • 期中复习时熬夜比较多，因此本月争取在 1 点前入睡；
  • 躺床上玩手机时间比较多，因此本月上床后把手机放在桌子上；
  • 老生常谈：平衡好课程与科研之间的精力分配、适当合群。

课题

  • 构建不同求解器下的液滴碰撞案例，并提交计算。
