用时一小时零8分。超级慢。
好处：
- 加强了对关键词记忆
- mathpazo
- shapes.geometric
- tikzpagestyle
- minimum
- trapezium
- trapezium left angle=70
- trapezium right angle=110
- rounded corners
- text centered
- diamond
- decision
- node()[]{}
- tikzstyle
\tikzstyle{arrow}=[thick,->,>=stealth]xshift- (dec1)- -node[]{}(pro2a)
- anchor=north
- 学习了一种配色
- 开始结束 red!30
- 输入输出 blue!30
- 操作 orange!30
- 判断 green!30
通过写上面的要点，我相信，明天写一遍这个流程图会提高一些效率。
掌握一个工具需要一个过程，只是不知道需要多久。
总结要点用时13分钟。
