尔斯有凶，名僮狰，群居以存，有度人化己之能。
代代相争，新必讨旧，无异代共存之道。
作驯兽以助态近人，善久和以温吞，食民脂民膏，啖鱼肉百姓。
天下之人得之必诛，然兽善伪，人为兽操以无力。
兽法尔斯，虽数聚人力群起讨兽，形灭，魄能人以续。
人兽疲，默通规：兽止猖，人从兽，兽为食，人为己。
久之，人以化兽为大道，兽乐以食无尽，人乐以疲无尽。

二阶系统 PD 校正后在阶跃响应下时域指标的计算
自控课设的题目有对 PD 校正后系统分析的要求，课本上一般只对二阶标准型系统计算指标，而 PD 校正后的系统不再是书上的标准型，变成了带实零点的二阶标准型，计算公式也不再适用，经查找资料后得出解决办法，记录在此。
一般形式的计算
基础公式
由图 1 可计算出系统的开环传递函数
$$G (s) = \frac {C (s)}{E (s)} = \frac {K\left (T_{d} s+1\right)}{s\left [s /\left (2 \zeta \omega_{n}\right)+1\right]} \tag {1.1}$$
其中 $K=\frac {\omega _{n} }{2\zeta } $ ，称为开环增益。令 $z=\frac {1}{T_{d} } $ ，则闭环传递函数为
$$\Phi (s)=\frac {\omega_{n}^{2}}{z} \cdot \frac {s+z}{s^{2}+2 \zeta_{d} \omega_{n} s+\omega_{n}^{2}} \tag {1.2}$$
其中$$\zeta_{d}=\zeta+\frac {\omega_{n}}{2z} \tag {1.2.1}$$
盒子里到底有什么
“请不要打开这个盒子”？这可不就是在说 “快看看盒子里有什么！” 嘛
To：Cheems of the future…
把 “Cheems，你要去码头整点薯条吗？” 这个视频中 Cheems 写给未来自己的信摘了出来。
To: cheems of the future…
Hello, long time no see.
I am the past you.
When you think of this letter…
You should be an adult.
Have you fulfiled our dream?
Or, not done by life?
I don’t know.
But, cheems…
Never stop chasing.
I know it may be difficult…
Even if I tried hard, the flame of hope can’t be lit.
But, cheems…
If one day…
I give up.
Bury our dreams..
Well, no matter how many times.
Please must held your courage again…
Pick up your shovel again and dig out the dream again!
Our stories should not be buried deep in the ground…
But should store in the sky!
No matter how many times we’ve been knocked down,
don’t forget the power of dreams.
Go to the end of the Earth.
But it’s not just the end of the Earth…
To see the endless wilderness,
go and see the mountains stretching thousands of miles,
go and see the waterfall flowing straight down,
go and see the clear and clean lake,
no why, just because I wanted to go.
Isn’t that the best life?
蓝色的邀请
You're Not Late! You're Not Early
在我寻找应对同侪压力的办法时，找到了这首小诗。
New York is 3 hours ahead of California,
but it does not make California slow.
Someone graduated at the age of 22,
but waited 5 years before securing a good job!
Someone became a CEO at 25,and died at 50.
While another became a CEO at 50,and lived to 90 years.
Someone is still single,while someone else got married.
Obama retires at 55,but Trump starts at 70.
Absolutely everyone in this world works based on their Time Zone.
People around you might seem to go ahead of you,
some might seem to be behind you.
But everyone is running their own RACE, in their own TIME.
Don’t envy them or mock them.
They are in their TIME ZONE, and you are in yours!
Life is about waiting for the right moment to act.
So, RELAX.
You’re not LATE. You’re not EARLY.
You are very much ON TIME, and in your, TIME ZONE Destiny set up for you.
远浪情诗 ——《魁拔 3》
《魁拔 3》中海盗哥哥写给鳞妖远浪的花痴诗。
我的小鱼你醒了，
还认识早晨吗？
昨夜你曾经说，
愿夜幕永不开启，
你的香腮边轻轻滑落的，
是你的泪，
还是我的泪？
初吻吻别的那个季节，
不是已经哭过了吗？
我的指尖还记忆着，
你慌乱的心跳，
温润的体香里，
那一绺长发飘飘……
我 - 演讲 - 李老师
她是我初中的第一位语文老师，也是我第一位有 “好想还让她教我啊” 想法的老师。
她有着高高的额头，现在想来也是发际线高高，戴着副那种一看就让人感觉很严肃的眼镜，个子不算高，讲课时总会不自觉地在句子停顿处加上 “额”“啊” 之类的语气词，脸上长年无笑，她很严厉，时间长了，班里的淘气鬼们背地里就称她 “鬼子”，最常听到的是在她上课前一声 “鬼子来了！”，但，她教学很认真，人很好。这就是在漫长时间的冲涮下她留在我记忆里的样子。
我与她交集最多的时候是因为一个学校组织的演讲比赛，学雷锋月的，至于为什么我们班会选中我去参加，我不记得了，大概只是因为我的普通话稍微好一点吧。她给我准备了稿子，早读的时候读，课间的时候读，晚饭过后去她宿舍那边站在院子里，我读，她边忙家务边听我读。
