那才是真正的杯具
兩星期前某作業用 Exp(-r1/a) - Exp(-r2/a) 去試H2+的Energy...
二参数就可以安逸了
多fermi子和bose子组合统计...

還有其他作業要交就已經夠令這個變杯具吧
話說某題有人做了20頁....
这个扩展的真厉害

所以大部分人是直接放棄
詳見PS.
PS. problem:
Use Exp(b1r1+b2r2) + Exp(b2r1+b1r2) to show that H- is bounded

shall index be negative？
or it should be a conclusion
=============================
it most like to try to find the ground-state energy ...
H=H(1)+H(2)
H(i) is hamiltonian of each electron
get the average of H at the given trial wave function
according to the variational principle，find the minimum
and that should a proper value
b1 and b2 are parameters
exactly, but the calculation can be up to 20 pages long if hand written
especially the integral calculation
i'm now prefer theory to numerical

there's an invention called computer to handle those stuff called numerical calculation
for sure life becomes easier
终于也要加入到搔扰人的行列了么…

總是被人用小喇叭噪音攻擊不是很爽{:neko_14:}
一早應該
耳機傷耳

一直都懶得去買.....
calculus不算甚麼
讀analysis突然殺出一大堆topolgoy然後說[a,b)是個閉集合才是真正的吐血

還好我只有大一要修微積分.....

即是被人爽吧
非常標準的答案
that's the fun part in science, go and ask TS
.....
隨便出去買個東西就要三四小時.....
會吐血的還會fun?
随便买个东西要那么久
又不是大小姐逛街
发现TK菌换头像了
差不多吧
又要走路又要坐巴又要坐捷運......
順便吃晚飯.....
居然被人看到了{:neko_04:}

正常
that's why i tell u to ask TS y it's fun
probably he's enjoying that now

比著以前會覺得很不正常
不錯...................................
路过发现无话可说………………
話和水有點不同.......

兩個根本不可比
所以快快去讀多一兩科數玩玩吧
