时间Fri May 23 00:02:15 2008
when potential is even, the ground state wave function is also even.
does anyone know why?

1F：推 Frobenius:什麽叫做 potential is even？ 05/23 00:20
2F：推 ncuarthur:他是指偶对称和奇对称吧 05/23 00:31
3F：→ beatitude:potential is even function 05/23 00:31
4F：推 force123:奇偶定理知位为偶则波函数非偶即奇 振荡定理知基态领零节 05/23 00:36
5F：→ force123:点故为偶 05/23 00:38
6F：→ beatitude:what is 振荡定理? 05/23 00:47
7F：推 force123:oscillating thm 第n激发态有n个节点 05/23 00:53
8F：→ force123:第0激发态 即基态 05/23 00:57
9F：推 peter308:从对称性来的...你把位能势-x=>x ,看到的物理不变 05/23 00:59
10F：→ beatitude:how can i know that 第n激发态有n个节点? 05/23 01:05
11F：推 force123:无限深位井是最简单的例子 一般证明可见Landau或孙超群笔 05/23 01:15
12F：→ force123:记 05/23 01:15
13F：推 force123:上例驻波条件是n+1个半波长 因而n个节点 05/23 01:22

15F：推 force123:不客气 05/23 01:33
16F：推 sputtering:p兄正解 05/23 19:16
