一个不平稳的时间序列，通过一次差分之后，ADF检验结果如下

Null Hypothesis: LQTY has a unit root
Exogenous: Constant
Lag Length: 0 (Automatic based on SIC, MAXLAG=11)

t-Statistic Prob.*

Augmented Dickey-Fuller test statistic -11.50759 0.0001
Test critical values: 1% level -3.512290
5% level -2.897223
10% level -2.585861

是不是说差分后序列 平稳了？

但是差分后序列相关图如下

Date: 08/30/07 Time: 13:49
Sample: 2000M01 2007M12
Included observations: 83

其伴随概率绝大部分都大于0.05，请问是什么意思
