大家好，又见面了，我是你们的朋友全栈君。
要达到的效果是：
\begin{align*}
-\underset{t\rightarrow\infty}{\lim} & \int_{-\infty}^{t} dt^{\prime}%
\int_{-\infty}^{t^{\prime}}dt^{\prime\prime}
<\psi_{p}(t)|U^{(V)}(t,t^{\prime
})VU^{(V)}(t\prime,t^{\prime\prime})[-i\overleftarrow{\frac{\partial}{\partial
t^{\prime\prime}}}]|\psi_{0}(t^{\prime\prime})>\\
&= i\underset{t\rightarrow\infty}{\lim}\int_{-\infty}^{t}dt^{\prime}%
<\psi_{p}(t)|U^{(V)}(t,t^{\prime})VU^{(V)}(t\prime,t^{\prime\prime})|\psi
_{0}(t^{\prime\prime})>|_{t^{\prime\prime}=-\infty}^{t^{\prime}}\\
&\qquad +\underset{t\rightarrow\infty}{\lim}\int_{-\infty}^{t}dt^{\prime}%
{\int\limits_{-\infty}^{t^{\prime}}}dt^{\prime\prime}<\psi_{p}(t)|U^{(V)}%
(t,t^{\prime})VU^{(V)}(t\prime,t^{\prime\prime})[-i\overrightarrow
{\frac{\partial}{\partial
t^{\prime\prime}}}]|\psi_{0}(t^{\prime\prime})>
\end{align*}
