latex aligned 公式对齐技巧

嵌套对齐

效果

代码

\begin{align*}
    &\begin{aligned}
        a+b=b+c
    \end{aligned}\\
    &\begin{aligned}
        d={}&a+b+c\\
        &+d
    \end{aligned}
\end{align*}

靠左对齐

效果

代码

\begin{flalign}
x &= t &\\
y &= 2t &
\end{flalign}

利用hspace调整宽度对齐

效果

代码

\begin{alignat*}{2}
    &\frac{\sqrt{3}}{2}[\delta a_{i}(t)+\delta a_{j}(t)]=\\
    &&\frac{\sqrt{3}}{2}(\delta\overline{a}_{0i}+\delta\overline{a}_{0j})+\frac{\sqrt{3}}{2}[a_{i}^{s}(t)+a_{j}^{s}(t)]\\
    &\frac{1}{2}a_{\mathrm{o}}\delta\lambda_{ji}(t)=\\
    &&\frac{1}{2}a_{\mathrm{o}}\delta\overline{n}_{ji}(t-t_{0})+\frac{1}{2}a_{\mathrm{o}}[\delta_{\Delta}\lambda_{ji}^{c}(t)+\delta_{\Delta}\lambda_{ji}^{l[c]}(t)]\\
    &&+\frac{1}{2}a_{\mathrm{o}}\delta\overline{\lambda}_{0ji}+\frac{1}{2}a_{\mathrm{o}}[\delta\lambda_{ji}^{l[l]}(t)+\delta\lambda_{ji}^{s}(t)]\\
    &\frac{\sqrt7}{2}a_{\mathrm{o}}[\sin M_{\mathrm{o}j}^{-}(t) \delta e_{j}(t)-\sin M_{\mathrm{o}i}^{+}(t) \delta e_{i}(t)]=\hspace{-2cm}\\
    &&\frac{\sqrt{7}}{2}a_{\mathrm{o}}[\sin M_{\mathrm{o}j}^{-}(t) e_{j}(t)-\sin M_{\mathrm{o}i}^{+}(t) e_{i}(t)]
