这种“手工调整”在MathJax中好像不行, 测试:
另:此时$\begin{aligned}
f'(z)&=\frac{\partial u}{\partial x}+i\frac{\partial v}{\partial x}\\
&=\frac{\partial v}{\partial y}+i\frac{\partial v}{\partial x}\\
&=\frac{\partial u}{\partial x}-i\frac{\partial u}{\partial y}\\
&=\frac{\partial v}{\partial y}-i\frac{\partial u}{\partial y}\\[-77pt]
\end{aligned}$
在amsmath中使用[t], [b]和默认的[c]来指定纵向对齐, 见amsmath doc
Like the array environment, these -ed variants also take an optional [t], [b] or the default [c] argument to specify vertical positioning. For maximum interoperability, do not insert a space or line break before the option. See also the note on page 10 regarding page breaking within the -ed environments.
