在 LaTeX 中拆分一组长方程式

我有 3 个很长的方程。这些方程应该是子方程，应该拆分和对齐。它们也应该被赋予标签。我在下面附上了代码。

\begin{subequations} \label{e33}
\begin{align}
\begin{split}
      q^{*}& = \Bigg(\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}\Bigg)\  \overline{C}_1\overline{C}_3 - \Bigg(G_1^{*} +\overline{C}_2(T_p^{*}+T_1^{*})\cos\theta+G_2^{*}\overline{C}_1+G_3^{*}\overline{C}_1\overline{C}_3+ \overline{C}_1\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta\Bigg)\  (\dfrac{W_{(i-1)}-2W_i+W_{(i+1)}}{(\Delta X)^{2}}) \label{e33a} 

        %\frac{\partial T_1^{*}}{\partial X}& = -\Bigg(q^{*}+G_1^{*}\frac{\partial^{2}W}{\partial X^{2}}\Bigg)\  \overline{D}_1 - \Bigg(\overline{C}_3\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)} - \Big(G_2^{*}+G_3^{*} \overline{C}_3+\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta \Big) \frac{\partial^{2}W}{\partial X^{2}}\Bigg)\  \overline{D}_2 \label{e33b} \\
        %\frac{\partial T_2^{*}}{\partial X}& = -\Bigg(\frac{1}{\overline{C}_1} \Big(q^{*}+\bigg(G_1^{*}+\overline{C}_2(T_p^{*}+T_1^{*})\cos\theta \bigg)\frac{\partial^{2}W}{\partial X^{2}} \Big) +G_2^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_3 - \Bigg(\dfrac{\alpha^{*} W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)} - G_3^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_4       \label{e33c}
%\end{split}
%\end{align}
%\end{subequations}

请给我提供同样的建议。

这是第一次尝试：

\begin{subequations}
\begin{equation}\label{e33a}
\begin{split}
  q^{*} = & \Bigg(\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}\Bigg)\  \overline{C}_1\overline{C}_3
  - \left(\dfrac{W_{(i-1)}-2W_i+W_{(i+1)}}{(\Delta X)^{2}}\right) \times \\
  & \Bigg(G_1^{*} +\overline{C}_2(T_p^{*}+T_1^{*})\cos\theta+G_2^{*}\overline{C}_1+G_3^{*}\overline{C}_1\overline{C}_3
  + \overline{C}_1\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta\Bigg)
\end{split}
\end{equation}
\begin{equation}\label{e33b}
\begin{split}
  \frac{\partial T_1^{*}}{\partial X} = & -\Bigg(q^{*}+G_1^{*}\frac{\partial^{2}W}{\partial X^{2}}\Bigg)\  \overline{D}_1
    - \overline{D}_2 \Bigg(\overline{C}_3\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)} \\
   & - \Big(G_2^{*}+G_3^{*} \overline{C}_3+\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta \Big) \frac{\partial^{2}W}{\partial X^{2}}\Bigg)
\end{split}
\end{equation}
\begin{equation}\label{e33c}
\begin{split}
  \frac{\partial T_2^{*}}{\partial X} = & -\Bigg(\frac{1}{\overline{C}_1} \Big(q^{*}+\bigg(G_1^{*}
  + \overline{C}_2(T_p^{*}+T_1^{*})\cos\theta \bigg)\frac{\partial^{2}W}{\partial X^{2}} \Big)
    +G_2^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_3 \\
  & - \Bigg(\dfrac{\alpha^{*} W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}
  - G_3^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_4
\end{split}
\end{equation}
\end{subequations}

我认为它仍然太混乱了。我可能会在中间放一些文字，并将每个方程式放在multline而不是 中split。

更新：好的，我认为下面的内容更好：

\begin{subequations}
Introductory text.
\begin{align}
  q^{*} = & \Bigg(\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}\Bigg)\  \overline{C}_1\overline{C}_3
    - \left(\dfrac{W_{(i-1)}-2W_i+W_{(i+1)}}{(\Delta X)^{2}}\right) \times \label{e33a}\\
  & \Bigg(G_1^{*} +\overline{C}_2(T_p^{*}+T_1^{*})\cos\theta+G_2^{*}\overline{C}_1+G_3^{*}\overline{C}_1\overline{C}_3
    + \overline{C}_1\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta\Bigg) \nonumber \\
\intertext{First intermissive text.}
  \frac{\partial T_1^{*}}{\partial X} = & -\Bigg(q^{*}+G_1^{*}\frac{\partial^{2}W}{\partial X^{2}}\Bigg) \; \overline{D}_1 \label{e33b} \\
  & - \Bigg(\overline{C}_3\dfrac{\alpha^{*}W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}
    - \Big(G_2^{*}+G_3^{*} \overline{C}_3+\overline{C}_4(T_p^{*}+T_2^{*})\cos\theta \Big)
    \frac{\partial^{2}W}{\partial X^{2}}\Bigg) \; \overline{D}_2 \nonumber
\intertext{Second segway.}
  \frac{\partial T_2^{*}}{\partial X} = & -\Bigg(\frac{1}{\overline{C}_1} \Big(q^{*}+\bigg(G_1^{*}
    + \overline{C}_2(T_p^{*}+T_1^{*})\cos\theta \bigg)\frac{\partial^{2}W}{\partial X^{2}} \Big)
    + G_2^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_3 \label{e33c} \\
  & - \Bigg(\dfrac{\alpha^{*} W}{U\big(1+\alpha^{*}(\frac{W}{q_u^{*}})\big)}
    - G_3^{*}\frac{\partial^{2}W}{\partial X^{2}} \Bigg)\ \overline{D}_4 \nonumber
\end{align}
\end{subequations}
