我正在将一篇论文转换为双列模式（使用 \documentclass[twocolumn]{article}），现在我的一个方程式上方和下方有太多空白。请参阅附图（方程式 (8)）。我该如何修复此问题？
在这种情况下，我不知道如何提供一个最小的工作示例，但这里有一个围绕该等式的 Latex 代码片段：
\subsubsection{Moreau-Yosida regularization}
\label{mySection}
Convex analysis provides an elegant way of smoothing out nondifferentiable
convex functions.
Let $f: \mathbb R^m \to \mathbb R \cup \{ \infty \}$ be closed and convex.
The Moreau-Yosida regularization of $f$ with parameter $t > 0$ is defined by
\begin{equation}
\label{myRegDef}
f^{(t)}(x) = \inf_{u \in \mathbb R^m} f(u) + \frac{1}{2t} \| u - x\|_2^2.
\end{equation}
It can be shown that $f^{(t)}:\mathbb R^m \to \mathbb R$ is a convex, \emph{differentiable}
approximation to $f$, and that the gradient of $f^{(t)}$ is given by the formula
\begin{equation}
\label{myGrad}
\nabla f^{(t)}(x) = \frac{1}{t} (x - \prox_{tf}(x)).
\end{equation}
The gradient of $f^{(t)}$ is Lipschitz continuous with Lipschitz
constant $L = 1/t$.
