     We introduce the following auxiliary variables:
-    \begin{equation}
+    \[
+    \scalebox{0.8}{$\displaystyle
         \dlapse{_i} \definedby \Partial{_i} \lapse \qc
           \dshift{^i_j} \definedby \Partial{_j} \shift{^i} \qc
           \dchi*{_i} \definedby \spaceD*{_i} \ln(\chi) \qc
           \dsmetric*{_i_j_k} \definedby \Partial{_i} \smetric*{_j_k},
-    \end{equation}
+    $}
+    \]
     and replace all the spatical derivatives of the original variables with the new auxiliary variables, we got this
     \[
