如何配置 \label 的 \ref 以打印更多内容（而不仅仅是数字）？

我在方程中使用了\label和\ref。例如

\begin{equation} 
\label{eq:grav} F=\frac{G m_{1} m_{2}}{r^{2}}
\end{equation}

如方程式所示\ref{eq:grav}

打印方程式排列顺序的数字（参考文档中的其他方程式）。

我希望它不仅打印数字，还打印单词“方程”，因为我总是需要说它是一个方程，所以不必总是手动输入就好了。数字也是一样。

有没有办法在序言中定义这一点？

\documentclass{report}
\usepackage{hyperref} %% to turn the links clickable and load this before cleveref
\usepackage{cleveref}

% each of the following has two versions
%   \crefname{environmentname}{singular}{plural}, to be used mid-sentence
%   \Crefname{environmentname}{singular}{plural}, to be used at the beginning of a sentence
\crefname{table}{table}{tables}
\Crefname{table}{Table}{Tables}
\crefname{figure}{figure}{figures}
\Crefname{figure}{Figure}{Figures}
\crefname{equation}{equation}{equations}
\Crefname{Equation}{Equation}{Equation}
\begin{document}

\begin{figure}[!htb]
  \centering
  \rule{20pt}{20pt}
  \caption{My figure}
  \label{fig:myfig}
\end{figure}

\begin{equation}
\label{eq:grav} F=\frac{G m_{1} m_{2}}{r^{2}}
\end{equation}

\begin{itemize}
  \item Use \cref{fig:myfig} mid sentence.
  \item \Cref{fig:myfig} is appropriate for the beginning of a sentence and~\cref{eq:grav}. \Cref{eq:grav} is printing \verb|Equation| rather than \verb|equation|.
\end{itemize}

我提供的与 Harish Kumar 提供的类似，但我提供了一些附加选项。下面我提供的是一个样式文件，eqcite.sty

\ProvidesPackage {eqcite} [2006/11/29]
%
% by Steven B. Segletes, for the public domain.
%
% eqcite prints out the preferred reference format for equation
% citations, e.g., equation 1 as opposed to eqn(1), eq.(1), etc. 
%
% Advantages of using eqcite:
% 1) Ability to quickly change from `equation x' to `eqn(x)' through
%    whole document, with a single line change (\EqTypeB).  This is 
%    useful when converting from tech report to manuscript formats;
% 2) Saves typing:
%    With the eqcite package, type        `\eqcite{eq:myeqn}'
%    vs. the traditional LaTeX approach of `equation~\ref{eq:myeqn}'  .
%
%
% A number of format types are predefined:
%
% EqTypeA : equation x, equations x and y   (ARL report standard)
% EqTypeB : eqn(x)    , eqns (x) and (y)
% EqTypeC : eq(x)     , eqs (x) and (y)
% EqTypeD : eqn.(x)   , eqns. (x) and (y)
% EqTypeE : eq.(x)    , eqs. (x) and (y)
% EqTypeF : eqn (x)   , eqns (x) and (y)
% EqTypeG : eq (x)    , eqs (x) and (y)
%
% Other format types are easily added.
%
% Usage:
%
% % In Preamble:
% \usepackage{eqcite}
% \EqTypex  % where `x' is A, B, etc.  defaults to EqTypeA
%
% % In Document:
% \Eqcite{ref} ...
% ... \eqcite{ref} ...
% \Eqcites{ref1}, \andeqcite{ref2}, and \andeqcite{ref3} ...
% ... \eqcites{ref1}, \andeqcite{ref2}, and \andeqcite{ref3}...
%
% where ref is the LaTeX reference, for example, eq:myeqn  .
%
% A literal option [l] is available to use the the argument as the
% actual equation number, rather than as an equation reference:
%
% \eqcite[l]{13}
%
% This literal option can be used with the following calls:
% \Eqcite, \eqcite, \Eqcites, \eqcites and \andeqcite.

首先，您可以指定 EqType，其中类型可以是“equation”、“eqn”等。然后，它为引用提供复数、单数、大写、连词和文字选项。
