In revtex4-1 onecolumn, I find the extra-long blanks (sentence breaks) before/after eqnarray, like this

enter image description here

question: How to remove the extra long blanks before/after eqnarray? 

\documentclass[11pt, notitlepage, nofootinbib, onecolumn,preprintnumbers,amsmath,amssymb,prr,superscriptaddress,noshowpacs]{revtex4-1}
    \begin{document}

    Here here here:
    \begin{eqnarray}
    1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,
    \end{eqnarray}
    There there there:
    \begin{eqnarray}
    1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,
    \end{eqnarray}

    \end{document}

One stupid way I can do is this:

\documentclass[11pt, notitlepage, nofootinbib, onecolumn,preprintnumbers,amsmath,amssymb,prr,superscriptaddress,noshowpacs]{revtex4-1}
    \begin{document}

    Here here here:
    \begin{eqnarray}\\[-14mm]
    1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,
    \end{eqnarray}
    There there there:
    \begin{eqnarray}\\[-14mm]
    1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,
    \end{eqnarray}

    \end{document}

which gives (this is more or less the normal line break width that I wish to have) enter image description here

But this is pretty inefficient and bad looking. Comments? Thanks!

    You have a large line spacing. Also the space between two lines of ordinary text is double. –  Feb 20 '20 at 05:32

    Just out of idle curiosity: Why do set both showpacs and noshowpacs as document class options? – Mico Feb 20 '20 at 08:27

    The revtex4-1 class uses the standard value for \abovedisplayskip. My opinions about this are: (1) the default value is a bit too large; (2) your expected output is typographically poor. Some other points: nobody should be using eqnarray nowadays; the revtex4-2 class has been available for a few months. – egreg Feb 20 '20 at 09:09

  • nobody should be using eqnarray nowadays; Q: thanks. then what should we use?

  • but even if I use \begin{align} ... \end{align}, there are still a large break between lines. How can I avoid? How does \abovedisplayskip work? – wonderich Feb 21 '20 at 00:00
  • As @Schrödinger'scat pointed out the issue has nothing to do with eqnarray or align. You simply have a large line spacing. You can use the class option tightenlines to reduce it. Note also that prr is not a valid option. – campa Feb 21 '20 at 10:05
