<p>这个命令和 <code class="docutils literal notranslate"><span class="pre">GEORADIUS</span></code> 命令一样，
都可以找出位于指定范围内的元素，
但是 <code class="docutils literal notranslate"><span class="pre">GEORADIUSBYMEMBER</span></code> 的中心点是由给定的位置元素决定的，
而不是像 <code class="docutils literal notranslate"><span class="pre">GEORADIUS</span></code> 那样，
使用输入的经度和纬度来决定中心点。</p>
<p>关于 <code class="docutils literal notranslate"><span class="pre">GEORADIUSBYMEMBER</span></code> 命令的更多信息，
请参考 <code class="docutils literal notranslate"><span class="pre">GEORADIUS</span></code> 命令的文档。</p>
