<h4 id="简介">简介</h4>
|
||
<p>drtp程序可计算变磁化参数（磁偏角与磁倾角）的化极磁异常，适用于大陆磁异常数据的化极处理。程序可计算或读入标准IGRF程序生成的主磁场参数，并计算相应的化极磁异常。程序适用于网格化的总场磁异常数据的处理，网格文件的格式为netCDF格式。</p>
|
||
<h4 id="程序用法">程序用法</h4>
|
||
<p>如下所示，drtp程序可通过命令行调用，参数为配置文件的名称（包含路径）。</p>
|
||
<pre><code class="language-cxx">./drtp <config-file>
|
||
</code></pre>
|
||
<p>配置文件为普通文本文件，注释行以<code>#</code>号开始。文件中每一行包含一条选项配置，格式为：</p>
|
||
<pre><code class="language-shell"><key> = <value>
|
||
</code></pre>
|
||
<h5 id="选项列表">选项列表</h5>
|
||
<p>如下为程序可识别的选项键值与相应的选项格式：</p>
