步骤7：在投放化学物质粉末之后，活塞位于集水装置最下方，集水装置内无液体，此时可通过控制台将推进杆向上收回，同时，连接金属条牵引底盖逐渐闭合以及活塞向上运动使装置充满水，由于浓度测试仪与装置内部为连通状态，测试液体收集完毕，将集水装置中的液体排出并重新收集溶洞内液体，通过浓度测试仪对收集的液体进行浓度测量，重复测量三次并依次记录数值ρ 1、ρ 2、ρ 3，取三次测量结果平均值ρ，已知化学物质质量为m，经过公式计算得到充水溶洞最终体积V；其计算公式如下：

当仪器浸入水中时，位于装置最底端的集水装置能够自由完成给排水即可，所述的集水装置用来提取溶洞内的水以便于进行浓度测量。

    步骤7：将集水装置中的液体排出，并重新收集溶洞内液体，通过浓度测试仪对收集的液体进行浓度测量，重复测量多次并依次记录数值，取多次测量结果平均值ρ，已知化学物质质量为m，经过公式
    Figure PCTCN2019082304-appb-100001
    计算得到充水溶洞最终体积V；
    步骤8：完成测量工作，将仪器设备收回至地面。
  5. 如权利要求4所述的方法，其特征在于，所述的化学物质为一种不与水或者空气中的成分发生反应的物质，将其放入水中时，可以在液体中迅速扩散。
  6. 如权利要求4所述的方法，其特征在于，所述的浓度测试仪在被测量物质浓度值趋于稳定后，会自动记录该数值并发出提示。
