淺地層剖面儀是一種能夠對水底淺地層進行穿透而分辨不同地層剖面的測量 儀器，現已成為港口建設、通航工程等水運工程領域的關鍵設備。為了保證測量 結果的準確性，提高工程質量，急需開展淺地層剖面儀計量標準技術研究。文章 闡述了水深測量和垂直分辨力兩項技術指標的誤差原理，重點提出了這兩項指標 的量值溯源方法，進而填補我國淺地層剖面儀計量檢定/校準技術領域的空白，最後分析了建立淺地層剖面儀計量標準的研究問題

As an instrument to measure stratigraphic section of water bottom, sub-bottom profiler has been a key tool in harbour construction, navigation engineering and other fields of water transport engineering. To ensure right measuring result and improve project quality, it is badly in need of studying the measurement standard. This paper expounds the measuring error of depth and vertical resolution, and especially gives the method of traceability of value on depth and vertical resolution. It analyzes some questions about establishing measurement standard in the end. The study will fill in the blanks of metrological technology in sub-bottom profiler.
