摘　　要：测量浅层海流是比较困难的,在波浪区内,测流仪器的运载体和海流计本身都会受到影响,因而在室内静水槽中检定合格的海流计,在实际海洋中动态条件下使用,其测量值和实际值会产生较大差别,降低了所测数据的准确度,本文简要说明了浅层测流时产生误差的原因和海流计的选用原则,并介绍了几种浅层测流的方法。It's quite difficult to measure the current in ocean shallow water. The carrier of the current meter and the current meter itself undergo the influence of wave zone.There will be some discrepancies between the real current and the current mea- sured by a current meter qualified in tow-tank test under dynamic condition in real oceau.Asa subsequence of this, the accuracy of measurement decreases. The fa- cts resulting in errors of current measurement in shallow water and the principle for selecting the current meter are described in this paper. Several methods of current measurement in shallow water are also presented.
