摘　　要：The B/ A values of NaCl solution and arhficial seawater (prepared by LymanFleming formula) with different salinities and temperatures are measured and compared with the calculated B / A values in literature. The results show that the B / A values of NaCl solution increase linearly with increasing temperature and slightly with increasing salinity; the B / Avalues of artificial seawater increase linearly as temperature increases; basically, thc values match those obtained in literature[1]; NaCl solution can be used to simulate seawater approximately.The B/ A values of NaCl solution and arhficial seawater (prepared by LymanFleming formula) with different salinities and temperatures are measured and compared with the calculated B / A values in literature.
