根据 １３７° Ｅ 断面 １９６７～１９９５ 年冬、夏季的温、盐资料，计算和分析该断面的地转流。主要结果是：（１） 黑潮是流速很强且较稳定的单支海流，没有多支现象；黑潮逆流则不同，有时为单支，有时为２ 支甚至３ 支出现，带有多支性成份；（２） 多年平均而言，该断面上３１° Ｎ 为黑潮与黑潮逆流的分界线。冬季，黑潮主要出现在３１°～３３° Ｎ 之间，黑潮逆流主要出现在２９°～３０° Ｎ之间；夏季，黑潮主要出现在３１°～３４° Ｎ 之间，黑潮逆流主要出现在 ２８°～３１° Ｎ 之间；（３） 该断面 ２６°～３４° Ｎ 之间的流速结构，可划分为Ⅰ、Ⅱ、Ⅲ３ 种类型，２ 支海流均为带状的单核结构。平均而言，黑潮与黑潮逆流流速均具有夏强冬弱的现象，但后者冬、夏季差异不显著。对黑潮逆流的多支性用实测资料进行了比较
Based on the temperature and salinity data of 137 ° E section from 1967 to 1995 in winter and summer of 1995, the earth-side flow of this section was calculated and analyzed. The main results are as follows: (1) The Kuroshio is a fast and stable single-stream current with no multi-branch current. The Kuroshio current is different, sometimes single, sometimes two or even three, with multiple branches (2) For many years, 31 ° N on the cross section is the dividing line between Kuroshio and Kuroshio Current. In winter, the Kuroshio mainly appeared between 31 ° and 33 ° N, and the Kuroshio current mainly appeared between 29 ° and 30 ° N. In summer, the Kuroshio mainly occurred between 31 ° and 34 ° N, and the Kuroshio Current Mainly between 28 ° and 31 ° N; (3) The velocity structure between 26 ° and 34 ° N can be divided into three types Ⅰ, Ⅱ and Ⅲ, and the two currents are banded mononuclear structure. On average, both the Kuroshio and Kuroshio Current velocities are weak in summer and winter, but the latter are not significantly different in winter and summer. The Kuroshio Current has been compared with measured data using multiple data
