１９９５年２月２６日至３月６日，在琼州海峡的新海一四塘断面上，大小潮期间进行１５条船同步测流．该断面上涨潮流速普遍大于落潮流速，实测最大涨潮流速为１７２“ｃｍ／ｓ，最大落潮流速为１４２ｃｍ／ｓ；大潮期间北部６个站全层平均余流速度为１８．４ｃｍ／ｓ．“海峡中间３个站０～２０ｍ层平均流速为１８．３ｃｍ／ｓ，南部６个站平均余流速度为１０．２“ｍ／ｓ。中间和北部诸站余流方向指向Ｗ一Ｓ范围，南部６个站因受地形影响，流向指向ＮＥ。用数值计算方法，再现了大小潮期间琼州海峡整个潮流场．大潮期间，通过西断面（灯楼角──玉苞角）落潮流总通量为４．７３Ｘ１０１０ｍ３，涨潮流总通量为４．２９Ｘ１０１０ｍ３；通过东断面（东营──龙塘镇）落潮流总通量为５．２２Ｘ１０１０ｍ３，涨潮流总通量为４．９０Ｘ１０１０ｍ３，其净通量，西、东断面分别为０．４３Ｘ１０１０和０．３２×１０１０ｍ３，其方向指向西．
From February 26 to March 6, 1995, a total of 15 vessels were simultaneously measured on the Xinhai-Xiantang section of the Qiongzhou Strait over the period of large and small tides. The rising tide velocity in this section was generally larger than that of the ebb tide, and the maximum tidal current velocity was 172 cm / s and the maximum ebb flow velocity was 142 cm / s. The average overcurrent velocity of the 6 stations in the north during the tide was 18.4 cm / s. The average flow velocity at the 0 ~ 20m layer in the middle 3 stations was 18.3cm / s and the average flow rate at the 6 stations in the south was 10.2 "m / s. The residual flow directions at the middle and northern stations point to the W-S range, Due to the terrain, the stations flow to NE, and the entire tidal flow field in the Qiongzhou Strait during the tidal period is reproduced numerically. During the tide, the total flux of the tide current through the west section (lampshade angle-Yujiao angle) is 4 .73X1010m3, the total flux of the tidal current is 4.29X1010m3; the total tidal current flux through the east section (Dongying-Longtang) is 5.22X1010m3, the total flux of the tidal current is 4.90X1010m3, its net flux, , East section were 0.43X1010 and 0.32 × 1010m respectively Its direction toward the West.
