珠江闽江船舶航速预报算法开发及实船验证

根据内河船模试验数据对船舶有效功率估算方法艾尔法进行修正,应用图谱回归公式计算螺旋桨推进功率,考虑船机桨匹配进行珠江、闽江船舶航速预报,通过实船试验对航速预报结果进行验证,结果表明,预报结果符合工程精度,具有良好的实用性,可用于珠江、闽江现有船舶标准化认定工作。

Underway Measurement of Sea Surface Temperature and Salinity in the Taiwan Straits in August, 1999

The distributional features of sea surface temperature and salinity (SST and SSS)in the Taiwan Straits have been analyzed using the SST and SSS underway measurements in August, 1999. The characteristics of SST and SSS are summarized as follows: There are several upwellings and diluted water in the Taiwan Straits. The upwellings are divided into two kinds: those along the western coast of the Taiwan Straits and those around the Taiwan Shoal. There are three sources of diluted water: diluted water of the Jiulongjiang River,diluted water of the Zhujiang River and diluted water of the Minjiang River.
