| 摘 要： | 针对均匀水体假设的海水透明度经验计算公式不具有普适性的缺点,将海水在垂直方向上分为若干光学性质相近的均匀层,推导出非均匀水体中目标对比度传输方程,在此基础上,建立了海水透明度的计算模型。利用BROKE_WEST_ACS实测的海水固有光学性质数据和透明度盘观测数据,对计算模型进行了数值试验和效果分析。结果表明:模型计算值与透明度盘实测值平均相对误差为9.1%;该模型既克服了透明度盘测量易受天气状况和人眼差异影响较大的缺点,又突破了均匀水体透明度计算方法的局限性。 |

| Abstract: | Aiming at the faults of seawater transparency empirical formulas having no universality based on the assumption of homogeneous water transparency, seawater is divided into several homogeneous layers with similar optical property in vertical direction, and non-uniform water contrast transfer equation is deduced.Based on the contrast transfer equation, the calculation model of seawater transparency is established.The calculation model is used to do numerical experiment and effect analysis using the inherent optical seawater data observed by BROKE_WEST_ACS and the data from transparency plate.Results show that the average relative error between the model calculation values in the paper and the observed values from transparency plate is 9.1%.The model not only overcomes the disadvantages of observations from transparency plate, which are easily influenced by weather conditions and human differences, but also breaks through the limitation of uniform water transparency calculation method. |
