摘要
使用压力式TGR-2050型验潮仪,在珠江口等河道入海口测量潮汐时,误差比较大;针对珠江口潮汐的特点,分析和研究了大气压扰动、潮流、海水密度、压力感应零点漂移等因素对潮汐测量带来的误差,有针对性地提出解决方案,并通过实验证明了方案的可行性。
It is relatively bigger poor error by using pressure type TGR-2050 tide gauge to measure tide for sea area of pearl river estuary. To solve this problem, the factors which can affect the tide error such as the atmospheric pressure disturbance, tidal wave, the density of sea water, the pressure sensor drift are analyzed and researched. And the solution is proposed. At last the experiment is done to prove the feasibility of the proposed solution.
