But for previous major tsunamis, scientists just had measurements that tide gauges recorded near the coast or that surveyors later estimated from water damage on land. 但相對于過(guò)去的大海嘯，科學(xué)家只能得到驗潮儀在岸邊記錄到的測量值，或是勘測員事后依陸地毀壞程度所做的估測值。
A mathematical model of tide zoning correction is proposed.Based on the computational model, a new tidal correction mode using single suppositive grid tide station is designed. 摘要提出了一種顧及潮時(shí)差變化的多驗潮站多邊形潮汐分區改正數學(xué)模型，設計了海量多波束數據通用的虛擬單驗潮站改正模式。
