通过对蓬莱沿岸海域多站位潮汐潮流实际观测,研究分析了其东、西两侧潮汐潮流特性.其中,受不同潮波系统控制下的半日分潮影响,蓬莱东、西两侧潮汐有较大差异,而全日分潮虽处同一潮波系统下,但量值较小、作用影响不大;东、西两侧潮流差异相对潮汐较小,半日潮流和全日潮流的变化特性与潮汐对应分潮的变化均不相同.%The context studies the tidal characteristics in the waters off the E and W coasts of Penglai according to the actual observations of multi-stations. Under the impact of the semidiurnal constituents controlled by different tidal systems ,the tides vary greatly on the E and W coasts,and the diurnal constituents with small magnitude is of less impact though under the same tidal system. The tidal currents there vary less as compared with the tides, and the changing characteristics of both the semidiurnal and diurnal tides and the changes of the corresponding partial tides are different .
