| 摘 要： | 日、月对地球表层海水的引潮力导致潮汐的周期性变化是一种成熟理论.地球除具有日、月、年潮汐规律外,还具有明显的准1800年、200年、50~70年、18.6年、9.3年和2.5~7年不同尺度的周期.本文通过将地球赤道半径和月球轨道半径投影到黄道面上,标定二者矢量半径之和的模的极值状态,创建了引潮力极大值和强潮汐的周期性指数KSEM.这对探讨和预测潮汐的时间分布和推断地球自转角速度变化规律提供了一种新途径.行星系统中木星和金星对地球的摄动影响最突出,但目前还没有一个行之有效的模型将日、地、月、木星、金星作为一个统一整体,对地球潮汐极值状态进行刻画.通过辨析这五大天体运动预设的位置关系的结构特征,进而考察KSEM指数与月球升交点和月球近地点会合周期的对应关系,以及对月球轨道运动不同的特征周期的叠加和定性分析,这对探讨强潮汐周期、厄尔尼诺现象和地震的时间分布规律提供了重要参考.

| Abstract: | A mature theory is that the tidal forces of the sun and the moon acting on the surface waters of the Earth cause periodic changes in tides. The tidal law of the earth not only has the law of day, month and year, but also has obvious cycles of different scales of 1800, 200, 50~70, 18.6, 9.3 and 2.5~7 years. In this paper the Earth’s equatorial radius and lunar orbital radius are projected onto the ecliptic plane. At the same time, the extreme state of the modulus of the sum of their vector radii are marked. The tidal force maximum and the strong tidal periodic index KSEM was created. The KSEM index is determined to reveal cycles of different scales as described above. A new approach is provided to explore and predict the temporal distribution of tides and to infer the variation of the angular velocity of the Earth’s rotation. In the planetary system, Jupiter and Venus have the most prominent influence on the perturbation of the Earth. But there is currently no effective overall model that can describe the Sun, Earth, Moon, Jupiter, and Venus for characterizing the extreme state of the Earth’s tides. The correspondence between the KSEM index and rendezvous cycle of the moon’s ascending node and the perigee is examined by analyzing the structural characteristics of the preset positional relationship of the five celestial movements. The overlapping summation of different characteristic periods of lunar orbital motion is analyzed. Important reference to the discussion of the strong tidal cycle, El Niňo phenomenon and the time distribution of earthquakes are provided. |
