日、月引潮力的作用,使地球的岩石圈、水圈和大气圈中分别产生的周期性的运动和变化,总称潮汐。固体地球在日、月引潮力作用下引起的弹性——塑性形变称固体潮汐,简称固体潮或地潮;海水在日、月引潮力作用下引起的海面周期性的升降、涨落与进退称海洋潮汐,简称海潮; The role of the tidal force on the days and the tides makes the periodic movements and changes in the lithosphere, hydrosphere and the atmosphere of the earth, respectively, collectively called the tides. Elastic-plastic deformation of solid earth caused by the tide force on the moon and the moon is called solid tide, referred to as solid tide or earth tide; the seawater periodically rises, falls, Ocean tide, referred to as the tide;
