摘　　要：按照牛顿力学定律的要求建立了一种新型的时间系统,即依据日、地、月三体相互运动建立了一种潮汐时间系统;并选用了引潮天体(月球和太阳合成体)星下点处的整体引潮力为标志性引潮力。在该潮汐时间系统里潮运动就变成一种完全遵从牛顿运动定律的确定性运动,引潮力与潮汐和潮流形成一种确定性的因果关系。将之称为整体潮方法简称为整体法。将定义的引潮力和潮振动中的2种典型振动称为I型和II型,其相互转换周期为1/2回归月。因此,极大地简化了潮汐和潮流的计算和预报工作。本方法对固体潮和大气潮也有应用价值。In the light of the laws of Newtonian mechanics, and on the basis o sun, the moon, and the earth, a new tidal- only a symbolic force acting at the substellar tion of the moon and the sun. Therefore th timing system is defined, in which point of an imaginary celestial body f kinematics related to the the tide-producing force is equivalent to the combina e tidal motion relative to the tidal-timing system becomes de scriptive in accordance with Newtonian kinematics, and a causality seems to be formed for the relation between the tidal force and the observational data of the tidal level and current. This new method is called ＂ integration method＂. There are two types of fluctuations in the tidal force and tidal motion, i. e. , Type Ⅰ and Type Ⅱ, which alternates in a period of half an equivalent month for the imaginary celestial body, so that the complex tidal fluctuations can be simplified for the tide computation and forecast by means of the two types of tidal fluctuations. The method is also applicable in atmosphere tide and earth tide studies.
