As to the fourth strength theorem,there is still inadequate on application,so this paper at first starts from the theorem of molecular attraction and repulsion,then combining some experimental facts to revise the fourth strength theorem in order to make it more applicable.

This paper discusses the attraction between the origin and destination(O-D),the method of O-D distribution and its application.

A discussion on the relation between the gravitation affecting the Sun in the Galaxy and the distance r to the center of the Galaxy;

A clustering result evaluating algorithm is presented in a gravitational way,where all the data points in the data space are regarded as the particles assigned with unit mass.

The method of small parameter and setting up model of dumbbells are used to calculate the gravitational radiation of Double Satellite,and the expression of quadrupole radiation power is obtained.
